Title: Formation of fine pattern
Inventor: SUDOU ATSUSHI
IPC: H01L21/28
Filed: 1983-09-10
Abstract: PURPOSE:To obtain fine patterns of high accuracy by a method wherein, in forming a conductor pattern on a semiconductor substrate, first a thin film pattern made of conductor is formed, and the same material is epitaxially grown thereon until it becomes a required film. CONSTITUTION:A thin SiO2 film 3 of approx. 5,000Angstrom  thickness is produced on the Si substrate, and a polycrystalline Si layer 11 of about 400Angstrom  thickness is deposited thereon by the CVD method. Next, it is covered with a mask 12 of a photo resist film of dimensions made as designed values and etched with plasma, thus being formed into a gate pattern of a desired shape. At this time, since the Si layer 11 is thin, the phenomenon of side etching does not generate. Thereafter, the mask 12 is removed, and a polycrystalline layer 13 is selectively grown on the layer 11 likewise by the CVD method, resulting in the formation of a gate electrode 4 of about 4,000Angstrom  thickness. When it becomes necessary to decrease the resistance value of the conductor pattern, W, Mo, etc. can be laminated on the layer 11; the thickness of the layer 13 is kept smaller by that amount at this time.

Inventor: KIDOUCHI YASUO
IPC: E03C1/044
Filed: 1986-07-16
Abstract: PURPOSE:To prevent hot water from being discharged when a shower is used, by changing over the destination of discharge to a faucet by the action of a temperature safely valve when the temperature of mixed hot water exceeds a prescribed one. CONSTITUTION:Comparing the temperature detected by a temperature detector 24 with that set by a setting apparatus 25, a controller 26 sends a signal to a mixing valve driving unit 23 in response to the deviation, and controls a mixing valve 20 so that the mixed hot water temperature becomes equal to the setting temperature. The temperature-controlled mixed hot water is discharged from either a shower head 28 or a faucet 29 via a changeover valve 27. When the mixed hot water temperature exceeds a prescribed temperature, the wax inside a wax type thermostat body expands to push out a rod 40. Thus, a safety lever 43 acts on the shower side valve body 31 of the changeover valve 27, and mixed hot water is discharged from the faucet 29.
