摘要:
A method of transporting precision equipment materials without absorption of thermal energy through the heat sensitive material or device such as flat panel displays. The transfer member has a carbon fiber reinforced composite material body with a layer of metal film on the top and bottom surfaces of the transfer member that provides a reflective surface. Flat panel displays, for example, release radiant thermal energy that is absorbed by the carbon fiber reinforced composite which is detrimental to the flat panel display. The reflective surface created by the metal film prevents the energy absorption by the carbon fiber reinforced composite. A glass fiber and epoxy layer on the metal film surface protects the metal film.

To provide a wafer preventing a breakage of a crack or a chip off from being brought about in a polishing step and a polishing apparatus and a polishing method of polishing the wafer, there is provided a wafer in a shape of a plate substantially in an angular rectangular shape used as a raw material of a piezoelectric vibrator. All of corner portions D1, D2, D3, D4 substantially in the angular shape are formed in shapes of curved faces by chamfering providing curvatures. The corner portions D1, D2, D3, D4 in the shapes of the curved faces at least include a first curved face portion and a second curved face portion chamfered by curvatures different from each other or the same curvature. A reference face of a crystal orientation of the raw material is specified by the first curved face portion or the second curved face portion.
摘要:
The present invention provides a method for forming a silicon oxide film, with a substantially uniform film thickness and without being so influenced by dense sites and scattered sites in a pattern provided on an object to be processed, while keeping advantageous points of a plasma oxidation process performed under a lower-pressure and lower-oxygen-concentration condition. In this method, plasma of a processing gas is applied to a surface of the object having a concavo-convex pattern, in a processing chamber of a plasma processing apparatus, so as to oxidize silicon on the surface of the object, thereby forming the silicon oxide film. The plasma is generated under the condition that a ratio of oxygen in the processing gas is within a range of 0.1% to 10% and pressure is within a range of 0.133 Pa to 133.3 Pa. This plasma oxidation process is performed, with a plate, having a plurality of through-holes formed therein, being provided between a region for generating the plasma in the processing chamber and the object to be processed.

摘要:
A semiconductor device, which ensures device reliability especially in fine regions and enables great capacitance and high-speed operations, has memory cells including, in a first region of a main surface of a semiconductor substrate, a gate insulating film, a floating gate electrode, an interlayer insulating film, a control gate electrode, and source and drain regions of the second conduction type arranged in a matrix, with a shallow isolation structure for isolating the memory cells. When using a shallow structure buried with an insulating film for element isolation, the isolation withstand voltage in fine regions can be prevented from lowering and the variation in threshold level of selective transistors can be reduced. When the memory cells in a memory mat are divided by means of selective transistors, the disturb resistance of the memory cells can be improved.

摘要:
A control valve is configured such that as a position of a high pressure-side valve body positioned by a solenoid is closer to one side, a degree of opening for communication of a high pressure valve portion is more widened and a pressure on the side of a discharge flow path acting on the high pressure-side valve body is weakened. Further, the control valve is configured such that as a position of a low pressure-side valve body positioned by the solenoid is closer to the other side, a degree of opening for communication of a low pressure valve portion is more widened. When the high pressure-side valve body and the low pressure-side valve body are integrally positioned on the one side by the solenoid and the low pressure-side valve body is positioned on the other side by the solenoid, the high pressure-side valve body and the low pressure-side valve body are separated from each other.
