Abstract: In a semiconductor device formed on a silicon surface which has a substantial (110) crystal plane orientation, the silicon surface is flattened so that an arithmetical mean deviation of surface Ra is not greater than 0.15 nm, preferably, 0.09 nm, which enables to manufacture an n-MOS transistor of a high mobility. Such a flattened silicon surface is obtained by repeating a deposition process of a self-sacrifice oxide film in an oxygen radical atmosphere and a removing process of the self-sacrifice oxide film, by cleaning the silicon surface in deaerated H2O or a low OH density atmosphere, or by strongly terminating the silicon surface by hydrogen or heavy hydrogen. The deposition process of the self-sacrifice oxide film may be carried out by isotropic oxidation.

Abstract: In a jitter generator (phase modulator), worsening of phase noise is restrained and phase modulation accuracy is improved, and the phase modulation accuracy is improved by preventing a change in the detection sensitivity of the phase detector, if any, from affecting a change in the phase modulation index. Also, phase modulation is made possible without lowering the phase modulation accuracy even when an input phase signal increases. In a jitter generator using a PLL circuit, a quadrature modulator to which a modulation signal from a phase signal generator is provided is inserted to an input stage of a phase detector that constitutes the PLL circuit.

Abstract: The present invention provides a semiconductor device and a method of manufacturing the same improved in reliability of a gate insulating film by increasing a total charge amount Qbd by suppressing a film stress of a gate electrode formed of a polysilicon film, to a low value. Since the film stress is closely related to a film formation temperature, it is possible to reduce the film stress lower than the conventional case by forming a film at as a high temperature as 640° C. or more. At this time, when the film stress decreases, the total charge amount Qbd regulating dielectric breakdown of the film increases, improving reliability of the gate insulating film. It is therefore possible to set the film stress of the gate electrode at 200 MPA or less in terms of absolute value by forming the gate electrode at 640° C. or more.
