摘要:
The semiconductor device fabrication method comprises the step of forming gate electrode 20 on a semiconductor substrate 10 with a gate insulation film 18 formed therebetween; the step of implanting dopants in the semiconductor substrate 10 with the gate electrode 20 as the mask to form dopant diffused regions 28, 36; the step of forming a silicon oxide film 38 on the semiconductor substrate 10, covering the gate electrodes 20; anisotropically etching the silicon oxide film 38 to form sidewall spacers 42 including the silicon oxide film 38 on the side walls of the gate electrode 20. In the step of forming a silicon oxide film 38, the silicon oxide film 38 is formed by thermal CVD at a 500-580° C. film forming temperature, using bis (tertiary-butylamino) silane and oxygen as raw materials. Silicon oxide film 38 is formed at a relatively low film forming temperature, whereby the diffusion of the dopant in the dopant diffused regions 28, 36 forming the shallow region of the extension source/drain structure can be suppressed.

Compression stress applying portions 20 of SiGe film are formed in the source/drain regions of the p-MOSA region 30a. Then, impurities are implanted in the p-MOS region 30a and the n-MOS region 30b to form shallow junction regions 22a, 22b and deep junction regions 23a, 23b. The impurity in the shallow junction regions 22a, 22b is prevented from being diffused immediately below the gate insulation film 15 by the thermal processing in forming the SiGe film, the short channel effect is prevented, and the hole mobility of the channel region of the p-MOS transistor 14a. The operation speed of the p-MOS transistor 13a is balanced with that of the n-MOS transistor, whereby the operation speed of the complementary semiconductor device 10 can be increased. The semiconductor device fabricating method can increase and balance the operation speed of a p-transistor with that of an n-transistor.

The invention relates to a flexible scrubbing material that combines at least two discrete components. One component is a continuous flexible substrate. A second component is a discontinuous abrasive layer affixed to the flexible substrate. The abrasive layer is a set of plates formed from a material different than the continuous flexible substrate. One or two flexible substrates with affixed plates can be combined with an intermediate layer such as sponge or terry cloth. The gaps between plates are relatively large and are generally larger than one-third the largest plate dimension. The flexible substrate can be tightly woven fabric that can be printed with visually attractive colors, patterns and images. The plate material is a printable material that subsequently solidifies, such as epoxy. The inventions include associated methods of use and manufacture.

The data transmission rate on the reverse link in a mobile communications system is controlled by determining an interference level at a base station due to signals from all mobile stations served by the base station, and determining a transmission energy level required for each mobile station. The interference level is compared with the transmission energy level to obtain a comparison result for each mobile station, and each mobile adjusts its data transmission rate based upon the comparison result, which is sent via a common channel on a forward link to each mobile station in a dedicated manner. Thereafter, packet data is transmitted on the reverse link in accordance with the adjusting so that data throughput can be maximized.
