摘要:
A dielectric film wherein N in the state of an Si3=≡N bonding is present in a concentration of 3 atomic % or more in the surface side of an oxide film and also is present in a concentration of 0.1 atomic % or less in the interface side of the oxide film can achieve the prevention of the B diffusion and also the prevention of the deterioration of the NBTI resistance in combination. When the Ar/N2 radical nitridation is used, it is difficult for the resultant oxide film to satisfy the condition wherein N in the above bonding state is present in a concentration of 3 atomic % or more in the surface side of an oxide film and simultaneously is present in a concentration of 0.1 atomic % or less in the interface side of the oxide film, whereas, the above distribution of the N concentration can be achieved by using any of the gas combinations of Xe/N2, Kr/N2, Ar/NH3, Xe/NH3, Kr/NH3, Ar/N2/H2, Xe/N2/H2 and Kr/N2/H2.

摘要:
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.

Disclosed is a method for cleaning a semiconductor substrate that can solve a problem of a conventional cleaning method which should include at least five steps for cleaning a substrate such as a semiconductor substrate. The method for cleaning a semiconductor substrate comprises a first step of cleaning a substrate with ultrapure water containing ozone, a second step of cleaning the substrate with ultrapure water containing a surfactant, and a third step of removing an organic compound derived from the surfactant, with a cleaning liquid containing ultrapure water and 2-propanol.

摘要:
For equalizing the rising and falling operating speeds in a CMOS circuit, it is necessary to make the areas of a p-type MOS transistor and an n-type MOS transistor different from each other due to a difference in carrier mobility therebetween. This area unbalance prevents an improvement in integration degree of semiconductor devices. The NMOS transistor and the PMOS transistor each have a three-dimensional structure with a channel region on both the (100) plane and the (110) plane so that the areas of the channel regions and gate insulating films of both transistors are equal to each other. Accordingly, it is possible to make the areas of the gate insulating films and so on equal to each other and also to make the gate capacitances equal to each other. Further, the integration degree on a substrate can be improved twice as much as that in the conventional technique.
