Title: Innovations by Thomas E Leonard
Introduction
Thomas E Leonard is a notable inventor based in Vernon, CT, who has made significant contributions to the field of technology with a total of five patents to his name. His work primarily focuses on advancements in wafer grinding machines, which are essential in the semiconductor manufacturing process.
Latest Patents
One of Leonard's latest patents is the Wafer Grinding Machine. This innovative machine utilizes a centrally located robot to efficiently move a wafer from an input station to a measuring station. After the measurements, the wafer is sequentially transferred to a grind station and then to a wash station. The design allows for simultaneous processing, as a second wafer can be held between the measuring and grind stations while the first wafer undergoes after-grinding measurements.
Another significant patent is the Seal Assembly for a Wafer Grinding Machine. This assembly is mounted on a housing that contains a grinding wheel. It features a pair of flexible strips that sealingly engage the planar surface of a wafer introduced through an opening by a rotatable chuck. The design includes a V-shaped gap to ensure the edges of the sealing strips are biased against each other and the wafer, while a perforated tube blows air to clear debris from the wafer.
