Abstract: PURPOSE:To provide a suction casting device which can maintain the inside part of an air-permeable casting mold at a prescribed degree of evacuation and can assure satisfactory run of molten metal by providing to the upper exposed part of the casting mold a hermetic sealing material of which the part facing the sprue part is melted or dissipated by heating. CONSTITUTION:An air-permeable casting mold 12 and an upper molding flask 13 as well as an air-permeable casting mold 14 and a lower molding flask 15 are stacked on a suction box 16, and a sprue part 12a and a sprue hole 22a are positioned to the top surface of the mold 12 and the flask 13. A heat-resistant rubber plate 22 is installed. A resin film 23 is placed on the plate 22 and is pressurized and fixed by a seal ring 24 to seal the entire part of the casting mold hermetically. The inside of the box 16 and the molds 12, 14 is evacuated through a suction pipe 17. After it is confirmed that the inside of the molds 12, 14 attains a prescribed degree of evacuation, the separately prepared molten metal is charged toward the sprue part 12a. The film 23 covering the part 12a is immediately gassified and scattered by the contact with the molten metal in this stage; therefore, the inflow of the molten metal is not hampered. The molten metal is packed to each corner in the mold cavity 14a while the part 12a is filled instantaneously with the molten metal with practically no change in the degree of vacuum during the charging.

Abstract: PURPOSE:To sediment a deposite onto a wafer without generating a defect in the wafer by applying voltage optimum for capturing electrons to a shutter for capturing electrons. CONSTITUTION:In a vacuum vessel 1, the shutter 6 is brought to a closed state, a wafer support base 4 is brought to ground potential, and DC negative voltage is applied to a target support base 5. Accordingly, argon ions Ar<+> are sputtered, and atoms, aluminum Al and silicon Si in a target material are induced out while moisture and an adsorbed gas adhering on the surface of the target material are removed. When moisture and the adsorbed gas are removed, ground or positive voltage is applied to the grid-shaped shutter, and the shutter 6 is brought to an opened state, thus capturing electrons generated when argon Ar atoms are ionized by the grid-shaped shutter 6. Al and Si atoms induced out by sputtering Ar<+> deposit on the silicon wafer disposed to the wafer support base 4 at the same time, and an Al film containing Si is formed.
