Title: Method of marking
Inventor: KASHIWA MIKIO
IPC: H01L21/02
Filed: 1990-01-13
Abstract: PURPOSE:To facilitate marking and removal of deposit by making a groove composing an identification pattern in the specified region in a wafer and chemically corroding a section including the specified region in the direction of the depth of the groove. CONSTITUTION:The surface of a GaAs wafer of 3 inches in diameter is processed by mirror finish, the rear thereof is finished by etching after lapping, and the surface is marked. A YAG laser is used as a laser and beams are applied and scanned to the face of the wafer 1 for marking. After the marking, the surface of the wafer is removed by a thickness of 45mum by etching and mirror finish. In this case, in spite of removal of the surface having an about 5mum deep groove by a thickness of 45mum, the groove advances in the direction of the depth and is kept as deep as in the marking and widened only a little because of chemical polishing in the etching and mirror finish and no trouble such as unclear marking is caused.

Title: Insulated gate type field effect semiconductor device
Inventor: HAYASHI HIDEKI
IPC: H01L29/78
Filed: 1979-01-23
Abstract: PURPOSE: To obtain large logic amplitude of an insulated gate field effect semiconductor device by retaining the merit of a Schottky gate FET and enabling application of forward voltage thereto.  
     CONSTITUTION: An n-type epitaxial layer 22 is grown in gas phase on a semi- insulating silicon substrate 21, n + type source 23 and a drain 24 are diffused in the layer 22, a gate insulating film 25 is formed thereon to thus form respective electrodes. The MISFET formed according to this configuration operates substantially in the same principle as a Schottky gate FET, varies in the length of its depletion layer by the voltage applied to the gate electrode 28, and is controlled at the channel current flowing through the layer 22. Since this FET is the same equipotential type as the epitaxial layer at their source and drain, it hardly occurs a punch through effect. Thus, this FET can shorten the length of its gate to highly integrate its configuration and to accelerate its operation. Since this FET incorporates a gate insulating film, forward gate voltage may be applied thereto in case of using in an enhancement mode to thereby obtain large logic amplitude.
