Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To make possible even the superfine processing of elements, by applying high frequency bias voltage to a sample stage independently of generation of plasma, and controlling the ON/OFF of the high frequency bias voltage which is larger than continuous high frequency bias voltage which can provide the same etch rate. SOLUTION: While microwaves are generated into a vacuum container 104 from a magnetron 101, etching gas such as halogen is also introduced into the container. In the vacuum container 104, plasma of the etching gas is generated with the introduction of microwaves. At the same time with introduction of microwaves, the gas pressure is kept constant and microwave power is also supplied continuously and high frequency bias applied to a sample stage is cyclically turned ON and OFF. By turning the high frequency bias ON and OFF, the energy of ions for obtaining the same etch rate for polisilicon can be set high and anisotropy is eliminated. For example, Vpp with continous bias 60 W is 320 V and Vpp with ON/OFF bias peak power 300 W is 1410 V.

Title: Voltage controlled oscillator
Inventor: KUBO KUICHI
IPC: H03B5/12
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a voltage controlled oscillator which uses a voltage variable capacity element applying a MOS(metal oxide semiconductor) that has a large capacity change when the voltage is set of a low level. SOLUTION: A voltage controlled oscillator which varies the oscillation frequency of an oscillation circuit 2 by a voltage variable capacity element uses a MOS element 4 whose gate-source electrostatic capacity varies in steps based on the threshold voltage against the DC voltage that is applied between a gate and a source. Then the sine wave-shaped oscillation voltage generated by the circuit 2 and the DC voltage are applied between the gate and the source. Thus, an operating area Δθ (rad) which exceeds the threshold voltage of a single cycle of the oscillation voltage is controlled by the DC voltage.  At the same time, the distortion oscillation current that is generated between the gate and the source with the area Δθ defined as its passing area is also controlled to vary the basic wave component of the distortion oscillation current to the oscillation voltage. As a result, the substantial gate-source capacity is varied to the basic wave component.
