摘要:
A conventional lapping process of executing element size control and surface roughness reduction at the same time is divided in the present invention into a lapping process for element size control and a lapping step for surface roughness reduction. In the lapping process for surface roughness reduction, a surface of a ceramic substrate portion is used as a stopper for limiting cut-in of abrasive grains to realize surface roughness reduction while maintaining productivity.

摘要:
A plasma processing device include a plasma generation unit for generating plasma by using a cathodic arc discharge, first and second magnetic field ducts arranged in a row for transporting the plasma with one end of the row being connected to the plasma generation unit and a processing chamber connected to the other end of the row unit and having a stage for holding a substrate to be processed. A shutter is provided for covering the plasma during a period of a predetermined time after start of arc discharge or during a period of predetermined time before end of arc discharge. The shutter is disposed between the first magnetic field duct and the substrate to be processed, and is movable. The shutter is capable of being supplied with a voltage, and is kept in a state so as to be electrically insulated from the processing chamber.
摘要:
In the plasma processing device which utilizes a low pressure arc discharge, a method for efficiently capturing and removing electrically charged particles and neutral particles having no charge which are at most 5 &mgr;m in particle diameter is demanded. The electrically charged particles can be captured efficiently by installing an electric field filter in a transportation course of plasma. The electric field filter has a cylindrical structure which is uneven in inner wall shape. A voltage in the range of 10 to 90 V is applied to the electric field filter. The neutral filters can be captured efficiently by installing a neutral filter having an opening sectional area which is at most 40% of a sectional area of the transportation course.
