Title: Manufacture of beam lead type compound semiconductor device
Inventor: HARADA YASOO
IPC: H01L29/06
Filed: 1983-02-22
Abstract: PURPOSE:To realize uniform rear surface MESA etching by providing, between the base layer and low resistance layer, an intermediate layer which shows resistance for etchant used for etching of these layers. CONSTITUTION:An intermediate layer 14 in the thickness of about 10mu, for example, consisting of Ga0.5Al0.5As which shows resistance for the GaAs etchant is provided between the base layer 11 and low resistance layer 12. First, the rear side etching is carried out with the etchant of tartaric acid + hydrogen peroxide system. This etchant is not effective for GaAlAs and therefore an intermediate layer 14 is exposed. Next, the inermediate layer 14 must be entirely etched by the etchant of the fluoric acid system. In this case, however, this etchant etches the intermediate layer 14 and etching stops when the low resistance layer 12 of GaAs is exposed. Under this condition, the MESA etching which leaves the function element region using the photo resist technology is executed to the low resistance layer 12 and operating layer 13 of GaAs with the etchant of the tartaric acid + hydrogen peroxide system.

Filed: 1990-02-13
Abstract: PURPOSE:To intend volume reduction of a spent cladding tube by putting sheared segments of cladding tube of spent nuclear fuel into a heating furnace and by holding them at an elevated temperature in an oxidizing atmosphere to oxidize and to change them to fine particles or powder of a ZrO2. CONSTITUTION:Sheared segments 1 of nuclear fuel cladding tube of which material is a Zr or the like and from which spent nuclear fuel for a light water reactor is dissolved and removed, are placed on a table 2 in a heating furnace, and a mixed gas of an oxygen and an inert gas is supplied from a gas feed pipe 6. Then, furnace temperature is raised by a heater 5 and temperature higher than some 800 deg.C is held for appropriate time. By this heating process, the sheared segments 1 are oxidized and turned into fine particles or powder of a ZnO2. Since volume of the powder is smaller than that of the sheared segments, the number of metal containers for sealing it, can be reduced and also a room space for storing treatment can be diminished. Accordingly, the treatment cost can be substantially reduced.
