    摘要： An object of the present invention is to provide a thermal airflow sensor that prevents moisture absorption by a silicon oxide film formed closest to a surface (formed to be located on an uppermost portion), and that reduces a measuring error. In order to attain the foregoing object, the thermal airflow sensor according to the present invention applies an ion implantation to a silicon oxide film 4, formed closest to a surface (formed to be located on an uppermost portion), by using an atom or molecule selected from at least any one of silicon, oxygen, and an inert element such as argon or nitrogen, in order to increase a concentration of an atom contained in the silicon oxide film 4 more than that before the ion implantation.

    摘要： After a gate electrode is formed on a main surface of a semiconductor substrate, low concentration layers are formed on the main surface of the semiconductor substrate by implanting impurities therein, with using the gate electrode as a mask. Thereafter, first sidewalls and second sidewalls are formed on the both side surfaces of the gate electrode. Subsequently, nitrogen or the like is ion-implanted into the semiconductor substrate, with using the first sidewalls, the second sidewalls and the gate electrode as a mask, thereby forming a crystallization-control region (CCR) on the main surface of the semiconductor substrate. Then, after the second sidewalls are removed, high concentration layers for a source and a drain are formed on the main surface of the semiconductor substrate.

    摘要： A semiconductor integrated circuit device and a method of manufacturing the same. The surface of a substrate of an active region surrounded by an element isolation trench is horizontally flat in the center portion of the active region but falls toward the side wall of the element isolation trench in the shoulder portion of the active region. This inclined surface contains two inclined surfaces having different inclination angles. The first inclined surface near the center portion of the active region is relatively steep and the second inclined surface near the side wall of the element isolation trench is gentler than the first inclined surface. The surface of the substrate in the shoulder portion of the active region is wholly rounded and has no angular portion.
