    摘要: A valve body 10 of an expansion valve 1 comprises a valve chamber 14 to which refrigerant from a compressor is supplied. The amount of refrigerant is controlled between a valve member 40 and a valve seat 16, and travels through a first passage 20 to an evaporator. The refrigerant returning from the evaporator travels through a second passage 50 and into the compressor. The valve chamber 14 is equipped with a bypass passage which is communicated through a narrow hole 24 to an opening 26 with a bottom, and through a conduit 28 to the first passage 20. The electromagnetic valve 100 comprises a plunger 130, and opens/closes the bypass passage by a pilot valve 150. A pressure switch 220 is equipped to an opening 54 communicated to the second passage 50, and when the pressure of the refrigerant returning from the evaporator is reduced, the valve 100 is operated and the bypass passage is opened.

    摘要: A part of a gate insulation film between a semiconductor substrate and an exposed gate electrode of a semiconductor device is partially and stepwise etched away. A voltage is applied between the semiconductor substrate and the gate electrode in a chemical wet etching system at each step. An anode oxide film is formed on the surface of the gate electrode in a step, when a defect is included in a gate oxide film. The gate electrode is etched away in another step, when a defect is not included in the gate oxide film. A position of a defect in the gate insulation film is detected from the difference in the area of the gate insulation film when an anode oxide film is formed on the gate electrode, and when the gate electrode is etched away.

Specifically, each of the gate electrode portions (23) consists of a gate oxide film (19) formed on a side surface (S1) and part of the bottom surface (3B) of the trench (3), an FG electrode (20) formed thereon, a gate insulating film (21) formed on a side surface of the FG electrode (20) which is out of contact with the gate oxide film (19), an upper surface of the FG electrode (20), a side surface (2S) and the other part of the bottom (3B) of the trench (3), and a CG electrode (22) formed so as to cover an upper surface of the gate insulating film (21). Each of drain regions (11) is shared by the two adjacent transistors. The device configuration as above achieves reduction in area of the gate electrode portions (23) and further reduction in each level difference between both regions having and not having the gate electrode portion (23). Thus, reduction in level difference of each memory cell is achieved while reduction in area of each memory cell is ensured.

    摘要: The method is to selectively etch the etching residue in non-conductive state occurring in semiconductor manufacturing process. A silicon substrate cassette is used in such selective etching. In removing the etching residue in non-conductive state occurring in semiconductor manufacturing process, by applying a positive potential to part of conductive silicon substrates in an etching solution, the contact surfaces between the silicon substrates and the portion electrically connected thereto and the chemical etching solution are anodically oxidized to protect with a passive film, while only the etching residue in non-conductive state is selectively removed by isotropic etching, thereby achieving the purpose.
