Title: Manufacture of semiconductor device
Inventor: FUSE HARUHIDE
IPC: H01L27/04
Filed: 1988-01-13
Abstract: PURPOSE:To restrain the concentration of P<+> in a trench sidewall, and obtain a semiconductor device, e. g., a DRAM, having stable characteristics, by forming a P<+> layer by etching a trench two times, at the time of forming an isolating part trench on the upper part of an SCC structure. CONSTITUTION:An SiO2 film 2 is formed on an Si substrate 1. By using a selective photoresist mask, a trench 3 is formed on an isolating part and a trench capacitor forming part. By implanting boron ions, a P<+> layer 5 is formed. A depth of 0.3mum is dug, and silicon etching is performed. By vertical etching of SiO2, a side wall SIO2 6 is formed. By deep trench etching, a deep trench 7 is formed. By implanting boron 8 and As 10, a P-layer 9 and an N-layer 10 are formed. By digging the trench more deeply, and implanting B<+> ion vertically, the concentration of the P layer bottom part 9' is increased. Thereby the concentration of P<+> in the trench sidewall is restrained, and a semiconductor device, e. g., a DRAM, having stable characteristics is obtained.

Abstract: PURPOSE:To prevent the exhalation of malodor at the time of raw refuse throwing-in and the soaking of malodor into the frost inside a chest, in a refrigerator-equipped domestic or the like kitchen refuse storage chest, by providing a drawer type door to the refrigerator-equipped body, and detachably fitting a raw refuse vessel on the inside of the chest door, and further providing a cover capable of being freely opened or closed to the vessel. CONSTITUTION:The inside 12 of a chest is cooled by a refrigerator 17 to prevent decay. when a door 11 is pulled out, the door 11 accompanied with a kitchen refuse storage vessel 13 is drawn out along a guide rail 10, and the vessel 13 is placed in the kitchen refuse throwing-in position. And a cover 14 is opened for throwing in kitchen refuse, and then it is again closed. Accordingly, the opening time of the opening of the vessel 13 can be shortened to prevent the exhalation of malodor. And further, since the cover is closed, even after the vessel 13 has been housed inside the chest, the exhalation of malodor inside the chest can be prevented, and also the soaking of malodor into the dew water at the time of defrosting can be prevented. Thus, by this constitution, the exhalation of malodor can be prevented.

IPC: G01D5/12
Filed: 1982-01-18
Abstract: PURPOSE:To obtain the physical quantity transducer such as a highly accurate, electrostatic capacity type pressur difference transducer by holding a cylindrical detecting part and a magnet ring in floating state in a core by a magnetic force. CONSTITUTION:External pressure is guided to two pressure chambers 13 through an insulating fluid sealed in the inside, and acts on a magnetic fluid 18. As a result, a cell assembly 17 is displayed in the axial direction against the pressure P2 by a force f1 corresponding to the pressure difference DELTAP=P1-P2. Therefore the magnetic fluid 18 gives a force f2 to the cell assembly 7 in the direction against the force f1 of the pressure difference DELTAP. Then the cell assembly is stopped at the position where the forces f1 and f2 are balanced. The pressure difference DELTAP=P1-P2 simultaneously acts on a detecting diaphragm and deflects it to the low pressure side (P2 side). Then the electrostatic capacity between a pair of electrodes 2 and the detecting diaphragm 15 is changed. By measuring the change in said electrostatic capacity through a lead wire 20, the given pressure differene DELTAP=P1-P2 can be found.

IPC: A61B8/00
Filed: 1981-01-21
Abstract: PURPOSE:To eliminate the adverse influence of a shielding wire and to obtain a probe of high sensitivity by providing an impedance converter between the shielding wire and the probe. CONSTITUTION:A connector 11 connecting to a shielding wire from an ultrasonic image pickup device to a probe is connected to a transformer 12, and the secondary thereof is connected to a piezoelectric body 13. An inductance 14 is connected in parallel to the secondary side thereof. An impedance converter is formed of the transformer 12 and a coil 14 having an inductance Ls inserted to the secondary side. If the boosting ratio of the transformer is defined as (n), the impedance Z2 when the transformer 12 is viewed from the secondary side during receiving of waves is 1/n<2> times the load on the primary side, and the capacity of the shielding wire is 1/n<2>, resulting in that it is inserted in parallel with the piezoelectric body, thus the influence thereof is extremely small. Sensitivity is improved by the insertion of the coil 14 in the secondary side, and the parallel resonance conditions of the secondary side are achieved by the selection of the Ls alone, whereby the degree of freedom for the transformer is increased.
