Together for the goal – AP&S is the main sponsor of the German athlete Christoph Kessler


“Together for the goal“ is the slogan, which accompanies the AP&S sponsoring of the middle distance runner Christoph Kessler. Since the beginning of 2017 the company has been the main sponsor of the athlete.

Christoph Kessler, born in Donaueschingen (city, where the company headquarters is located), convinces with his outstanding performance: 1st Place of the German best list in the 800 m run in June, 2 gold medals at the German Junior Championship in the 800 m race as well as in the 4 x 400 m relay he has already achieved this year in a row. Other exciting challenges such as the participation in the Universiade in Taiwan are coming soon.

“The success of Christoph Kessler is determined by hard training, which is associated with a great deal of discipline and passion for the sport. This commitment is admirable,“ says Alexandra Laufer-Müller, CEO of AP&S. “We met Christoph Kessler during an internship, which he completed in our company. We are pleased to support this dynamic, young man in achieving his sporting goals.”

Christoph Kessler about the cooperation: “I am glad to have AP&S as the main sponsor by my side. In the middle distance running speed, endurance and timing count. The exercise requires high force and time effort. The AP&S sponsoring allows me to concentrate on the two issues, which are of top priority for me: the sport and my studies in Process Engineering.“

At the first sight mechanical engineering and middle distance run have nothing in common. On closer inspection, however, parallels can be drawn. That is why AP&S has decided to use images of Christoph Kessler in a new advertising campaign. “Our wet process applications also focus on maximum speed in the production and endurance in terms of sustainable performance. The result is efficient application performance. We are already excited about the feedback from our target group on the new campaign. Further we hope that the campaign will attract more media attention on the middle distance running, which this challenging sport deserves,“ explains Aljona Barberio, responsible for marketing at AP&S.

AP&S offers a unique metal lift-off process for the LED manufacturing industry

Metal-lift-off, wet process tool, wet process solutions, single wafer

At the beginning of 2017 the AP&S metal lift-off process, which was launched in 2012 and runs successfully at several AP&S key customers sites within Europe today, was further developed and adjusted for the use in LED production.

“The lighting market is of high interest for our company. The semiconductor-based technologies like LEDs are on the rise and manufacturers of LED lighting systems are looking for reliable partners offering them depth of technical expertise and efficient solutions. The AP&S range already includes several wet process tools for this industry. However, we decided to further develop our existing metal lift-off process in order to meet the specific requirements of the LED sector. Now we are able to offer our customers a revolutionary solution, perfectly fitting to their key challenges like automated high volume production, prevention of damages on the substrate and ensuring of highest quality results”, says Uwe Müller, Director Business Unit Single Wafer.

The AP&S metal lift-off process is a single wafer spin process, offering three outstanding USP’s: 

  1. Superb solvent performance, without impact on substrate and structures
  2. Use of DMSO (dimethyl sulfoxide), an EH&S uncritical substance (EU & US)
  3. Optimized process time with an positive impact to the overall throughput 

Common wet chemical lift-off processes work with batch immersion or spray application, which often cause critical residues and x-contamination, such as metal flakes. Another commonly used technology for performing lift-off is based on the single wafer spin clean, which requires mandatory pre-soak and high temperature for solvents. Further disadvantage of these equipment technologies is the use of chemicals like NMP (n-methyl-2-pyrolidone) or Acetone. NMP is an EH&S critical substance, which causes severe irritation at skin, eye area as well as in respiratory system and carries the risk to damage fertility and harm unborn child. Acetone is highly flammable and residues after processing with acetone represent a well-known problem.

By using DMSO at elevated temperatures combined with Megasonic agitation AP&S metal lift-off process offers high safety for workers, environment and equipment and guarantees a constant solvent performance over an extended period. The process guarantees damage free lift-off for sensitive applications and sensitive substrates. There are no residues left on the substrate after processing and DMSO substance itself is easy to rinse off with DI water or lower solvent. For the AP&S customers it means low chemical consumption, cost reduction in the production chain and enhanced process capability.

The AP&S lift-off solution is available for all types of metal layers, alloys and further protection layers used in the semiconductor industry. All interested parties are welcome to test the AP&S metal lift-off process in the AP&S demo center, an in-house application laboratory at the company’s headquarters in Donaueschingen, Germany. “I look forward to welcome customers and potential partners in our demo center and to demonstrate them our unique metal lift-off process. Our whole process developing team is curious about receiving feedback concerning our specially adjusted solution for the LED market”, concludes Stefan Zürcher, responsible Process Engineer.


AP&S International GmbH achieves competitive advantage by investing in a new ultra-high purity water system

The investment of AP&S International GmbH (AP&S) in a ultra-high purity water system (UHPW) pays off. The system, with a state-of-the art concept brings not only pure water and cost savings, but primarily technological progress, considerable benefits for the customers and consequently competitive advantage for AP&S in the international equipment market.

Since the beginning of 2017 the new UHPW system is in operation at the AP&S manufacturing facility in Donaueschingen, Germany. The system reduces the impurities of city water residues up to the ultratrace level of <1ppb per cationic element. The system was installed by Hager & Elsässer (H&E) from Stuttgart, Germany. H&E provides industrial water treatment systems for more than 40 years and is one of the technological leaders in this field of UHPW concepts.

