Abstract: PURPOSE:To avoid gas pockets by a method wherein a dummy part is added to a U-groove and the dummy part form a crossing part or a large width part which has a larger aperture than the other part of the U-groove and chemical vapor deposition of filling material is carried out under depressurized conditions. CONSTITUTION:Even if polycrystalline silicon is made to grow on the other part of a U-groove, a cavity 20a remains at the center part of a dummy part 22c. If chemical vapor phase deposition is continued in this state, growth gas, for instance SiH4, is made to flow into a tunnel cavity 20b in the part other than the dummy part 22c from the cavity 20a at the center part of the dummy part 22c to fill the cavity 20b with polycrystalline silicon. Although the cavity 20a is not yet completely filled when the cavity 20b is completely filled with polycrystalline silicon, the chemical vapor phase deposition is discontinued at this stage. If Al is applied like conventional examples and patterned, an Al dot 18b is left between electrode wirings 18. However, the Al dot 18b does not cause the short-circuit between the electrode wirings 18.

Filed: 1978-02-10
Abstract: PURPOSE: To permit a reasonable control for thyristor group by making a cascade connection of plural thyristors on the DC output side so that the DC output voltage of thyristor is not rapidly changed immediately after part of the thyristor group is switched to by-pass pair operation.  
     CONSTITUTION: A cascade connection is made for the plural thyristor groups TH1 and TH2 on the DC side and thereby the ignition phase of thyristor in the thyristor groups is separately controlled to supply DC voltage to the load L. By applying the detected voltage Vo corresponding to the DC output voltage Vdc to the current controller 11, the signal e 3  corresponding to the deviation e i  between the current  standard signal i 0  and the current detected signal i 1  is applied to the thyristor  through the gat pulse distributor 5 when a switching command for by-pass pair operation is applied, and thus the rapid change of the output voltage Vdc can be prevented. For this reason, the detected voltage Vo corresponding to the output voltage Vdc is applied to the terminal T 1  and the early value is set up to the DC output voltage immediately before the application of the switching command BPP.
