Abstract: PURPOSE:To reduce the number of masks used for the manufacture process of a gate electrode by removing the contact layer between the first gate electrode formation area and the first and second insulating areas and making E-type and D-type elements separately. CONSTITUTION:A pattern 37 comprises a pattern 37a for removing contact regions in a first gate region 120 for a first gate 23 of an E-type HEMT and in a first insulating region 130 for isolating the first gate electrode from a contact layer 35 around the first gate region 120. The pattern 37 further comprises a pattern 37b for removing regions in a second insulating region for isolating the contact layer 35 from a second gate 25 around a second gate region 150.

Inventor: INOUE KIYOSHI
IPC: B23H9/14
Filed: 1992-01-13
Abstract: PURPOSE:To increase the machining speed in the electric discharge machining to bore a thin hole, by supplying machining liquid effectively, and generating a stable performance of machining. CONSTITUTION:A thin hole discharge machining device to performs electric discharge machining while supplying machining liquid into a machining hole in the jetting state by the use of a thin pipe electrode 1 is equipped with devices 9, 10 as jet flow supplying device for the machining liquid which supply the machining liquid upon turning into a ripple stream at least over 1.5Hz. Thereby the wave height value of the ripple stream becomes a very high pressure momentarily and then a low pressure on the next moment, and repetition of them in reversals at certain intervals allows flowing of a large quantity of machining liquid into the processing gap, which enhances the cooling effect to a great extent. Because the gas and/or the splash accumulated in the machining gas is given a vibration by ripple stream, it can be removed more easily. Accordingly a high speed machining is achieved in stable operating condition.
