Vaduz, Liechtenstein

The company's product was a state-of-the-art wafer-surface inspection tool usinglaser illumination, sensitive darkfield optical detection and fast precision wafer handling. It handled up to 8 in wafers in its own cleanroom class 1 environment and could detect particles down to almost 0.1 um diameter. My responsibilities included: System and subsystem test with technical feedback for design improvement. Definition of acceptance testing involving calibration of scattered light intensities using own waferstandards coated with polystyrene latex spheres of various diameters Technical marketing support. Applications. Customer support at sites in Germany, Italy and USA.

Vaduz, Liechtenstein

Testing and evaluation of the step-and-repeat (stepper) optical lithography tools subsystems, providing reports to aid their further development. Final acceptance testing of SRA-100, SRA-200 and Micrastep instruments in production using an optical lithography process and evaluation of exposure patterns in developed resist. Installation site support at chip fabs in Europe and USA.

Balzers, Liechtenstein

Wrote program to automate the characterisation of temperature coefficient of resistance of thin film resistors. Designed layout of a laser-trimmable precision thin film resistor. Designed layout of thin film resistors for microwaves, helped with their manufacture using rubylith film and their characterisation at the ETH Zürich.
