An orifice changeable pressure type flow controller capable of easily changing a control flow by easily changing an orifice without disassembling and assembling the flow controller. In the flow controller (A), the valve body (23) of a control valve (2) is disposed between an inlet side mounting block (39) having a connection part for a fluid feed pipe and an outlet side mounting block (43) having a connection part for a fluid takeout pipe, and the fluid inlet side of the valve body (23) is releasably connected airtight to the inlet side mounting block (39) and the fluid outlet side of the valve body (23) is releasably connected airtight to the outlet side mounting block (43) to form a flow passage allowing gases to flow therein through the control valve (2). The gasket type orifice (38) of the flow controller (A) is detachably inserted between a gasket type orifice insertion hole (42c) formed on the outlet side of the valve body (23) and a gasket type orifice insertion hole (43b) in the outlet side mounting block (43).

A device for plasma processing comprises a gas supply system for supplying a source gas necessary for creating a plasma, and an exhaust system for discharging the gas to reduce the pressure in a container, in which a plasma is generated to process an object. The container encloses a conducting stage for supporting an object to be processed, and the stage has a structure to which DC or high-frequency voltage is applied. The stage includes the cooling channel within it to cool the object to be processed. The material of the cooling channel has a high thermal conductivity to transfer heat from the stage to the cooling channel, and the material is highly insulative to isolate the coolant from the DC or high-frequency voltage is applied to the stage.

[PROBLEMS] To provide a semiconductor storage device having excellent electrical characteristics (writing/erasing characteristics) by excellent nitrogen concentration profile of a gate insulating film and to provide a method for manufacturing such device. [MEANS FOR SOLVING PROBLEMS] In a semiconductor device manufacturing method relating to a first embodiment of this invention, a method for manufacturing a semiconductor storage device which operates by transferring charges through a gate insulating film formed between a semiconductor substrate and a gate electrode includes a process of introducing oxynitriding species previously diluted by using a gas for plasma excitation into a plasma processing apparatus, generating the oxynitriding species by plasma, and forming an oxynitride film on the semiconductor substrate as the gate insulating film. The oxynitriding species contain an NO gas of 0.00001-0.01% to the total gas quantity introduced into the plasma processing apparatus.

A semiconductor device exhibiting good characteristics by sustaining the dielectric constant of a High-K insulating film in a high state, and a process for fabricating a semiconductor device in which the dielectric constant of the High-K insulating film can be sustained in a high state. The semiconductor device comprises a silicon substrate, a gate electrode layer, and a gate insulating film interposed between the silicon substrate and the gate electrode layer. The gate insulating film is a high dielectric constant (high-k) film produced by nitriding a mixture of a metal and silicon. Since the High-K film itself is a nitride, generation of SiO2 can be prevented.

A microwave plasma process device, wherein a metal lattice-shaped shower plate (111) is provided between a dielectric shower plate (103) and a substrate (114), and a plasma exciting gas mainly consisting of rare gases and a processing gas are released from different locations. When the lattice-shaped shower plate is grounded, a high-energy ion can be implanted into the surface of the substrate (114). When the thicknesses of a dielectric partition (102) at a microwave introduction portion and an dielectric are optimized to maximize a plasma exciting efficiency, and, at the same time, the distance between a slot antenna (110) and the dielectric partition (102) and the thickness of the dielectric shower plate (103) are optimized, a high-power microwave can be input.
