Patent JP-H02256126-A (JP)
Title: Alloy thermal fuse
Inventor: UEMURA MITSUAKI
IPC: H01H37/76
Filed: 1989-03-28
Abstract: PURPOSE:To sufficiently secure an amount of flux to an amount of a low melting point metal by specifying the ratio of the outer diameter of the low melting point that of a coating layer of the metal. CONSTITUTION:An outer diameter R of an insulating layer 11 is sq. rt. 2 to 2.4 times the outer diameter rn of a soluble metal member 2 of a low melting point. A flux 3 is applied in a thickness a little larger than the outer diameter R of the insulating layer 11 and is inserted into an insulating cylinder 4. The amount of the flux 3 will be more than needed if the outer diameter R of the insulating layer 11 is more than 2.4 of the outer diameter r2 of the soluble metal member 2. This results in a too narrow gap between the insulating cylinder 4 and insulating layer 11 so that it is difficult to inject sealing agent into the gap. Division and formation into phere, of the soluble metal member 2 are therefore promoted when a thermal fuse operates in spite of carbonization of the flux 3 due to arc. Accordingly, quick operation of the thermal fuse can be enhanced.

Title: Formation of integrated circuit
Inventor: FUREDERITSUKU TEI BURADEI
IPC: H01L21/336
Filed: 1994-04-18
Abstract: PURPOSE: To prevent a latch-up and to increase the breakdown voltage by implanting neutral impurity ions into a silicon transistor element. CONSTITUTION: An element 10 has a substrate 12, a buried insulating oxide 14, a drain region 16 and a source region 18. A main body region 24 is a channel region under a gate between the source region and the drain region of the element. In a treatment operation, an annealing treatment is performed after neutral species are implanted to remove a damage caused by implantation. Since the neutral impurities include VIII group atoms such as krypton, xenon, germanium and the atoms are large in size and cause turbulence in a band structure, the scattering centers to high energy carriers in a transistor increases. When a drain field having a neutral impurity center is constant, a collision ionization current decreases and a parasitic bipolar effect also decreases, which can prevent a latch-up and increase the breakdown voltage.
