Microprocessor chips have found their way into a surprisingly high number of products that are around us every day in our home, car and office. This explosion in worldwide demand has forced semiconductor manufacturers to enhance quality and throughput in ways never before imagined. Capacitec's microinch level positioning sensing systems assist chip processing and handling equipment manufacturers to sense silicon wafers for exact positioning prior to deposition, etching and other processing where generating unwanted particles is preferred. This is accomplished without coming into contact or damaging their highly sensitive surfaces. Other industries where sensitive surfaces must be measured damage free are printing presses, photocopier rollers, computer hard disc drives and molten materials.
