| Novellus Systems was acquired by Lam Research, and I was part of the transition evaluation team assisting software management in fact finding/decision making regarding merging of the two software organizations and their utilized technologies. In addition, I designed and implemented various components to create integrations for the three Software Control systems in use, primarily on the realtime control side, including:<br>
: Software development of several hardware control systems using EtherCAT running on WindRiver vxWorks. The systems implemented a hard realtime script engine based on an vendor specific protocol; embedded C/C++ and SmallTalk
: Development of High-Speed Data Acquisition system connecting different field bus types to the data storage system, implemented in C++ and Java
: Bridging SmallTalk based control system to more modern systems using MQTT + Java applications

|-
|
| Principal architect of the next generation, distributed equipment control framework for the entire product line of the company.<br>
This distributed framework uses several types of Java/JVM's, including Embedded/RT-Java.<br>
Objectives for the control side was emphasis on high reliability and scalability, but also had to enable easy integration of a large variety of motion controllers and process control devices in an easily extensible manner. <br>
The data acquisition side needed a highly scalable data transmission and storage system for 1MM+ I/O updates/second. In addition, objectives was enabling integration of external software components and libraries into finished end-user applications.<br>
I was responsible for the software architecture and the technical leadership in this $12+ Million, 50+ man year project, being used in production since 2007.<br>
Along with the system architecture, I was in charge of the design and partial implementation of the realtime control components, I/O interface, configuration management, factory interface, SEMI Interface A development, data acquisition, wafer sequencing, etc. <br>