The main reason for the investment decision lies in the strong requirements on stability and purity of wet process applications in the semiconductor industry. Before a new wet process application can be used in production, it has to fulfill and demonstrate the required purity specifications. In practice, it means that before commissioning long-term rinsing and cleaning process at customer’s fab is necessary, which is associated with time, resources and material consumption.

The AP&S process engineer team recognized that an optimization of this process-set up would bring considerable advantages for the customers. Thus the basic idea for the project was born. In 2016, the investment and installation of the new UHPW system followed.

Stefan Zürcher, Process Engineer at AP&S, sums up the most important advantages of the new water system:  „Less water consumption and lower costs, associated with calculable risk of process hardware purity, which is monitored by on-line analytics, are the cornerstones of the new system. Additional new feature is that the used water can be recycled internally.  The UHPW system has a storage capacity of 6-8 m³ of UHPW and a production capacity of 3m³ water per hour. The purified water is used for rinsing, cleaning and conditioning of the AP&S tools and the facility. “

Prior to delivery to customers the AP&S tools are rinsed with the ultra-high purity water and qualified with optical particle counters (OLC’s @ > 0.1 μm resolution). Samples for trace impurity measurements are checked for cation concentrations typically to levels <1ppb each. An ICP-MS or GF-AAS is used in an external laboratory close by.

The value add for each customer is, that tools can be much faster qualified, less effort is needed on site and defect density requirements for production output can be achieved much faster.

„The new water system enables AP&S to provide customer wet process applications, which meet the highest SC-technology standards“, says Robert Preisser, Adjunct Professor at AP&S, who has initiated, specified and supported the project.

 „With the implementation of this advanced water treatment technology, AP&S has put itself at the forefront of the medium-sized equipment providers for wet process solutions, which support the semiconductor and nanotechnology industries around the globe“, adds CEO of AP&S Alexandra Laufer-Müller.

The most important innovation we presented during the exhibition was our optimized modular design which can be very cost-effective. The number of new contacts and concrete orders we have on hand is solid proof of the well-known quality of our wet bench solutions within the largest economy of the global market.

We would like to thank everybody for visiting our booth and, of course, look forward to seeing you again in the near future.

AP&S Open Day 2015

On Saturday, March 14, the official Open Day 2015 took place at AP&S headquarters in Donaueschingen.

The thought of providing our visitors with an exclusive "behind the scenes" tour of a plant manufacturer in the wet process technology, even if for a brief time, was entertained by nearly everyone from AP&S. One highlight of our open day was the tour through the manufacturing and clean rooms, where our guests gained remarkable insights into the AP&S wet process systems which are appreciated from customers all over the world.

Through the tour of our business processes in the production area, our visitors learned how AP&S has developed and grown over the last year. Most of our employees and guests had lunch, coffee and cakes. The younger ones (and also the youthful adults) enjoyed our bouncing castle.

We would like to thank our guests and all the contributors for this successful event and look forward to meeting them all again in 2016.


AP&S to invite members of surface expert group from "MicroTEC Südwest"

For several years the attendees of the “surface expert group”, a Cluster of MicroTEC Südwest, have been meeting on a regular basis. The 5th group meeting on January 29th was hosted at AP&S headquarters in Donaueschingen.

Discussions and knowledge exchange of “Light induced electroless plating of nickel on silicon”, “Application of plasma in surface treatment”, and many other topics were offered during various speeches and discussions. Dr. Michael Sowa, co-organizer and AP&S guest speaker, provides an insight of the meeting with the claim: "The really pleasant meeting environment was reflected by the large number of experts attending as well as the highly professional and cooperative working atmosphere. It's obvious that Germany and especially our region has many competitive high-potentials in the field of surface treatment."

Our thanks to all participants and especially to Dr. Christine Neuy, the responsible cluster manager from MicroTEC Südwest.

AP&S supports local school partnership with Sri Lanka

As a global manufacturing company, sustainability is embedded in the culture of AP&S. One result is our continued effort to strengthen and support the local project AJANTHA“.

This project was based on a concept from Realschule Donaueschingen and embraces several economic, social, cultural and ecological ideas. It is an approach to raise children’s awareness of something called the Fairtrade-Idea. With the skills the children have now participating in the local school employee trade company, they are producing, importing and selling regional Fairtrade-products from Germany and Sri Lanka.

By sponsoring flights or paying for several give-away articles we have been contributing for several years now to this project and are proud to give where we can make a difference in this project.

AP&S holds a view that is always focused on the future, and according to this principle the children of the Aasen kindergarten who are member of the "Technolino Group" were experiencing a funny day at our headquarters.

The "Technolino" project was initiated by the Südwestmetall employer association for giving the youth a playful insight into the basics of natural science and technology.

Working on their day task of forming a wooden moose, the kids were supervised by two of our trainees at AP&S as well as the kindergarten teachers. To experience AP&S business, which focuses on wet technology, the kids were equipped with a clean room outfit and had much fun with it.

At AP&S we do think that all children can be really proud of their results and wish them more funny days on their way to reach the "Technolino diploma".
