Title: Optical displacement detector
Inventor: KABAYA YOSHIHIKO
IPC: G01D5/36
Filed: 1987-11-18
Abstract: PURPOSE:To prevent that a part of illumination light is received by a light detecting element as disturbance light and to improve the S/N ratio of a detection signal, by reflecting illumination light by the reflecting mirror provided to a first member to allow the same to pass through a main scale and a reference scale. CONSTITUTION:The illumination light emitted from a light emitting element 24 is reflected by the second reflecting mirror 28A in a lens member 34 to become parallel light which in turn passes through a transmitting hole 30H in a light previous resin mold 32 to reach a reflecting mirror 28 through the first member 18. The illumination light reflected herein again passes through the member 18 to enter the resin mold 32 through a main scale 16, a reference scale 20 and the second member 22, and reaches the light detecting element 26 on a lead frame 30. By this constitution, the quantity of the illumination light reaching the element 26 increases and decreases repeatedly by the repetition of the superposition of the main scale 16 and the reference scale 20 corresponding to the relative displacement quantity of the members 18, 22 and the element 26 outputs the electric signal corresponding to the number of times of repetition to a measuring circuit 42 which in turn counts said signal to make it possible to output the same to a display device 44 as the relative displacement quantity of the members 18, 22.

Title: Semiconductor substrate
Inventor: MIYAJIMA MOTOMORI
IPC: H01L21/762
Filed: 1990-10-29
Abstract: PURPOSE:To prevent contamination of the substrate by dust produced by cutouts in the peripheral part of the device formation layer by coating the areas of the insulating film exposed along sides of the structure with a protective layer against hydrofluoric acid. CONSTITUTION:A SOI substrate 10 consists of a silicon device formation layer 13 formed on top of a SiO2 layer 12 on the surface of supporting layer 11 and of an anti-hydrofluoric acid protection layer 14, made for example of a polycrystalline silicone film, applied along the sides and bottom surface of the substrate. With this type of SOI substrate 10, in cases when a separate SiO2 film is layered on top of the formation layer 13 and this layer is etched with hydrofluoric acid, the SiO2 layer 12 formed on the supporting layer 11 is not etched by the hydrofluoric acid and unattached sections along the outer edge of the device formation layer 13 do not form. Therefore, if for example the SOI substrate 10 is stored in a quartz basket, even when a slight impact is applied to the sides of the device formation layer 13, the outer edge section does not chip.
