Title: Device for measuring compound component ratio
Inventor: HABU TOSHIYA
IPC: H01L21/66
Filed: 1993-08-25
Abstract: PURPOSE:To precisely detect the composition of a compound semiconductor without interrupting an ion injection process and diffusion process and damaging a sample by irradiating the surface of the sample with a probe light and modulation exciting light one over the other so as to detect the reflection spectrum of the surface of the sample synchronizing with the modulation. CONSTITUTION:An exciting light is modulated by a chopper 2 and the surface of a sample 5 is irradiated with the modulation exciting light, then the same irradiation point is irradiated with a white light P. The reflecting light H is detected spectroscopically by a spectroscope 6 and detector 7, and a photo-reflectance DELTAR is picked up, then, after it is standardized by the direct current element R of the reflecting light, the result is detected through scanning detection using the selected wavelength of the spectroscope 6 to obtain its photo-reflectance spectrum. Its wavelength at the peak is equivalent to the absorption edge wavelength of the chemical semiconductor, so the absorption edge energy is calculated from the result. Furthermore, a metering line in which the correlation between the absorption edge energy of substance and the chemical semiconductor composition ratio is established is stored in a data storage part 11 and it is compared with the absorption edge energy in an operation control part 10, so that the composition ratio can be obtained.

Filed: 1986-09-08
Abstract: PURPOSE:To enhance measuring accuracy, by simplifying an excessive pressure protective mechanism to reduce the amount of a sealing liquid and reducing the variation of a zero point due to temp. caused by the temp. volumetric expansion of the sealing liquid. CONSTITUTION:The chamber 11 provided in a main body 1 is divided into pressure receiving chambers 12, 13 by a center diaphragm (SDP)2. Whereupon, when the measuring pressures P1, P2 of the receiving chambers 12, 13 are within a measuring range, SDP2 does not displace because of the attraction force of the first ring 32 composed of a permanent magnet and the differential pressure of said measuring pressures is detected by a differential pressure detection mechanism 5. When the measuring pressure P1 of the pressure receiving chamber 12 exceeds the measuring range to reach a predetermined value, a plate 33 moves along with the diaphragm 2 and the large flow of a sealing liquid 101 generates to continue until a sealing diaphragm (DP)41 closely contacts with the main body 1 and, thereafter, the pressure of the pressure receiving chamber 12 does not rise and the ring 32 does not move. When the measuring pressure P2 of the pressure receiving chamber 13 exceeds the measuring range to reach the predetermined value, the flow of a sealing liquid 102 generates until DP42 closely contacts with the main body 1 in the same way as mentioned above and, after the close contact of DP42, the pressure of the pressure receiving chamber 13 does not rise.

Title: Manufacture of semiconductor device
Inventor: YAMAGISHI MACHIO
IPC: H01L29/417
Filed: 1982-12-02
Abstract: PURPOSE:To contrive to increase the integration and reduce the number of processes by a method wherein a nitride layer is formed on a semiconductor substrate, while a semiconductor layer of a fixed shape is formed thereon, an oxide layer is formed on the exposed surface of the semiconductor layer, the nitride layer is selectively removed with the oxide layer as a mask, and impurity introduction and/or electrode formation is performed to the surface of the exposed semiconductor substrate. CONSTITUTION:When the entire element is left as it is in an oxidizing atmosphere, the film thickness thereof itself does not increase on a source and a drain region because of the presence of a nitride film 10. On the other hand, an SiO2 film 15 grows in the periphery of a polycrystalline Si 14 which forms a gate electrode. Thereafter, when the entire surface of the element is placed in an etching atmosphere, the gate electrode 14a itself is maintained in the state of being covered with an insulator even at the time of the exposure of the surface of the Si substrate 1 on the source and drain regions, since the film thickness of the SiO2 film 15 is sufficiently thicker than that on the source and drain regions. Afterwards, a source and a drain 16 and 17 are formed by diffusing or ion-implanting an N type impurity. Metallization is performed thereat, and a source and a drain electrode 18 and 19 are adhered thereon.
