Eric A Rost is a notable inventor based in Lincoln, NE (US). He has made significant contributions to the field of precision technology, particularly through his innovative patent that enhances substrate alignment processes.

Latest Patents

Eric A Rost holds a patent for a "High precision substrate prealigner." This invention features a prealigner that includes a light source and a light detector. The light detector is designed to detect the position of the periphery of a substrate as a rotary chuck rotates it. The prealigner is equipped with a processor that receives and records the peripheral position of the substrate relative to its angular position. By fitting a curve to the recorded data set, the prealigner can accurately determine the center of the substrate while eliminating any spikes in the data caused by notches or parts of the chuck. The position of the notch is also determined through curve fitting, allowing for precise calculations of the mid-point and offset error of the notch.
