    摘要: A susceptor for use in a vertical vapor growth apparatus includes a susceptor body (12) having an upper surface, a plurality of wafer receiving portions (17) formed in the upper surface of the susceptor body (12), and plates (16) fixed in the upper surface of the susceptor body (12) near the wafer setting portions (17). The plates (16) have an upper surface such that, when wafers (5) are mounted in the wafer setting portions (17), the upper surfaces of the plates (16) and the wafers (5) are positioned substantially in the same plane. The plates (16) are made of quartz glass or fused silica.

    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: The susceptor according to the present invention comprises a main body in the shape of a trapezoidal plate, and which has three circular depressions formed in its surface. The main body is made of silicon carbide having a bulk density of 3.00 g/cm.sup.3 or more. At least 70% of the surface region of the main body is made of crystal particles having a diameter of 5 .mu.m or more. The main body has a thickness of, for example, 700 .mu.m. Six susceptors are attached to a hexagonal upper plate which is fastened to a shaft, and also to a hexagonal lower plate, thereby forming a barrel. Silicon wafers are placed in the circular depressions, so that single-crystal layers may be epitaxially formed on the wafers.
