摘要： A ceramic membrane device for a photomask is a ring-shaped base plate constituting a circumferential frame and having a flat front surface, an outer side surface and a rear surface, a front CVD coating supported on the front surface of the base plate and defining a flat surface on which a masking pattern is to be formed, and a rear CVD coating formed on the rear surface of the base plate. The front and rear CVD coatings are made of a silicon compound. The ceramic membrane device is made by providing a plate having a flat front surface, a side surface and a rear surface, forming a front CVD coating made of a silicon compound on the side surface and the front surface of the plate, forming a rear CVD coating made of a silicon compound on a partial area of the rear surface of the plate so that an uncoated area remains, removing the portion of the plate corresponding to the uncoated area by means of etching so that the remaining portion of the plate can function as a circumferential frame for the ceramic membrane formed by the front coating.

摘要： A ceramic device is disclosed that has a silicon base plate, a first ceramic film formed on a first surface of the silicon base plate, a second ceramic film formed on a second surface of the silicon base plate opposite to the first surface, and an operation opening formed in the silicon base plate between the first and second surfaces. A surface portion of the first ceramic film exposed to the operation opening Is a mirror surface having 0.05 micrometers or less of center line average height Ra. A mirror surface keeping film can be formed between the first surface of the silicon base plate and the first ceramic film for keeping a mirror surface in an etching step to etch the silicon base plate, and the silicon base plate can be reduced partially in the etching step for forming an operation opening thereby exposing a corresponding portion of the mirror surface keeping film to the operation opening.

摘要： A power field effect transistor includes a bulge portion and/or a constricted portion in at least one of the heavily doped drain contact region and the lightly doped channel forming region, and heavily doped source regions are formed in the lightly doped channel forming region at intervals, wherein the avalanche breakdown takes place at the bulge portion and/or the constricted portion due to the concentration of electric field in the presence of excess voltage applied to the heavily doped drain contact region, and the breakdown current flows through the gaps between the heavily doped source regions so that a emitter-base junction of a parasitic bipolar transistor is not strongly biased.
