Filed: 1987-09-07
Abstract: PURPOSE:To make it possible to manufacture a field effect transistor having large mutual conductance and capable of operating at high speed with good repeatability, by selectively growing an N-type semiconductor layer by an MOCVD method using an insulating side wall and a gate electrode as a mask and then etching it such that it becomes partially thin. CONSTITUTION:An undoped GaAs layer 3, an N<+> AlGaAs layer 2 and an undoped GaAs layer 1 are sequentially superposed on a semi-insulating GaAs substrate 4 and a gate electrode 5 is formed to form insulating side walls 6a and 6b comprising SiO2. An N<+> GaAs layer 7 is selectively grown by an MOCVD method using AsH3 and trimethylgalium and thinned by selectively etching the layer 7. Finally, an ohmic electrode (Au Ge) is provided on the thinned part to form a source electrode 8 and a drain electrode 9. Since the N<+> GaAs layer can be formed thickly, sheet resistance is decreased and since the part right beneath the source and drain electrodes is thin because of the etching, contact resistance can be reduced.

Filed: 1984-10-26
Abstract: PURPOSE:To change polysilicon into a single crystal by forming a metallic film on a boundary between silicon dioxide in the thin section of the film thickness of silicon dioxide and a quartz substrate. CONSTITUTION:A thick region 12 in silicon dioxide formed onto the surface of a quartz substrate 11 and the thin section 13 of an silicon dioxide film as heat sink structure are shaped, and a polysilicon film 14 to which a single crystal must be formed is shaped onto the surfaces of the region 12 and the thin section 13. A metallic plate such as a molybdenum plate 15 is formed to the thin section 13 of the silicon dioxide film. Since the metallic molybdenum film has excellent thermal conduction to heat transmitted through the silicon dioxide film having heat sink structure of heat by laser beams 16 as continuous waves, the molybdenum film displays an effect in which heat is soaked extending over the whole surface of a device region, and a change into the single crystal progresses during thermal conduction because heated heat quickly escapes. Polysilicon can be turned into the single crystal by irradiating such a quartz substrate by a laser as continuous waves through a normal method, thus enabling the change into the single crystal with high reliability in an SOI having heat sink structure.
