Abstract: PURPOSE: An ADSL(Asymmetric Digital Subscriber Line) using a Q switch is provided to automatically achieve signal conversion between a configuration block using a power of 3 volts and a configuration block using a power of 5 volts in an ADSL interface unit, without the necessity of any additional conversion logic for power control. CONSTITUTION: A cell interface unit(31) receives down ATM cell data outputted from a network interface unit(21) through a cell bus and outputs the input up ATM cell data to the network interface unit(21) through the cell bus. An ATM cell MUX/DEMUX(32) demultiplexes the down ATM cell data received through the cell interface unit(31) and multiplexes the input up ATM cell data. A cell delineation unit(33) receives the down ATM cell data demultiplexed in the ATM cell MUX/DEMUX(32) and disassembles the input ADSL frame into up ATM cell data. A framer/interface unit(34) configures the down ATM cell data received at the cell delineation unit(33) into an ADSL frame and executes interfacing with an external system. A DMT(Discrete Multi Tone) processor(35) executes DMT modulation for the ADSL frame configured in the framer/interface unit(34) and DMT demodulation for an input digital ADSL signal. An analog front end(36) converts the DMT modulated digital ADSL signal into an analog signal and converts an inputted analog ADSL into a digital ADSL signal. A line driver/receiver(37) converts 4 wires for the analog ADSL signal converted at the analog front end(36) into 2 wires and converts 2 wires for an inputted analog ADSL signal into 4 wires. A hybrid transformer(38) executes impedance matching for the analog ADSL signal outputted through the line driver/receiver(37) and outputs it to a splitter(12). The hybrid transformer(38) receives an analog ADSL signal inputted through the splitter(12) after impedance matching. A CPU(39) controls the operation of the cell interface unit(31), the ATM cell MUX/DEMUX(32) and the cell delineation unit(33). An A/D chipset interface/DSP(40) executes an exchange function for control information, status information and initialization to the CPU(39) and an MP(Message Protocol). A Q switch(41) converts control signals, clock signals, reset signals and 16-bit TDMA data necessary between the CPU(39), the framer/interface unit(34), the DMT processor(35), the analog front end(36) and the A/D chipset interface/DSP(40), without the necessity of controlling power additionally.

Abstract: PURPOSE: A device and method for adjusting convergence by spline interpolation are provided so that convergence of a wanted period can be easily selectively adjusted by calculating values between convergence adjusting points and adjusting convergence in a horizontal line or vertical line. CONSTITUTION: A CPU(100) calculates coefficients of a third spline interpolation multinomial in all periods divided by convergence adjusting points composing a plurality of horizontal and vertical lines in order to interpolate values between the convergence adjusting points, and stores the resultant coefficients in a RAM(110). A position coordinate generator(120) outputs a number of the horizontal lines by counting horizontal synchronous signals, and also outputs square and cube root values of the horizontal line number. The position coordinate generator(120) is reset according to a vertical synchronous signal. An adder(160) adds the input values from the RAM(110) and multipliers(130¯150). Accordingly, the adder(160) outputs interpolation data for the values between the adjusting points by the third spline interpolation multinomial. Therefore, current applied to a deviation coil of RGB cathode ray tube is controlled according to the interpolation data, thereby adjusting RGB convergence. As a result, convergence of a wanted period can be easily selectively adjusted, by calculating the values between the adjusting points by using the spline interpolation.

Abstract: PURPOSE: A method for forming a metal interconnect is provided to increase an alignment margin around a contact and to reduce a contact resistance by increasing a bottom area of the metal interconnect by forming the metal interconnect having a sloped profile. CONSTITUTION: After depositing an interlayer insulation film(21) on a silicon substrate(20), barrier metal layers are formed on the interlayer insulation film by a sputtering method. And, a metal layer is deposited on the barrier metal layer by a sputtering method. Then, an ARC(Anti-Reflection Coating) metal layer is formed on the metal layer with a TiN layer. And, a photo resist pattern is formed on the ARC metal layer. Then, a top barrier layer is removed by a dry etching to reveal the surface of the metal layer, and a part of the revealed aluminum metal layer is removed using the photo resist pattern and the remaining ARC metal layer as an etch mask. Therefore, the metal layer has a vertical side profile by forming a trench by removing the ARC metal layer and a part of the metal layer. A remaining metal layer revealed by the formation of the trench is etched using a BCl3 and a Cl2 as an etchant and also using the photo resist pattern and a remaining ARC metal layer(250) as the etch mask. Thus, the remaining metal layer(241) has a sloped etch profile and becomes a pattern of the metal interconnect. The metal barrier layers(230,220) are etched to reveal the surface of the interlayer insulation layer. Therefore, metal interconnect patterns(250,241,230,220) are completed using the remaining aluminum metal layer as a main material.
