摘要:
A method for making a dual silicide or germanide semiconductor comprises steps of providing a semiconductor substrate, forming a gate, forming source/drain regions, forming a first silicide, reducing spacers thickness and forming a second silicide. Forming a gate comprises forming an insulating layer over the semiconductor substrate, and forming the gate over the insulating layer. Forming source/drain regions comprises forming lightly doped source/drain regions in the semiconductor substrate adjacent to the insulating layer, forming spacers adjacent to the gate and over part of the lightly doped source/drain regions, and forming heavily doped source/drain regions in the semiconductor substrate. The first silicide is formed on an exposed surface of lightly and heavily doped source/drain regions. The second silicide is formed on an exposed surface of lightly doped source/drain regions. A first germanide and second germanide may replace the first silicide and the second silicide.

A regulator includes a first amplifier, a second amplifier, a current control circuit, a first P-type metal-oxide-semiconductor transistor, a second P-type metal-oxide-semiconductor transistor, and a feedback circuit. The current control circuit includes a controller and at least one switch, and a second terminal of the first P-type metal-oxide-semiconductor transistor is coupled to a second terminal of the second P-type metal-oxide-semiconductor transistor. The regulator utilizes the controller to turn off the at least one switch during operation of the regulator in a light load mode, and the regulator utilizes the controller to turn on the at least one switch in turn when the regulator changes from the light load mode to a heavy load mode. Thus, the regulator can quickly recover a load current in the heavy load mode.

An electronic device with movable foot pad, including a body and a foot pad module, is provided. The body has a bottom surface. The foot pad module includes a first foot pad, at least one second foot pad, and at least one rotating shaft connecting the first and second foot pads. The second foot pad is rotated relative to the first foot pad by the rotating shaft to switch the foot pad module between first and second states. An axial direction of the rotating shaft is inclined relative to the bottom surface. In the first state, the body is supported on the platform by the first and second foot pads. In the second state, the second foot pad is rotated 180 degrees relative to the first foot pad in the axial direction and protrudes from the first foot pad to support the body on the platform by the second foot pad.

A method and an apparatus for multimedia data management are disclosed. The method provides an indexing and retrieval scheme for digital photos with speech annotations based on image-like patterns transformed from the recognized syllable candidates. For annotated spoken content, the recognized n-best syllable candidates are transformed into a sequence of syllable-transformed patterns. Eigen-image analysis is further adopted to extract the significant information to reduce the dimensionality. Vector quantization is applied to quantize the syllable-transformed patterns into feature vectors for indexing. The invention of indexing scheme reduces the dimensionality and noise of data, and achieves better performance of 16.26% for speech annotated photo retrieval.
