  • Publication number: 20120094460
    Abstract: A method for fabricating a MOS transistor is disclosed. First, a semiconductor substrate having a gate thereon is provided. A spacer is then formed on the sidewall of the gate, and two recesses are formed adjacent to the spacer and within the semiconductor substrate. Next, the spacer is thinned, and epitaxial layer is grown in each of the two recesses. By thinning the spacer before the epitaxial layer is formed, the present invention could stop the epitaxial layer to grow against the sidewall of the spacer, thereby preventing problem such as Ion degradation.

  • Publication number: 20100042859
    Abstract: A computer has a plurality of sleeping modes to be switch directly. The power supply assemblies provide a plurality of power supplies to elements in the computer. The storage module is used to store executing data corresponding to each sleeping mode. The power management module is used to set the number of the power supply assemblies which need to be switched on in each sleeping mode. The control module determines the sleeping mode which is switched to according to a received trigger event and sends a first switching signal to the storage module to make the storage module store the executing data and a second switching signal to the power management module to make the power management module set the number of the power supply assemblies and switches the sleeping mode of the computer directly.
