Title: Manufacture of semiconductor device
Inventor: EMA TAIJI
IPC: H01L21/324
Filed: 1981-03-20
Abstract: PURPOSE:To form nondefective regions at the shallow layer regions of a semiconductor substrate without giving damage to a crystal surface by a method wherein thermal treatment is applied to the semiconductor substrate under NH3 atmosphere. CONSTITUTION:A thermal treatment process is divided into three. The first process is executed at relatively high temperatures, for example, at 1,100- 1,200 deg.C and the density of impurities such as oxygen O or the like at the shallow layer of a substrate is decreased and a stable nitride films 3 are also  formed on the surfaces of the shallow layers of the substrate to prevent the substrate from damage at the following high-temperature processes. The second process is executed at relatively low temperatures, for example, at 800 deg.C and a crystal defect is generated at the deep layer of the substrate by serving impurities such as oxygen O or the like as a nucleus. The third process is performed at high temperatures, for example, at 1,200 deg.C and nondefective regions 1 are formed at the shallow layers of the substrate by centering around the crystal defect by gettering effect.

In addition, the temp. and pH of the electrolyte are confined within the area in the figure enclosed with point A (30 deg.C, pH13), point B (30 deg.C, pH9), point C (55 deg.C, pH6.5), and point D (55 deg.C, pH13), where the point on the line of 55 deg.C and pH13 is excluded. The pH is adjusted by adding NaOH, etc. By this method, cupric oxide powder capable of being easily filtered, precipitated, and separated is formed, and the powder is filtered, dried, and recovered. Since the electrolytic temp. is held at <55 deg.C, an inexpensive electrolytic cell of PVC can be used.

Filed: 1989-02-22
Abstract: PURPOSE:To prevent an optical fiber from deteriorating caused by thermal influence by allowing a coil made of shape memory alloy to extend/contract by utilizing the thermal influence upon the internal wall of a protection tube depending upon the distance between a lens and an optical fiber, and moving the lens automatically. CONSTITUTION:The optical fiber 1 extends thermally with a laser input and then the distance L between the end surface of the optical fiber 1 and the lens 3 is reduced, but the inside of the protection tube 6 is irradiated directly with laser beam because of the divergence angle of the laser beam and reflected light from the lens 3 is abutted on the inside of the protection tube 6 without entering the end surface of the optical fiber 1, so that the temperature rises. Then its heat is conducted to the coil spring 8 through the protection tube 6, the spring 8 is contracted by shape memory deformation to shorten the distance L between the end surface of the optical fiber 1 and the lens 3, and no laser beam, therefore, is abutted on the inside of the protection tube 6, thereby preventing the rise of temperature in the protection tube 6.

Filed: 1983-03-15
Abstract: PURPOSE:To calculate the optimum control value that is accordant with the actual object process characteristics by controlling the weight at a working field in response to the dynamic responsiveness of the object process. CONSTITUTION:The dynamic response is calculated for each part of an object process 1 which received a command from a control setting/changing part 2 which gives a process dynamic response to decide the weight. Then the time series data is stored in a memory part 3, and the control deviation value and the manipulated variable which are related to decide the weight are shown in a diagram in terms of time series out of the data stored in the part 3. At the same time the present set weight is displayed on the screen of a CRT4. Looking at this display, a setting/changing part 5 increases (decreases) the weight of the control deviation value or the manipulated variable that has an extraordinary large (small) amount of variation. Then an optimum control value calculating part 6 performs a matrix operation to minimize the control index. A control part 7 calculates the optimum manipulated variable from the optimum control value.
