CONSTITUTION:The effect of preventing the silver disolving is synergistically improved and the content of Ag is decreased by making combination use of Bi and Ag. The m.p. is adjusted by the content of Bi. The preventiveness of the silver disolving is considerably increased by the addition of Cu. Namely, Sn which is the essential component of the solder alloy is incorporated at 20-90% at which the sliver disolving is effectively prevented and the m.p. is increased to prevent the deterioration of the adhesiveness. Bi is incorporated therein at 1-30wt% to provide the effect of making the combination use of Bi and Ag and to prevent the deterioration of the mechanism strength. Ag is incorporated at 0.2-2.0wt% which is the min. limit to provide the effect of making the combination use of Sn-Pb-Ag. Cu is used at 0.1-1.0wt% at which the m.p. is increased and the deterioration of the adhesiveness is obviated. The solder alloy is made wider in the m.p. by the above-mentioned formulation, by which the amt. of the Ag to be used is decreased and the cost is reduced.

Title: Resist coating method
Inventor: NISHIMURA HIROSHI
IPC: G03F7/16
Filed: 1991-08-23
Abstract: PURPOSE:To prevent the periphery of a substrate from being coated with resist by performing surface treatment on the periphery of the substrate using surface treatment agent which reduces critical surface tension before resist coating treatment. CONSTITUTION:The periphery 5b of a rectangle substrate 5 is treated by, for example, hexamethyl disilazane (HMDS) to form a several hundred molecular layer and the HMDS layer 7 which contains large quantity of methyl group is formed on the surface of the periphery 5b. The part of the HMDS layer 7 which makes contact with the surface of the substrate 5 has O-Si-(CH3)3 which adheres well to resist 6, in the vicinity of the surface of the HMDS layer 7, however, almost no O-Si-(CH3)3 is present and only HMDS is present. Therefore, wettability of the surface of the periphery 5b of the rectangle substrate 5 is deteriorated after the HMDS treatment and the surface repels the resist 6. Therefore, after the HMDS layer 7 is formed, even when the rectangle substrate 5 is coated with the resist by a resist pin coating device, the periphery 5a is not coated.

Title: Semiconductor device and semiconductor storage device
Inventor: TAKEDA YASUHIRO
IPC: H01L21/822
Filed: 1994-09-05
Abstract: PURPOSE: To provide a stack-type memory cell which allows small leak current. CONSTITUTION: A contact hole 2 is formed so as to make contact with the edge (bird's beak part) of a field insulation film 52. On the interface between the edge of the field insulation film 52 and a substrate 51, small lattice defects are generated due to stress from the field insulation film 52. If such lattice defects are not generated, stress applied to the substrate 51 from the edge of the field insulation film 52 causes leak current increase. An area of the junction depletion layer that crosses the part whereupon the lattice defect is generated or stress is applied can be reduced and prevent junction leak increase by covering such part with a source/drain area 1. As a result, leak current due to the field insulation film 52 can be reduced.
