Abstract: PURPOSE:To prevent the leak of nongaseous gas by forming the seal part of a valve plate into a spherical shape, and ensuring a clearance rotatably in the linking part between an arm and the valve plate and moreover a clearance slidably in the linking part between the arm and a rotation shaft. CONSTITUTION:An arm 12 is rotated, and a valve plate 5 fitted to the tip of the arm 12 is pushed to an opening part. At that time, the plate 5 is moved in a direction to correct position displacement because a clearance DELTA1 is provided so that the plate 5 can be freely rotatable to the arm 12 onto the linking part between the plate 5 and the arm 12 and a clearance 2 is provided so that the arm 12 can be slidable in the axial direction of a rotation shaft 13 onto the linking part too between the arm 12 and a rotation shaft 13 even the position displacement of the plate 5 is caused to the opening part. Since the seal part 51 of the plate 5 is formed into a spherical shape even the tilt alpha of the plate 5 is caused to the opening part, the cross section of the plate 5 along the end part of the opening part becomes a circle always to surely shield the opening part to also any tilt alpha of the plate 5.

Abstract: PURPOSE:To prevent the disconnection of a wiring layer while holding moisture resistance by forming a first insulating layer onto a semiconductor substrate, smoothing a stepped difference section through the high-temperature heat treatment of the first insulating layer and forming a second insulating layer suitable for holding moisture resistance. CONSTITUTION:The insulating layer 5a is thermally treated at a high temperature to smooth the stepped difference section, and the insulating layer 8 having excellent moisture resistance is formed onto the insulating layer 5a. A hole 6a for contact with wiring is formed to a section required of a semiconductor element shaped onto the substrate 1. In this case, when the insulating layers 5a and 8 are oxide films, there is difference between both density because the layer 5a is thermally treated but the layer 8 is not so, and the opening section of the layer 8 is enlarged and the edge section of the hole 6a is smoothed even in case of either of wet or dry etching. Disconnection is not generated even when the wiring layer 7 is formed onto the layer 8.
