Abstract: PURPOSE:To ensure heat resistivity and improve quality by filling up a groove provided in an insulating film on a compound semiconductor substrate and Schottky junctioning it to the substrate and forming a gate electrode having laminated structure using a first and a second metal films. CONSTITUTION:On a GaAs substrate 1, having on the surface thereof an insulating film 2 provided with a groove 3 exposing the substrate, there is deposited a first metal film 4 consisting of WSi Schottky junctional to the substrate 1. SiO2 is deposited on the film 4 to fill up the groove 3 until the surface is made flat to form a film 8. The film 8 is etched back until the film 4 on the film 2 is exposed to form an insulating body 9 consisting of SiO2. Then, a Ti film 5, a second metal film 6 are deposited, and the film 6, the film 5 and the film 4 are patterned into the same pattern, and a gate electrode 7 having laminated structure is formed by using the film 4 and the film 6. Because the insulator 9 is interposed between the film 4 and the film 6, entrance into the cracks are prevented and heat resistivity is ensured.

Title: High-voltage generator for semiconductor device
Inventor: KIN MOSEKI
IPC: H01L21/822
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To prevent a turn-on of a P-N layer from being generated and to prevent generation of a latch-up in a high-voltage generator, by a method where in at the time pumping a well bias control means provided in the high-voltage generator, a well bias potential in an existing P-MOS transistor is adjusted. SOLUTION: A well bias in a fifteenth node N15 is decided in a high-level potential in either of an eleventh node N1 and a twelfth node N12 for adjusting a well bias in a P-channel MOS transistor of an existing high-voltage generator. When a high potential is applied to a fifth input terminal In5 in a state that a voltage is applied to the node N12 by a power-supply voltage, a potential higher than a high voltage (Vpp) results in being applied to the node N12. If the generator is constituted in such a manner, a potential in the node N15 is inputted in a well bias terminal of a twelfth P-channel MOS transistor MP12 and a turn-off of a P-N layer results in being prevented from being generated.
