Title: Method for retrieving appropriate heating condition at connection of optical fiber
Inventor: WATANABE TSUTOMU
IPC: G01K11/06
Filed: 1989-07-31
Abstract: PURPOSE:To easily obtain the appropriate heating conditions of optical fibers by regulating a discharge current in accordance with the way how the ends of the optical fibers melt. CONSTITUTION:The end face of the optical fiber 1 is positioned between a pair of discharge electrodes 3. This end part of the optical fiber 1 is melted by electric discharge heating and whether the discharge heating conditions of the end part of the optical fiber are suitable or not is discriminated by the distance DELTAL1 at which this end face retreats. Namely, the fusion splicing of the optical fibers is previously executed and a number of the retreat distances DELTAL1 when the permissible connection loss is obtd. are determined and the max. value among these distances is designated as Lmax and the min. value as Lmin. The end part of the optical fiber is melted and the retreat distance DELTAL1 is determined prior to the fusion splicing of the optical fibers. The discharge current is then so regulated that this retreat distance DELTAL1 is maintained at >=Lmin and <=Lmax. The appropriate heating conditions are easily obtd. in this way.

Title: Heat treatment for compound semiconductor
Inventor: EHATA TOSHIKI
IPC: H01L21/318
Filed: 1982-11-12
Abstract: PURPOSE:To enable heat treatment for compound semiconductor by usual electric oven by using complex film of Si3N4 and SiO2 as a protective film for heat treatment. CONSTITUTION:In GaAs substrate, an Si implantation layer is selectively arranged and SiO2 film is evaporated on surface of the substrate by vacuum evaporation and Si3N4 film is laminated by CVD method. After that, annealing is done in N2 at 800 deg.C followed by removing Si3N4/SiO2 film by buffer solution of hydrofluoric acid and then ohmic electrode is applied. By this constitution, there is no crack produced in Si3N4/SiO2 film after annealing and surface of the crystal after the removal maintains its mirror surface before annealing and variability of characteristics is reduced. This constitution enables heat treatment with use of usual electric oven being used for, for example, heat oxidation of Si element, resulting in mass production. In addition, heat treatment in V group or VIgroup gas is unnecessary thereby improving safety and sanitation as well as the characteristics of the device.
