Inventor: DONARUDO ERU PURAMUTON
IPC: H01L29/737
Filed: 1994-04-28
Abstract: PURPOSE: To obtain a buried gate field effect transistor, by forming side walls in a crystal orientation nearly equal to a substrate surface, and performing epitaxial excess growth of a Group III-V compound semiconductor on steps in the substrate. CONSTITUTION: A substrate 402 has (100) orientation and is made of an N<++> type GaAs wafer doped with silicon impurities of about 2×10<18> to 4×10<18> atoms/cm<3> . A gate finger side walls 409 substantially has the same orientation as the substrate 402. Of course, because of irregularity of etching, it is difficult to control the surface orientation within 5 degrees, but the surface orientation is nearly (100). An N type GaAs layer is grown by epitaxial process to fill spaces between gate fingers (channel region 410) and form a source 412 with a depth of 1.0 μm. As a result, a vertical gate field effect transistor for high frequency use can be obtained.

Abstract: PURPOSE: To enable a laser welding operation to be easily carried out to form a hermetically sealed case by a method wherein a hermetically sealing terminal which has such a structure that a through-hole is provided near each axial end face of a metal base provided with an elliptical drum and a flange, and a lead wire is inserted into the through-hole and sealed up with glass, an elliptical metal cap where the elliptical drum is fitted in to seal up, and a caulking means are provided. CONSTITUTION: The inner major axis of a metal cap 8 is set slightly smaller corresponding to the drum 3a of a metal base 3, and the inner minor axis is set slightly larger. When the hermetically sealing terminal 2 is fitted in the metal cap 8, the terminal 2 is required to be lightly press-fitted in the cap 8 because the inner diameter of the metal cap 8 is set smaller than the major axis of the metal base 3 by a length of α. But, as the inner minor axis of the metal cap 8 is set larger than the minor axis of the drum 3a of the metal base 3 by a length of β, the terminal 2 is easily press-fitted in the metal cap 8. Therefore, the fitting parts of the hermetically sealing terminal 2 and the metal cap 8 are caulked, so that a laser welding operation is efficiently carried out.
