Granted: 2001-07-11
Abstract: A laptop computer includes a video camera mounted to the lid, preferably embedded into the bezel above the display. The camera includes a CMOS imaging array, video data from which is communicated along a dedicated path from the camera to a graphics controller for output to the display, thereby bypassing the system bus. This makes it possible to display full frame, full data rate video with minimum impact on the overall system performance. Panning and zooming are implemented by software that controls the addresses in the pixel array from which data are transferred to the graphics controller's associated display memory.

Title: Flip chip assembly of semiconductor IC chips
Inventor: DEFELICE RICHARD ALDEN
IPC: H01L21/60
Filed: 2000-04-11
Granted: 2001-08-21
Abstract: The specification describes techniques for soldering IC chips, or other components, to interconnection substrates using a patterned epoxy layer to define the solder interconnections. The epoxy layer is photodefined to form openings that expose the bonding sites on the IC chip (or alternatively the interconnect substrate). Solder paste is deposited in the openings. With the IC chip and the interconnect substrate aligned together, the solder paste is heated to reflow the solder and solder bond the IC chip to the substrate. Heating is continued to cure the epoxy, which serves the function of the conventional underfill. The shape of the solder interconnection is defined by the lithographically formed openings, and the interconnections can be made with very fine pitch. The application of the epoxy underfill in this manner assures complete filling of the gap between the IC chip and the interconnection substrate.

Abstract: At the beginning, a substrate on which a first dielectric layer is deposited is provided. An etching stop layer and a second dielectric layer are deposited on the substrate subsequently. The surface of the second dielectric layer is treated with a Lewis acid. A first photoresist layer is formed on the acid-treated surface of the second dielectric layer and then the first photoresist layer is patterned to form an area for forming a deep pattern. Using the first photoresist layer as a mask, a dry etching process for forming the deep pattern is performed, and the second dielectric layer, the stop layer and the first dielectric layer are etched through subsequently to form a via. The first photoresist layer is removed. Thereafter, the via and the second dielectric layer are treated with the Lewis acid. A second photoresist layer is formed on the second dielectric layer. The second photoresist layer is etched to expose a portion surface of the via and the second dielectric layer for forming a shallow pattern area and the dimension of the shallow pattern in the horizontal direction is larger than that in the vertical direction. Using the second photoresist layer as a mask, a dry etching process for forming the shallow pattern is performed and the etching stop layer is used as an etching stop to remove the exposed surface of the second dielectric layer to a trench with a larger dimension in the horizontal direction. Thereafter, the second photoresist layer is removed to form a metal damascene opening.

Title: Semiconductor device having decision feedback equalizer
Inventor: MORIUCHI TSUNEHIKO
IPC: H04L7/033
Filed: 2000-10-26
Granted: 2003-01-01
Abstract: A read channel for a hard disk includes a decision feedback equalizer (DFE) that is used to demodulate and decode a read signal from a read head or a received signal from a fast communication apparatus by eliminating intersymbol interference from sampled data of the read signal. The DFE has a feed forward equalizer (FFE) that filters the sampled data and generates filtered data. An adder is connected to the FFE and adds the filtered data with a feedback signal to generate an equalization signal. A decision unit connected to the adder compares the equalization signal with a reference signal and generates a decision signal. A shift register connected to the decision unit receives the decision signal. A feedback filter connected to the shift register and the adder receives the decision signal from the shift register and generates the feedback signal. The phase and frequency of a clock signal and the phase and frequency of the input signal are matched using the equalization signal and the decision signal. A replica signal generator connected to the shift register supplies a replica signal, which corresponds with a predetermined decision result, to the shift register in place of the decision-signal during phase and frequency matching.

Abstract: Needle-less injectors for liquids are known in many different forms which are adapted to different conditions of use. The needle-less injector according to the invention is in the form of a hand-held unit. It includes a locking stressing mechanism, an energy-storing spring (36), a hollow plunger (37) displaceable in a cylinder (38) and a nozzle (39). At its one end the hollow plunger is provided with a valve body (42). The supply container (44) for the liquid is arranged within the housing. When the locking stressing mechanism is stressed by rotation of the two housing portions (31, 32) relative to each other the hollow plunger (37) is drawn out of the cylinder (38); at the same time the amount of liquid required for an injection is conveyed out of the supply container (44) through the plunger into the pump chamber (43). After the locking stressing mechanism is triggered the amount of liquid is expelled from the pump chamber through the nozzle. The needle-less injector can be safely and easily handled even by unskilled persons. It is used for the intracutaneous injection of a medicament-bearing liquid into biological tissue, for the injection of an active substance-bearing liquid into a plant or for the injection of a liquid through a membrane into the space behind the membrane.
