Through this etching process, holes or grooves achieving a high aspect ratio are formed in a desirable shape at the silicon layer.

    摘要: A Si etching method etches a Si wafer held on a susceptor placed in a processing vessel by a plasma-assisted etching process. A mixed etching gas prepared by mixing fluorosulfur gas, such as SF6 gas, or fluorocarbon gas, O2 gas and fluorosilicon gas, such as SiF4 gas is supplied into the processing vessel. RF power of 40 MHz or above is applied to the mixed etching gas to generate a plasma. The Si wafer is etched with radicals and ions contained in the plasma.

    摘要: A press-forming mold has a protective film for preventing seizing during press-forming formed on at least a forming surface that comes into contact with a formed body. The protective film is formed by PVD. An arbitrary selection section extracted from the surface of the protective film is divided into a plurality of individual sections; and, when the gradient of the surface at the nth division point is represented by (dZn/dXn), taking N to represent the number of divisions, the root-mean-square RΔq calculated by the following numerical expression is no greater than 0.032. R ⁢ ⁢ Δ ⁢ ⁢ q = 1 N ⁢ ∑ n = 1 N ⁢ ⁢ ( d ⁢ ⁢ Z n d ⁢ ⁢ X n ) 2 It is thereby possible to improve the seizing resistance of a press-forming mold having a protective film formed by PVD.

    摘要: In a transparent electroconductive film including a transparent substrate and a transparent electroconductive oxide layer disposed on the transparent substrate, when the transparent electroconductive oxide layer is composed of zinc oxide, the surface resistivity of the transparent electroconductive oxide layer increases with time and thus it has been difficult to obtain a transparent electroconductive film stable against an environmental variation. Consequently, hard carbon films are provided on the surfaces of a transparent electroconductive oxide layer including at least one layer and containing zinc oxide as a main component in “the order of transparent substrate-hard carbon film-transparent electroconductive oxide layer-hard carbon film” or “the order of hard carbon film-transparent substrate-transparent electroconductive oxide layer-hard carbon film”. Alternatively, an organosilicon compound covering layer is provided on a surface of the transparent electroconductive oxide layer. Thereby, the water contact angle can be 75 degrees or more, and an increase in the resistivity of the transparent electroconductive oxide layer can be suppressed.
