Title: Manufacture of thin-film layered superlattice structure
Inventor: TSUDA HISANORI
IPC: G02B1/02
Filed: 1985-12-24
Abstract: PURPOSE:To produce a thin-film superlattice structure having high performance in stable and efficient manner, by mixing and dispersing a film forming material excited by glow discharge or the like in another material activated by light, under application of light. CONSTITUTION:After an active species producing chamber A and an exciting species production chamber D are evacuated, Si2HD6 and C3H6 are introduced into the active species producing chamber A and into the exciting species producing chamber D, respectively, through material gas supply tubes 7 and 12. Microwave discharge is caused by a discharge causing device 11 so that carbon exciting species are produced in the chamber D. High-energy light 8 is applied through a light transmitting plate 4 so that Si-H active species are produced in the chamber A. A gate valve 9 is then opened to allow the C exciting species to enter into the chamber A and to be dispersed therein. Photochemical reaction is thereby caused and an amorphous SiC:H film is deposited on a substrate 3. According to this method, since the surface of the substrate is not shocked by ions or the like during the process, uniform films without any disorder or defect on the surface can be produced stably and efficiently.

IPC: G11B17/04
Filed: 1986-12-04
Abstract: PURPOSE:To reduce the size of a loading mechanism, especially of a slide plate and to minimize the size of a device by moving a backet and a setting member using one double-sided cam having a prescribed cam groove. CONSTITUTION:A cam groove 416 on one side surface of the double-sided cam 408 is engaged with a cam follower 318 of a slide plate 310 for sliding the backet 200 for guiding a magnetic sheet pack. On the other hand, a cam groove 417 on the other side surface of the double-sided cam 408 is engaged with a cam follower 604 of a main arm 600 of the setting member for the pack.

IPC: H01L21/3065
Filed: 1988-11-17
Abstract: PURPOSE:To prevent the corrosion of an Al conductor pattern by forming a conductor pattern on a thin film made of Al or Al solid solution on a semiconductor substrate, and then radiating it with an ultraviolet ray while heating the substrate to remove remaining chlorine by vaporizing. CONSTITUTION:After a thin film made of aluminum or aluminum solid solution is formed on a semiconductor substrate, a resist pattern is formed, and it is dry etched with chlorine gas as an etchant to form a conductor pattern. Then, an Si wafer in which RIE process is finished is placed on a hot plate, heated to a temperature higher than sublimation temperature, i.e., 200-300 deg.C to sublimate AlCl3. Here, if the heating temperature exceeds 300 deg.C, the Al starts to be recrystallized, and the accuracy of the conductor pattern is reduced. When the wafer heating and its irradiation with an ultraviolet ray are employed together, the removal of the AlCl3 is accelerated. Thus, corrosion can be substantially completely prevented.
