Process temperature is above 350° C., at a pressure of about 2.5 torr. Any hydrogen present in the resulting silicon nitride film is bound by N—H bonds rather than Si—H bonds, and is thus more strongly bound to the film.

First electrodes of the first and second capacitors are connected in common, a first voltage (½ VPERI) is applied to the first electrodes, a second voltage (for example, VPERI) that is different from the first voltage is applied to either one of the second electrodes, and the first voltage is applied to the other second electrode. A capacitor which constitutes a dummy capacitance is provided by applying one of the second electrodes of the first and second capacitors with the same voltage as the voltage applied to their first electrodes, whereby making it possible to increase the area of the compensation capacitance in the semiconductor device without changing a specified capacitance value.

  • Publication number: 20130002338
    Abstract: SOI MOSFETs are used for the transistors for switching of an antenna switch and yet harmonic distortion is significantly reduced. Capacitance elements are respectively added to either the respective drains or gates of the transistors comprising the through MOSFET group of reception branch of the antenna switch. This makes the voltage amplitude between source and gate and that between drain and gate different from each other. As a result, the voltage dependence of source-drain parasitic capacitance becomes asymmetric with respect to the polarity of voltage. This asymmetry property produces signal distortion having similar asymmetry property. Therefore, the following can be implemented by setting it so that it has the same amplitude as that of second-harmonic waves arising from the voltage dependence of substrate capacitance and a phase opposite to that of the same: second-order harmonic distortion can be canceled out and thus second-order harmonic distortion can be reduced.

  • Publication number: 20120326270
    Abstract: A metal capacitor structure includes a plurality of line level structures vertically interconnected with via level structures. Each first line level structure and each second line level structure includes a set of parallel metal lines that is physically joined at an end to a rectangular tab structure having a rectangular horizontal cross-sectional area. A first set of parallel metal lines within a first line level structure and a second set of parallel metal lines within a second line level structure are interdigitated and parallel to each other, and can collectively form an interdigitated uniform pitch structure. Because the rectangular tab structures do not protrude toward each other within a region between two facing sidewalls of the rectangular tab structures, sub-resolution assist features (SRAFs) can be employed to provide a uniform width and a uniform pitch throughout the entirety of the interdigitated uniform pitch structure.
