Patent JP-S60140869-A (JP)
Title: Manufacture of semiconductor device
Inventor: HIKITA SOUICHIROU
IPC: H01L21/8234
Filed: 1983-12-28
Abstract: PURPOSE:To enable the simple preparation of an isolation layer for an active region by a method wherein a P type HgCdTe substrate is turned to an N type HgCdTe substrate by heating in an Hg atmosphere, and next an N<+> type layer isolating the active region is formed by the local heating with energy beams again in the Hg atmosphere. CONSTITUTION:The HgCdTe substrate has many Hg vacancies immediately after crystal growth and in therefore P type as a whole. The Hg vacancies working as acceptors are filled by the first heating to this substrate in an Hg vapor, and the donor concentration ND is set at approx. 10<15>. This substrate is placed in the Hg vapor, and the region for isolation layer formation to isolate the active region is locally subjected to the second heating with laser beams. When the substrate 2 is locally heated to approx. 400 deg.C, the Hg further thermally diffuses to the vacancies, and then the isolation layers 2a having an impurity concentration ND of approx. 10<17> is formed. Next, a CCD is produced by forming an SiO2 film 3 and gate electrodes 1a, 8a.... This manner simplifies the manufacturing process and improves the manufacturing yield.

Abstract: PURPOSE:To manufacture a hot dip tin coating copper wire having a plating layer of a uniform thickness having no unevenness by performing the hot dip tin plating by vertically moving the copper wire inside a hot dip tin plating bath when the hot dip tin plating is performed on the copper wire. CONSTITUTION:The molten Sn 21 in a two-bath type Sn plating tank 14, in which a molten Sn reservoir tank 11 and molten Sn dipping tank 12 are communicated with each other by means of a communicating section 13, is maintained under the same molten condition after the molten Sn 21 is put in the reservoir tank 11 by driving the piston 16a of a fluid cylinder 16b in the direction shown by the arrow A, by heating the molten Sn 21 with a heater 20. On the other hand, a softened Cu wire 22 pulled out from a softening device 17 is passed through the bottom die 24 of the empty dipping tank 12 and wound around a winder 19 by vertically lowering the wire 22 through cooling tanks 18 and 18'. By moving the piston 16a upward, inclining the plating tank 14, and injecting molten Sn into the dipping tank 12 through the communicating section 13, a molten Sn bath of a depth L is formed. Simultaneously, the Cu wire 22 is passed through the molten Sn dipping tank 12 and Sn plating is performed on thewire 22. Since the Cu wire moves vertically, the molten Sn does not form any thickened plating layer parts by its self-weight and a plating layer of a uniform thickness is formed.
