Abstract: PURPOSE:To eliminate generation of cracks in a thin film at the time of transporting a semiconductor wafer to be treated and thereby to reduce amount of generated waste by holding edge part of the semiconductor wafer to be treated and the holding plate edge therefor in a non-contact state. CONSTITUTION:A supporting pedestal is mounted on a rotary shaft arranged nearly at a central part of a reaction vessel and a holding plate is fixed thereon. The edge part of the semiconductor wafer to be treated and the holding plate edge therefor are held in the non-contact state. A terminal electrically connected to an execution is provided at the reaction vessel. A plate member in the reaction vessel is made to function as a cathode and bias is impressed thereon. A rotatable plate target is disposed corresponding to the plate member. A magnet is arranged adjacent to the target.

Filed: 1981-06-22
Abstract: PURPOSE:To eliminate the instability of the initial arc and to improve arc starting ability and weldability by specifying the compsn. of the material at the leading end of a low hydrogen type coated electrode and controlling the grain sizes  of the iron powder compounded therewith. CONSTITUTION:A coating material contg., by weight, 30-70% iron powder, 8- 15% graphite, 20-60% manganese dioxide, 0.2-4% binder, and contg. 8-20% water glass in terms of solids based on the total weight of the above-described components is coated at the leading end of a low hydrogen type coated electrode. The iron powder of the grain size constitution wherein <=74mum particles are contained at >=70wt% based on the total weight of the iron powder is compounded. The reason for specifying the component compsn. of the coating material at the leading end lies in that if the iron powder is compounded too much, the initial arc is not stabilized and blow holes are generated. If the graphite is compounded too much, the content of carbon increases and crack resistance decreases.
