Patent JP-H07211921-A (JP)
Title: Manufacture of semiconductor element
Inventor: TEI HEIKOU
IPC: H01L23/29
Filed: 1994-12-28
Abstract: PURPOSE: To enhance the effect of hydrogenation by conducting heat treatment for the hydrogenation by using a capping layer having a low hydrogen diffusion coefficient in a process of the hydrogenation wherein a plasma nitride is used. CONSTITUTION: After a plasma nitride layer 11 is formed on the upper side of a layer wherein a fundamental structure of a transistor is formed, a capping layer 12 is formed on the upper side thereof. Then, heat treatment is conducted so that hydrogen may be produced from the plasma nitride layer 11 and diffused into the fundamental structure of the transistor. When plasma silicon (a-Si;H) of which the hydrogen diffusion coefficient is small is used as the capping layer 12, a large number of dangling bonds are produced and these become effective barriers to outward diffusion of the hydrogen and function also as hydrogen producing sources. By conducting the heat treatment for diffusion of the hydrogen after the capping layer 12 is formed, the hydrogen produced from the plasma nitride 11 scarcely escapes outside and it is diffused and gets into the transistor.  Thus, the effect of hydrogenation can be enhanced.

IPC: F24H1/18
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent an electric water heater from becoming incapable of heating to supply hot water by a fault caused by a lapse of its lifetime of a component by warning the effect in the case of the lapse of an accumulated using time by comparing the using time with its lifetime of the each component so that the using time exceeds its lifetime. SOLUTION: At the time of finishing supply of a midnight power, an accumulated using time of each component stored in a cumulative memory means is increased by one day. Thereafter, the accumulated using time (number of days) is compared with a lifetime of each component stored in a component lifetime memory means, and when the using time exceeds the lifetime, a predetermined lamp provided on an operation panel of the electric water heater is lit to warn an arrival of the lifetime of the component to a user. The user communicates the arrival of the lifetime of the corresponding component to a repairman, who provides the component, and then replaces the component. Thus, stop of the heater by the fault caused by the lapse of the lifetime of the component can be prevented.

Abstract: PURPOSE:To improve the freedom degree of a data pattern at a low cost and at the same time to measure the number of bit errors at a high speed by preparing a memory to store the write data, a data driver circuit, a comparator, a control processor, etc. CONSTITUTION:The data pattern to be written into a test device 1 is written into a COMPARE data memory 4 via a bus transceiver 5 and then into the device 1 via the transceiver 5 and an I/O 2. While the read data is written into a READ data memory 3 via the I/O 2 and at the same time compared with the data on the memory 4 via a comparator 6. In this case, the control is carried out so that the read data and the data on the memory 4 are not set on the same signal line. The comparator 6 compares the byte data with each other to output the coincidence and the discordance for each bit. A byte bit arithmetic unit 7 calculates the number of discordant bits and sends this calculating result to a control processor 9 via a bus transceiver 8. Thus it is possible to improve the freedom degree of the data pattern at a low cost and to measure the number of bit errors at a high speed.

Abstract: PURPOSE:To enable a semiconductor laser to be packaged on a coplanar trans mission line by forming two mesa structure exposing a parallel striped (111) A plane and the other directional surface. CONSTITUTION:Within the title manufacturing method, the striped part of an InP cap layer 7 beneath an SiO2 mask 8 takes an inverse mesa shape exposing (111) A plane.
