Title: Semiconductor optical switch
Inventor: AJISAWA AKIRA
IPC: G02F1/015
Filed: 1988-12-23
Abstract: PURPOSE:To make an electric field and waveguide light overlap sufficiently with each other and to improve the performance of a device by converging an electric field distribution on an optical waveguide. CONSTITUTION:When the light from a light source is made incident on the part of the optical waveguide of a guide layer 3, the incident light is projected as it is. Then when a reverse bias voltage between a p-side electrode 5 and a n-side electrode 6 is applied, a depletion layer applied with the electric field spreads toward the guide layer from the interface between a clad layer 4 and the guide layer 3 and the electric field is applied to the optical waveguide. Consequently, the band gap of an InGaAsP layer spreads toward a long-wavelength side by Franz-Keldysh effect, so that the incident light is absorbed and modulated. At this time, the depletion layer spreads to the projection part of a substrate 1 with a voltage of about 1V and when the voltage is raised after the depletion layer reaches through the projection part, the intensity of the electric field in the optical waveguide increases, so that the quenching ratio of the waveguide light also increases. At this time, an area where the electric field is applied is converged on between the projection part of the substrate 1 and the p-n junction interface between the clad layer 4 and guide layer 3, so that the area overlaps with the waveguide light by almost 100%.

IPC: H01L21/336
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To realize a short channel MOS transistor without causing the decrease of ON current of an MOS transistor. SOLUTION: Side wall oxide silicon films 14 are formed on only the side wall parts of source region sides of an NMOS gate electrode 9 and a PMOS gate electrode 10. On the upper part of a drain region, an oxide silicon film 13 is left as it is. After that, a source.drain region is formed by using an ion implantation technique. Since the oxide silicon film 13 does not exist on the upper parts of a source N<+> region 16 and a source P<+> region 18, the junction of diffusion layers of the source N<+> region 16 and the source P<+> region 18 becomes deeper than that of a drain N<+> region 15 and a drain P<+> region 17.

Title: Membrane multilayer structure
Inventor: SAKATA SHOJI
IPC: B32B3/02
Filed: 1990-11-30
Abstract: PURPOSE:To form a thick multilayer film by forming the first film layer on a substrate and subsequently forming many film layers so that the end surfaces of film layers on and after the second film layers are successively retracted from the end surfaces of the previous film layers to be formed in a stepped state to relax the interfacial stress between the substrate and the film layers at the end part of the substrate. CONSTITUTION:When film end parts are shifted to be formed in a stepped state, film thickness becomes only the thickness of one membrane in an interfacial end part (a) where the concn. of stress is most marked and, therefore, the rigidity of a membrane is extremely low and the stress of the interfacial end part is suppressed low. Since the acting point of the force of the second layer exerted on the first layer is shifted from the part directly above the interfacial end part (a), the stress at the point (a) due to said force must be reduced. When the shift quantity of the next layer to the previous layer is set to film thickness or more, sufficient stress reducing effect is obtained and, therefore, it is unnecessary to set a strict dimension and correspondence is taken by adjusting a mask at the time of film formation.
