Member of a technical team to develope real-time system software for semiconductor manufacturing equipment.

Software Engineer with over 10 years experience in developing and testing real-time system software for semiconductor manufacturing equipment. Designed, developed, and tested system software for optics control and laser control subsystems. Wrote and reviewed Software Requirement Specification and Software Design Specifications. Experienced in developing software from requirements analysis through final system integration. Used Rational Rose software modeling tools for Object Oriented Software Development in C++. Trouble shoot for root cause when customers’ photomask inspection system did not run correctly.

Designed distributed and real-time system software for optics control module, laser control module and their applications for an image acquisition system used to inspect photomasks. Major accomplishments listed below.

Contributed to the development and the release of Teron SL650 by optimizing system software for optics system, laser system, and system uniformity calibration for a new reticle quality control inspection system for IC fabs supported 20nm design nodes and industry-leading production throughput inspection system.

Reduced 80% time of periodic maintenance for Uniformity calibrations when customers needed to have KLA-Tencor inspection machines to be serviced by developing and delivering system software to perform fast Uniformity calibration to reduce calibration time from 5 minutes to 1 minute per calibration. Also reduced the frequency of Uniformity calibrations from monthly to quarterly by enabling Inline Uniformity mode during normal operation to calibrate uniformity automatically in runtime.

Contributed to the development and the release of Teron 600 Series by developing and delivering new system software and its application frameworks for controlling new advanced optics system and new advanced NIKON 193nm-wavelength laser system for the industry's 193nm-wavelength reticle inspection systems addressed a major transition in mask design at the 2Xnm logic.

Reduced 10% cost of laser for not replacing laser head by developing and delivering system software for laser module and its applications to predict when laser needed to be calibrated and arranged maintenance to be performed automatically. Otherwise, laser head got damaged caused by missing lasers’ periodic calibrations.

Reduced downtime in production line caused by damaged laser by developing and delivering system software for laser module and its applications to predict end of line of lasers’ components. It allowed KLA-Tencor Customer Support Engineer/Technical Support Engineers (CSE/TSE) to order parts in advance before servicing inspection machines.

Developed and delivered all high level and low level interfaces for LabViews to call to enable laser alignment functions and diagnostics.

Contributed to the development and the release of TeraScanXR by enhancing and delivering system software for optics system and laser system to support changes to the optics, electronics, algorithms and computer which improved overall sensitivity to meet 32nm requirements for the industry only inspection tool on market to supply complete set of inspection planes: high resolution reticle-plane inspection (RPI) to capture process defects during development and manufacturing; aerial-plane inspection (API) to filter out certain non-printing defects; and wafer-plane inspection (WPI) to predict which reticle defects would be printed on the wafer.
