Patent JP-2000036567-A (JP)
Title: Manufacture of cmos element
Inventor: RI SHOUKU
IPC: H01L21/316
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To improve mobility of a hole in a PMOS by forming a field oxide film for limiting a PMOS forming region in a thermally oxidizing step to receive a compression force by a semiconductor region formed of the PMOS. SOLUTION: A field oxide film 4 is formed in an LOCOS. This is because the degree of a compression stress to be received by a semiconductor layer 3 is different according to the conditions of a thermally oxidizing step like a temperature and a time. In the step, the stress to be received by the layer 3 is increased more as an embedded oxide film 2 is thinner. Accordingly, the stress of the layer 3 can be regulated by regulating the conditions and a thickness of the oxide film. The step is conducted at 1,000 to 1,2000 deg.C for 220 to 240 min in an oxygen atmosphere. A thickness of the film 2 is about 2,000 to 3,000 Å. Thus, mobility of hole in the PMOS element can be improved to a desired degree.

Title: Heating medium circulating type hot water supplying device
Inventor: YUYAMA HIROSHI
IPC: F24H1/00
Filed: 1983-10-05
Abstract: PURPOSE:To partition the stored hot water in portions with a plurality of temperatures respectively and consequently enable to perform energy saving operation by a structure wherein a partition wall to partition the interior of a hot water supply tank into the upper and lower portions is provided and heating heat exchanger is divided in series so as to heat the stored hot waters in said portions respectively and at the same time hot water supply pipes are arranged at the upper part of the respective stored hot water portions. CONSTITUTION:When hot water storage operation is performed, the high temperature refrigerant delivered from a compressor 1 enters a hot water supply tank 7 at its upper part and heats the stored hot water in an upper portion partitioned by a partition wall 12. After that, said refrigerant heats the stored hot water in a lower portion and enters an expansion valve 3. Because the amount of the stored hot water 11A in the upper portion is small, the temperature of the water 11A becomes high. At this state, the difference between the temperature of refrigerant condensed at an upper condenser 2A and the temperature of the stored hot water becomes small and the condensing capacity decreases. On the other hand, because the temperature of the stored hot water 11B in the lower portion is still low, the refrigerant condenses in the lower portion. If the high temperature hot water supplying load is developed, hot water is supplied from a hot water supply pipe 10A. At the same time, the stored hot water in the lower portion of the hot water supply tank enters the upper portion through a communicating pipe 12. Further, if the low temperature hot water supplying load is developed, hot water is delivered from a hot water supply pipe 10B provided at the lower part of the partition wall 12.
