DOCK/TOTAL QUALITY MANAGEMENT SYSTEM

ISO 9001:2008 Certified

 

Since our foundation, DOCK/TOTAL QUALITY MANAGEMENT SYSTEM has been based on stringent ISO standards and we hold an ISO 9001:2008 certification. Our plant in Marburg/Germany has state-of-the-art production equipment and follows our strict MOCVD platform approach. Every chemical we produce which reaches semiconductor purity is handled using MOCVD approved equipment and components. In this way we can ensure highest purity and consistency of our processes. Key to our quality system is the direct link to our customers processes. Our unique approach is to use epitaxial growth for specification of equipment and quality control.

EPIGRADE™ concept

 

EPIGRADE™ qualification is an essential part of the DOCK/TOTAL QUALITY MANAGEMENT SYSTEM. We are committed to improving our products in order to continually exceed the purity and consistency required for successful epitaxy. Our company has defined this unique service to guarantee the proven quality of each batch. Our customers benefit by reduced costs associated with qualification runs and potential down time.

A production batch that is EPIGRADE™ is tested by means of epitaxial growth of reference material systems and test structures specifically designed to be sensitive to impurities which are affecting the electronic and optoelectronic properties. The chosen structures are either sensitive to the majority or minority carrier properties, hence enabling a complete picture of the chemicals used for deposition.

These set of test structures are grown and characterized at an independent Lab (Philipps University/Marburg) and followed by physical characterization of the deposited compound semiconductor layer structure. Characterizations routinely performed include: Photoluminescence, Hall-measurement as well as calibrated SIMS. Other characterization methods are available on request.
