Title: Gerd Schliemann: Innovator in Semiconductor Technology
Introduction
Gerd Schliemann is a notable inventor based in Sunnyvale, California, recognized for his contributions to semiconductor technology. He holds two patents that showcase his innovative approach to improving integrated circuit manufacturing processes.
Latest Patents
One of Schliemann's latest patents is the "Automatic Wafer Loading and Pre-Alignment System." This invention provides an automated solution for loading and pre-aligning wafers in integrated circuit wafer-mask aligners. The system employs a belt feed track to transport wafers from a storage carrier to a pre-alignment station. It utilizes a roller arm and flat-finder system to mechanically pre-align the wafer with the aligner's chuck. After pre-alignment, the aligner turntable rotates to position the pre-aligned wafer while simultaneously preparing another chuck at the pre-alignment station. The system incorporates photosensors to detect wafer presence at critical locations.
Another significant patent is the "Air Bearing Piston Assembly for Semiconductor Mask-to-Wafer Aligner." This invention features a series of air bearings that create a low-friction environment for aligning a mask with a semiconductor wafer. The design includes small driver pistons that move a main piston, utilizing air bearings to ensure minimal friction. This innovative assembly allows for precise leveling of the wafer with the mask, enhancing the accuracy of semiconductor manufacturing.
