Latest Patents

Tsai holds a patent for a "Confocal wafer inspection system and method." This invention provides a semiconductor wafer inspection system that utilizes a multiple element arrangement, such as an offset fly lens array. The system employs a laser to transmit light energy toward a beam expander, which creates an illumination field. The offset fly lens array converts this light energy into an offset pattern of illumination spots. The design includes a lensing arrangement that imparts light energy onto the specimen and passes it toward a pinhole mask, which is mechanically aligned with the offset fly lens array. This innovative approach allows for rapid sensing and includes an autofocus system that measures and cancels topological features of the specimen.
