Latest Patents

Arosha holds a patent for a "High precision substrate prealigner." This invention includes a light source and a light detector that accurately detects the position of the periphery of a substrate as a rotary chuck rotates it. The prealigner features a processor that records the peripheral position of the substrate relative to its angular position. By fitting a curve to the recorded data set, the prealigner determines the center of the substrate while eliminating any data spikes 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.
