Title: Manufacturing method for thin-film transistor
Inventor: TERAUCHI MASAHARU
IPC: H01L21/265
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent the problem, where related to manufacturing of a polycrystalline semiconductor (Si) thin-film transistor, the resistance fluctuates when an impurity is injected through a gate insulating film, because the injection amount depends on the gate insulating film while a leakage current increases between a gate electrode and a source/drain electrode when it is injected, after the gate insulating film is removed. SOLUTION: A gate insulated film in an impurity injection region is removed to expose a polycrystalline Si, which is thermally treated in an oxidizing gas atmosphere to protect the surface of polycrystalline Si with an oxide film, while a damage which occurred in a process of removing the gate insulating film is recovered. The thermal treatment is performed again after impurity injection, and atmospheric gas is elaborated at thermal processing.

Abstract: PURPOSE:To provide a microwave oven with a heat generating body which can take a desired shape freely and has high strength in use and reduces unevenness in temperature distribution by connecting a microwave absorbing material which has particles or powder of carbon silicate as its main composition ingredient and has its particles mutually bound with a resin binder in silicon family and attaching the carbon silicate body to a metal plate by adhesion to form a heat generating body. CONSTITUTION:If microwaves are emitted to a heat generating device 5 they invade from the side of a lower outside vessel 7 and pass through a heat insulation layer 9, and they are absorbed by the particles 8b of carbon silicate of a heat generating body 8 and the latter generates heat. The heat in this heat generation is conducted to a metal plate 8a and from there the heat is radiated. The radiated heat passes through a heat convection channel 12 to heat uniformly the whole of an inner vessel 10. With this constitution because the base material is the metal plate 8a, it can be machined in a desired shape as needed while if unevenness in temperature develops in the layer of carbon silicate powder 8b, the temperature distribution in the heat generating body 8 becomes uniform because of the base material of good heat conductivity, that is, the metal plate 8a. Further, because of the metal base material the strength is high and it is possible to prevent breakage of the heat generating body.
