Latest Patents

One of Abe's latest patents is an optical instrument for measuring the shape of a wafer. This innovative device features a pair of optical profile measuring systems positioned to face both surfaces of a wafer, which is vertically supported at its edge. A thickness gauge with multiple sensors is strategically placed between the optical systems to measure thickness at various points on the wafer. Each optical system includes a light emitter that discharges a measuring light beam, a collimator lens to rectify the beam, and a light detector that receives reflected light beams from the wafer's surface. The computer processes the interference fringes created between the wafer surface and a referential plane, allowing for the calculation of the profiles of both surfaces and determining the real shape of the wafer.

Another significant patent is for a flattening machine, which is designed with three columns arranged in a triangular formation. A saddle, which secures the main spindle, is held in contact with the side face of the column or a brace connecting the columns. Multiple chucking tables are installed on an indexing table, allowing for efficient loading and unloading of workpieces. The main spindle's position at the geometric center of the triangle ensures that the reaction force during machining is evenly distributed, preventing deformation and ensuring superior flatness in the machined workpieces.
