Wet process development

Demo Center

Are you looking for a wet process solution that perfectly meets your specific requirements? An investment in a wet process tool is an important decision in which many decisive aspects and complex interrelationships have to be taken into account. AP&S supports you efficiently in the decision making process:

Our process engineers support you in process development and modification for standard as well as innovative semiconductor materials like SiC, GaN-on-Si/SiC, InP.  In the AP&S wet process lab you get a concrete comparison of process performance and parameters on different wet process equipment as well as analysis and recommendation for drying processes for deep structures, MEMS, TSVs. Here you will get all necessary information for a well-founded investment in your next wet process tool.

AP&S Demo Center in figures: 

66 square meters clean room environment according to ISO5; 6 process engineers; more than 25 different chemical wet processes. 

Demo Center

Process experience

In the AP&S Demo Center you can see the wet process applications, which are of interest for you, in live-operation. Our high-qualified process engineering team will explain you all details of the wet process tool and will answer your questions. You will receive a comprehensive test report containing complete parameters of the process set-up, a recommendation for process recipe due to test results and further important system configuration details.

Demo Center

Quality Check

The AP&S Demo Center has state-of-the-art testing and analysis equipment such as liquid particle counter SLS1100 and air particle counter LASAIR III 110. In addition, we run joint research and development projects with innovation-driving research institutes worldwide.
