Patent JP-S62165390-A (JP)
Title: Semiconductor laser
Inventor: SUGIMOTO MITSUNORI
IPC: H01S5/00
Filed: 1986-01-16
Abstract: PURPOSE:To obtain a semiconductor laser with a low threshold current by providing impurity introduced regions which suppress a leakage current. CONSTITUTION:First, a p-type cladding layer 2, an active layer 3, an n-type cladding layer 4 and an n-type cap layer 5 are formed on a p-type GaAs substrate 1 by crystal growth. After a crystal growth, a mesa stripe 6 is formed by photoetching and then Zn diffused regions 10 are formed by selective diffusion. Then an SiO2 film 7 is formed and the SiO2 film on the mesa stripe 6 is removed by photoetching and, after that, an n-type electrode 8 and a p-type electrode 9 are formed to complete the process. Then a pellet is cut out by cleaving and mounted on a heat sink and lead wires are attached. The active layer 3 beneath the mesa stripe 6 functions as a main light emitting region. As the SiO2 film 7 is formed on the part other than the mesa stripe 6, a current is concentrated to the mesa stripe 6. The current injected from the mesa stripe 6 tends to spread to the horizontal direction in the n-type cladding layer 4 but, as the Zn diffused regions 10 are provided, a leakage current which flows horizontally over the regions 10 hardly exists.

Title: Semiconductor integrated circuit device
Inventor: AKIMOTO KAZUYASU
IPC: G11C11/00
Filed: 1989-01-16
Abstract: PURPOSE:To contrive to allow a digital system to have a high performance by setting plural random access memories to an operating state in order from that which is placed adjacently to an input buffer. CONSTITUTION:Random access memories RAM 1-5 are set to an operating state in order from that which is placed adjacently to an input buffer IB due to a fact that address signals A0-Ai are delayed successively and formed by repeating buffers RB1, 2. An output data selecting circuit DSL contains plural stages of logic circuits, and an output signal is inputted in order from an output signal of the random access memory placed separately from the circuit DSL. As a result, a variance of a transfer delay time until a read-out signal of each memory RAM is secured in an output terminal of the circuit DSL after the signals A0-Ai are inputted is compressed, while being averaged. In such a way, an access time of an Application Specific Integrated Circuits memory is shortened equivalently, by which it is promoted to allow a digital system to have a high performance.

Filed: 1993-01-20
Abstract: PURPOSE: To provide a thin plate reinforcing laminated body which is useful for deforming a reinforcing layer by conforming to a shape of a thin plate and useful for restraining strain of the reinforcing layer. CONSTITUTION: A thin plate reinforcing laminated body 2 consists of an adhesive layer 3 and a reinforcing layer 4. The base material of the adhesive layer 3 is of epoxy resin. The reinforcing layer 4 is formed by impregnating a thermoplastic resin (rigid vinyl chloride resin) to be a matrix 40 into a reinforcing material 43 (glass cloth). A Tg temperature of the thermoplastic resin is higher than a use temperature area of a thin plate 1 i.e., a room temperature area, and lower than the curing temperature area of the adhesive layer 3. To a rear face 1a of the thin plate 1 having a curved face formed by press molding, the laminated body 2 is adhered and heated. When the adhesive layer 3 is cured, the matrix 40 is softened, so that the reinforcing layer 4 becomes deformable by conforming to the curved face of the thin plate 1.  When heating treatment is finished, the matrix 40 is cooled and cured.

IPC: H01L21/31
Filed: 1987-01-16
Abstract: PURPOSE:To obtain a uniform thin film in the formation of a thin film using a soft landing furnace by inserting a wafer into a furnace at a first temperature, and forming the film in the furnace at a second temperature higher than the first temperature. CONSTITUTION:When a thin film is formed by a soft landing furnace, a wafer is inserted into the furnace at a first temperature T1, and the film is formed in the furnace at a second temperature T2 higher than the temperature T1. For example, the wafer is inserted at temperature T1 sufficiently lower than the oxidizing temperature of the wafer, and substitution gas is filled in the furnace. Thereafter, it is heated to a wafer reaction temperature T2, and reaction gas is fed to form a thin film. After the film is formed, substitution gas is again filled in the furnace, and the wafer is removed at sufficiently lower temperature T3 than the oxidizing temperature. Thus, the uniform thin film can be obtained without oxide film of irregular thickness due to oxygen contained in the atmospheric air to be introduced by inserting the wafer into the soft landing furnace.
