    摘要: In one embodiment of the present invention, a power IC device is disclosed containing a power MOS transistor with a low ON resistance and a surface channel MOS transistor with a high operation speed. There is also provided a method of manufacturing such a device. A chip has a surface of which the planar direction is not less than −8° and not more than +8° off a silicon crystal face. The p-channel trench power MOS transistor includes a trench formed vertically from the surface of the chip, a gate region in the trench, an inversion channel region on a side wall of the trench, a source region in a surface layer of the chip, and a drain region in a back surface layer of the chip. The surface channel MOS transistor has an inversion channel region fabricated so that an inversion channel current flows in a direction not less than −8° and not more than +8° off the silicon crystal direction.

    摘要: A plasma processing apparatus in which consumption of expensive krypton and xenon gases is suppressed as much as possible while reducing damage on a workpiece during plasma processing. In plasma processing of a substrate using a rare gas, two or more kinds of different rare gases are employed, and an inexpensive argon gas is used as one rare gas and any one or both of krypton and xenon gases having a larger collision cross-sectional area against electron than that of the argon gas is used as the other gas. Consequently, consumption of expensive krypton and xenon gases is suppressed as much as possible and damage on a workpiece is reduced during plasma processing.
