Title: Manufacture of semiconductor device
Inventor: OOKATA MITSUO
IPC: H01L21/58
Filed: 1980-11-18
Abstract: PURPOSE:To prevent breaking of wafers and overflow of brazing material by separating wafers after removing excessive brazing material by brazing holding plates on the surface of a wafer having a pn junction via a thin plate of the brazing filler. CONSTITUTION:In the manufacturing process of a power diode, for instance, a holding plate 3 consits of a round Mo plate is placed via brazing material such as Al on a wafer 1 on which a p<+> n n<+> deffused junction is formed. The holding plate is brazed to the wafer 1 by a heat treatment. The brazed structure is then dipped into the solution of dilute hydrochloric aid and excessive brazing material is removed by etching. The wafers are then separated in the shape of the holding plate 4 by punching following washing and drying process to make diode elements. This method decreases the occurence of inferior product while eliminating the effect of the brazing material 2 of a strong viscosity.

Title: Nonoxidation heat treatment of steel wire
Inventor: NISHIMURA TSUYOSHI
IPC: C21D9/56
Filed: 1979-12-14
Abstract: PURPOSE:To prevent the formation of oxidation scale by heating and austenitizing  the wire to be treated in a nonoxidative gaseous atmosphere and cooling the same  in the slow cooling zone of a nonoxidative gaseous atmosphere holding a proper  temp. region according to the steel kind and diameter of the steel wire. CONSTITUTION:While the steel wire 5 to be treated from a supplying device 1 is passing linearly in a heating furnace 2, it is heated to predetermined temp., thence it is slow cooled in a slow cooling zone 3 having been temp.-controlled, and is wound to a coiler 4. A nonoxidative gas G1 as an atmosphere gas is supplied to the heating furnace 2 and a nonoxidative gas G2 to the slow cooling zone 3. The temp. controlling in the slow cooling zone 3 is accomplished according to the steel kind and diameter of the steel wire 5, and the waste heat of the heating furnace 2 is used as a preheating source of the nonoxidative gas G2. It is equally well to send part or the whole of the nonoxidative gas G1 flowed to the heating furnace 2 to the slow cooling zone 3 and to use the same by mixing it in the gas G2. This causes the steel wire to be pearlitetransformed and obviates the formation of oxidation scale.

Title: Method of exposure to x-rays
Inventor: OKADA KOUICHI
IPC: G03F7/095
Filed: 1983-09-06
Abstract: PURPOSE:To copy micropatterns more precisely in X-ray lithography by coating the material to be treated, such as wafer, first with a low-sensitive negative type resist as a lower layer, and second, a high sensitive positive type resist in a specified thickness as an upper layer to form two coating layers. CONSTITUTION:The material to be treated, such as wafer 5, is coated with a low sensitive negative type resist layer 9 as a lower layer, and a high sensitive positive type resist layer 8 as an upper layer to form two coating layers. The film thickness of this resist layer 8 is set to a value little thicker than the transit distance of photoelectrons and Auger electrons (secondary electrons) of several hundred nm to use the layer 8 as a buffer layer against the secondary electrons. The coated wafer 5 is irradiated with a proper exact amt. of X-rays based on the film thickness of the lower resist layer 9, the X-rays are transmitted through the upper resist layer 8, and form an X-ray mask pattern in the lower resist layer 9. A large number of photoelectrons and Auger electrons 10 emitted from an Au pattern 7 are absorbed with the layer 8. As a result, all the layer 8 is dissolved in a development step to leave only the 100% cross-linked parts of the layer 9, and a copy having submicron wide high resolution can be ensured in this X-ray lithography.
