Title: Method for manufacturing shallow trench isolation area
Inventor: SHR SHIUE-HAU
IPC: H01L21/76
Filed: 1998-12-23
Granted: 2000-05-21
Abstract: A method for manufacturing shallow trench isolation area is disclosed. The method first forms a pad oxide layer and a mask layer on the substrate to define a trench in the substrate. Then, a process for growing liner oxide layer is carried out by wet thermal oxidation method in a temperature of 950 to 1180 degree C. With such a condition, the silicon substrate exposed via the trench can be oxidized and the surface of the mask layer is also oxidized. Therefore, the produced liner oxide layer not only covers the surface of the trench but also extends to cover the surface of the mask layer. Next, the trench is filled with filling material which is then planarized. Finally, the mask layer and the pad oxide layer are removed.

Granted: 2000-10-11
Abstract: A method and apparatus for depositing a low dielectric constant film by reaction of an organosilicon compound and an oxidizing gas at a constant RF power level from about 10W to about 200W or a pulsed RF power level from about 20W to about 500W. Dissociation of the oxidizing gas can be increased prior to mixing with the organosilicon compound, preferably within a separate microwave chamber, to assist in controlling the carbon content of the deposited film.

The oxidized organosilane or organosiloxane film may also be used as an etch stop and an intermetal dielectric layer for fabricating dual damascene structures. The oxidized organosilane or organosiloxane films also provide excellent adhesion between different dielectric layers. A preferred oxidized organosilane film is produced by reaction of methylsilane, CH3SiH3, dimethylsilane, (CH3)2SiH2, or 1, 1, 3, 3-tetramethyl-disiloxane, (CH3)2-SiH-O-SiH-(CH3)2, and nitrous oxide, N2O, at a constant RF power level from about 10W to about 150W, or a pulsed RF power level from about 20W to about 250W during 10% to 30% of the duty cycle.

Granted: 2000-10-11
Abstract: A dual band RF architecture including a GSM quadrature modulator for modulating an intermediate frequency (IF) wherein the frequency of the modulated IF signal is changed such that one IF is used for the GSM band and another IF is used for the DCS 1800 band. An intermediate frequency (IF) filter with a pass band that covers both the GSM IF and the DCS 1800 IF is connected to the output of the modulator and outputs to a transmit phase lock loop, which translates the IF signal from the IF filter to either a DCS 1800 band radio frequency signal or a GSM band radio frequency signal, depending on the frequency of a local oscillator (LO). The receiver employs a down converter which provides a down converted output signal selected by high side injection for the GSM band an by low side injection for the DCS 1800 band. The down converter outputs to an intermediate frequency (IF) receiver filter centered at 400 MHz designed to pass either the down converted GSM signal or the down converted DCS signal to demodulation circuitry. A single phase lock loop circuit is used to supply, on a signal output, the LO signal for down converting either the GSM receive band or the DCS 1800 receive band, as well as the LO for the transmit phase lock loop.

Abstract: A data-processing arrangement (DPA) comprises a plurality of data processors (P) for carrying out operations (0) in parallel. An operation (0) carried out by a processor (P) is defined by an instruction word (IW) supplied to the data processor (P). The data-processing arrangement (DPA) comprises a control processor (CP) for making compositions of instruction words (VLIW) on the basis of instruction-word composing software (IWCS). A composition of instruction words (VLIW) defines operations (0) which are carried out in parallel. Storage of instruction-word composing software will generally require less memory space than storage of VLIWs as such. The cost saving this provides will generally outweigh the additional costs associated with a control processor for making compositions of instruction words. Thus, the data-processing arrangement described hereinbefore yields a better cost efficiency.

Title: Shift register architecture of selective multiple shifts
Inventor: CHEN SHING-YI
IPC: H03K23/00
Filed: 2000-09-25
Granted: 2002-10-21
Abstract: The present invention relates to a shift register architecture of selective multiple shifts for generating addresses pointing to a unit cell matrix. Each one of the N rows of the unit cell matrix has a word line and each word line has a corresponding value. In accordance with the address value of an address signal, the corresponding word line can be activated so that data read/write can be carried out towards the unit cells on the word line. The shift register consists of a control circuit and a multi-shift circuit. The control circuit is used for outputting a clock signal and i shift signals (where 0 < i < N and i is an integer). If one of the shift signals is at high level, the other shift signals must be at low level. The multi-shift circuit includes N sets of register units connected in series and each register unit consists of a flip-flop and a multiplexer. Each flip-flop can output a unique address and each multiplexer can receive all the signals outputted from the control circuit. Also, the jth multiplexer can receive the output addresses of the jth to the (j-i+1) th flip-flops. Each shift signal corresponds to one of the received addresses. In accordance with the high-level shift signal in the received shift signals, each multiplexer selects an address corresponding to the high-level shift signal from the received addresses before outputting the selected address to the flip-flop of the register unit on the next level. Thus, the address pointing time can be shortened effectively.
