Abstract: One illustrative method disclosed herein includes storing a semiconductor manufacturing document in a document management system, wherein the semiconductor manufacturing document comprises semiconductor manufacturing data, and actuating an extractor tool to extract at least a portion of the semiconductor manufacturing data from the semiconductor manufacturing document and transfer the extracted semiconductor manufacturing data to at least one table in the semiconductor manufacturing database.

Abstract: The invention concerns a piston compressor for compressing a compressible medium. The piston compressor includes a compressor stage, which includes a piston guided in a cylindrical space as well as an inlet valve chamber connected with the cylindrical space through art inlet valve and an outlet valve chamber connected with the cylindrical space through an outlet valve. The inlet valve chamber is connected with the cylindrical space through an idle control valve. The idle control valve includes a valve body and a control body. The valve body inner space presents a connection with the cylindrical space of the compressor stage and the valve body outer surface shows a compensation opening connecting the valve body inner space with the inlet valve chamber.
