Wafer Transfer Control Software

I wrote a wafer router for a single wafer CVD process tool. This router was quite efficient and flexible, responding appropriately to changes in processing times for different chambers. The system was able to achieve a substantial throughput advantage over its competitors.

300mm Factory Automation

I have done field support for a full 300mm Factory Automation implementation. This required getting to know the client’s code well enough to help the customer’s engineers as well as using tools like SECSIM to do experiments and show them specific messages.

Complete port of Spectrometer software to windows

I ported a client’s Dos-based products to Windows. I created a common user interface look for the whole product line. The products are spectrometer based film thickness monitors, & endpoint detectors. I also imposed source code control in that company, which they had not bothered with before.

HSMS Protocol

I implemented the HSMS protocol for a factory automation client. Semiconductor companies automated their wafer fabs using this product. This protocol implementation was the path between the factory host and all of the individual equipment in the fab.
