Computer Communication Engineering: Windows NT Tech Demonstrator & Core Hardware Integration for KLA-Tencor

We co-developed a critical Technology Demonstrator for KLA-Tencor's global semiconductor wafer inspection systems, deploying advanced computer communication engineering to resolve a major legacy hardware crisis under extreme time constraints.

The challenge involved replacing a deprecated core hardware controller (MicroVAX distributed network) with a modern software solution. Operating in the early days of Windows NT in 1995, we established an innovative, non-standard communication protocol to bridge high-resolution graphical interfaces with the low-level firmware of the legacy machinery.

Faced with a lack of dedicated physical messaging channels, we reverse-engineered the core networking pipelines. By isolating the legacy system's ASCII 7-bit patterns, we engineered a virtual multiplexing layer using the 8th bit as an isolated, filtered signaling route. This advanced communication layer successfully enabled full bi-directional messaging and graphical MMI operations without disrupting legacy code logic or generating system collisions.

By combining rapid prototyping with defensive code boundaries to prevent erroneous physical operations, the entire multi-disciplinary system was engineered from scratch to a production-ready demonstration in a record breaking timeline of just 3 weeks, ensuring a highly successful validation before KLA's global board of directors.
