Abstract:
An electrical connector includes an insulative housing, a plurality of first and second contacts retained in the insulative housing and a metallic ground. Each first contact comprises a first contact portion and a first mounting portion. Each second contact comprises a second contact portion and a second mounting portion. The first and second mounting portions are respectively arranged in first and second rows. The second contacts comprise a grounding contact. The ground piece comprises an elastic contact beam for abutting against the grounding contact so that the surface of the grounding contact is expanded. As a result, cross-talk occurred between the contacts can be decreased.

Abstract:
Over-voltage indicator and related circuit and method. The over-voltage indicator can work with an I/O circuit of a chip for detecting over-voltage in an I/O pad and providing an indication signal accordingly. When over-voltage does not happen, the over-voltage indicator continues to detect a signal level of the I/O pad and keeps the indication signal low. Once over-voltage is detected, the over-voltage indicator pauses detecting, asserts a high level in the indication signal, and periodically resumes detecting until end of over-voltage is detected. With informing provided by the indication signal, a core cell of the chip can perform proper operation to reduce potential damage caused by over-voltage.

A composite semiconductor structure and method of forming the same are provided. The composite semiconductor structure includes a first silicon-containing compound layer comprising an element selected from the group consisting essentially of germanium and carbon; a silicon layer on the first silicon-containing compound layer, wherein the silicon layer comprises substantially pure silicon; and a second silicon-containing compound layer comprising the element on the silicon layer. The first and the second silicon-containing compound layers have substantially lower silicon concentrations than the silicon layer. The composite semiconductor structure may be formed as source/drain regions of metal-oxide-semiconductor (MOS) devices.

Abstract:
A process of automatically translating an extended activity diagram (EAD) into a hardware component graph (HCG). For translating the high level programming language into a Very High Speed Integrated Circuit Hardware Description Language (VHDL), the high level programming language is first translated into an activity diagram (AD), then the AD is translated into an HCG, which can indicate a connection relation between hardware components, and finally corresponding HDL codes are generated according to the HCG
