Title: Manufacture of semiconductor device
Inventor: USAMI TOSHIRO
IPC: H01L21/322
Filed: 1984-12-06
Abstract: PURPOSE:To contrive the restraint of generation of defects in the vicinity of a surface of a wafer and the reduction of cost of products by depositing a polysilicon film or a silicon nitride film on a semiconductor substrate after forming an oxide film on the substrate and further subjecting it to a heat treatment at 1,150-1,250 deg.C. CONSTITUTION:An N type silicon substrate 1 is subjected to a heat treatment at 950 deg.C in an oxygen atmosphere and a thermal oxidation film 2 is formed on the surface of it. A polysilicon film 3 is deposited over the whole surface by an LPCVD method and wafers are inserted in the four heat-treatment reactors which are different in a degree of purification, and in which a heat treatment is effected in N2 atmosphere at 1,200 deg.C for 5hr thereby forming a low-oxygen layer 4 on a surface of the substrate 1. Further a heat treatment is carried out in N atmosphere at 700 deg.C for 10hr thereby forming an oxygen deposited nucleus layer 5 inside the substrate. After removing the polysilicon film 3 by chemical dry etching, the thermal oxide film 2 is removed followed by mirror finishing of the surface of substrate 1. The elements are formed on the surface of substrate 1 to fabricate a semiconductor device. Thus the density of defects on a surface can be kept at a low level constantly of a constantly for a long time regardless of the purification degree of the heat-treatment reactors.

IPC: H01L21/02
Filed: 1991-09-10
Abstract: PURPOSE:To prevent the generation of a punch-through even in both an NMOS transistor and a PMOS transistor, and to enable the increase of density by shortening a channel. CONSTITUTION:An Si layer 14 as the active region 18 of a PMOS transistor 26 is made thinner than an Si layer 14 as the active region 17 of an NMOS transistor 24.

IPC: B23K11/06
Filed: 1987-10-14
Abstract: PURPOSE:To improve welding efficiency by interposing and arranging a differential mechanism between two couples of driving wheels and a motor and driving a welding machine by one motor. CONSTITUTION:Two planetary bevel gears 7 are provided crosswise with respect to a rotation axis 6 and engaged with bevel gears 8 and coupled with parallel gears 9.
