An bonding pad structure has a passivation layer over a copper layer having a pad window to expose a portion of the copper layer, a barrier layer conformal to a profile of the pad window, and an aluminum pad located in the pad window. The metal layer can be an aluminum, aluminum alloy or aluminum dominated layer for providing a better adhesion property between the copper layer and the bonding wire.

An overdrive system for driving a display device. A host machine includes a display interface for connecting with the display device. The display interface includes a display chip and a video memory. The overdrive system includes a frame buffer for holding the display data of the previous frame. The frame buffer uses a portion of the video memory space. The overdrive system also includes an overdrive look-up table coupled to the display chip to provide a correspondence between the overdrive disp...

A refrigerant cycling device is provided, wherein a compressor comprises an electric motor element, a first and a second rotary compression elements in a sealed container. The first and the second rotary compression elements are driven by the electric motor element. The refrigerant compressed and discharged by the first rotary compression element is compressed by absorbing into the second rotary compression element, and is discharged to the gas cooler. The refrigerant cycling device comprises an...

An apparatus and a method for supporting multi-processors and a motherboard using the same are provided. The apparatus receives the pins Z36 and AK36 of the Socket-370 central processing unit to determine which type the Socket-370 central processing unit is. According to the suspend status input signal transmitted from the south bridge of the motherboard, the determined result is latched, and some appropriate circuits are coupled to the Socket-370 central processing unit via a switch circuit. Me...

A vertical routing structure inside a substrate for connecting a pair of trace lines electrically. The trace lines are positioned on the top and bottom surface of a stack layer. The vertical routing structure includes a conductive rod and two bonding pads. The conductive rod passes through the stack layer such that the top and bottom surface of the conductive rod are also exposed on the top and bottom surface of the stack layer. In addition, a bonding pad is also attached to the top and bottom s...

A tablet conveying and cutting apparatus capable of adjusting the position of a tablet is a structure suitable for downsizing. A tablet conveying and cutting apparatus has an arranging device for arranging a long side of the tablet to be perpendicular to the tablet's moving direction by moving the tablet for a predetermined distance; and an oblique plate for making the tablet fall a predetermined distance.

Each of the flat surfaces of the pin-seal portions is formed such that the width thereof in the second direction gradually increases as far as the portion upper than the stud pin in the direction from the side of the face portion to the side of the seal end surface, and forms the symmetrical shape about the center portion in the second direction. Namely, the flat surface is formed so as to have the substantially half ellipse shape which has the major axis in the second direction, and protrudes t...

A disc device, in which the recording medium can be inserted/ejected by a way of slot-in type no matter which type or shape the recording medium is. When the operator ejects the disc cartridge after it has been loaded in the disc device, by raising the holder, installed with the disc cartridge, the disc holder of the disc lever, supported by the carrier unit, will be in contact with the tip protrusion of the rotating member and will press upward the tip protrusion of the rotating member. Then, b...

A circuit for calibrating the output driving strength of a DRAM and method thereof is provided. A driving strength auto-compensation circuit is used to adjust the resistance value of an output generator inside a memory control chip and match with the target output driving strength of the DRAM. Hence, the input comparator of the memory control chip can be directly used to read from the DRAM and generate an output value so that extra high gain comparators are not required for accurately calibratin...
