Title: Manufacture of magnetic memory element
Inventor: HIDAKA YASUHARU
IPC: G11C11/14
Filed: 1987-05-08
Abstract: PURPOSE:To improve the transmission stability of a Bloch line couple by providing a silicon film pattern on the stabilized area of a stripe domain constituting a magnetic memory element using the vertical Bloch line couple as a memory holder. CONSTITUTION:The pattern 3 made of a silicon film is disposed on the area where the domain needs to be held on a stripe domain holding layer 1, and an auxiliary pattern 5 made of silicon film is so disposed as sandwiching the separated areas along said pattern 3. Thereafter, a chip is heat-treated at 600-800 deg.C in ambient atmosphere of air or nitrogen for 30-60min, and the saturation magnetization of a domain holding layer 12 under the pattern is selectively made smaller. Then, the patterns 3 and 5 are separated, and on their both end sides, a domain generator 8 and a local in-plane magnetism generation means 9 are disposed. As a result, the steep film thickness difference of the holding layer surface around the stabilized domain can be eliminated, and the transmission capability of the Bloch line couple can be stabilized.

Title: Thyrister
Inventor: KAWAKAMI AKIRA
IPC: H01L29/74
Filed: 1978-09-11
Abstract: PURPOSE:To reduce dependency of the turn-off time upon the rise ratio of off-state voltage by decreasing the carrier injection efficiency of a 2nd emitter junction in the main thyrister domain comparing with the carrier injection efficiency of a 3rd emitter junction in an auxiliary thyristerdomain. CONSTITUTION:An auxiliary thyrister domain II of a PNPN composition is similarly provided in the center of the main thyrister domain I of a PNPN composition. The carrier injection of a 2nd emitter junction 15 in the main thyrister domain I is allowed to be given lower efficiency than the carrier injection of a 3rd emitter junction in the auxiliary domain II. For this reason, sandblast processing, gold diffusion, high impurities doping are carried out at the neighborhood of the exposure part of the 2nd emitter junction 15. Dependency of the turn-off time of the main thyrister upon the off-state voltage rise ratio dV/dt can be reduced without selectively increasing the leakage current on the surface of the junction 15 and lengthening the turn-off time of the auxiliary thyrister.
