| Filters at source of emissions. Stable resistor-capacitor network. Ideal for high-speed logic. Low lead inductance. Reduces board space compared to discretes. 8-Pin SOIC, PDIP, TSSOP package. Clock termination. Point of contact filtering. Low Pass Filter. EMI/RFI filtering. High speed microprocessor systems like Intel's Pentium, DEC's Alpha, Motorola's 68K and PowerPC , Sun's SPARC, MIPs, and other RISC-based system require well-controlled and precise closk signals to maintain a high performance synchronoussystem. However, very fast edge rated clock signals exhibit transmission line effects on the clock lines resulting in undershoot and overshoot disturbances. CAMD's SWCKT resistor-capacitor integrated thin film networks are specifically designed to eliminate lines. They are effective in suppressing EMI/RFI noise at I/O ports and can also be used as "distributed" AC terminators when filtered lines are dispersed across the board. These networks are fabricated on a silicon substrate using advanced thin film technology. They have low parasitic inductance compared to discrete and conventional thinck film filters and provide effective AC termination and EMI/RFI noise suppression over a wide range of frequencies. The SWCKT is an integrated RC network fabricated on a silicon substrate using advanced thin film technology. This technology insures a fixed time constant and does not create additional skew on the clock lines. It offers very low parasitic inductance compared to conventional discrete thick film-based approaches and provides effective termination at high frequencies. Semiconwell manufactures passive network components, integrated active and passive devices, resistor networks, capacitor networks, schottky and zener diode networks, and npn, pnp transistors arrays that perform the following functions: series and parallel linear and nonlinear GTL, AC, Diode, Thevenin termination networks, precision thin film resistor capacitor networks (RC networks), isolated, bussed resistor networks including zero ohms jumper arrays, voltage divider networks, resistor networks for audio applications, EMI, RFI and ESD zener clamped diodes and transient voltage suppressors networks, EMI/RFI filter networks and clock terminations. Semiconwell's proprietary semiconductor technology, advanced thin films processes, in house assembly and packaging technologies allow manufacturing of flip chip CSP chip scale and MLF molded lead frame surface mount integrated passive networks that include unprecedented large capacitors >1microfarad (1µF) and giga ohms resistors (GW).

| SHORT PRODUCT APPLICATION NOTE |
| High speed microprocessor systems like Intel's Pentium, DEC's Alpha, Motorola's 68K and PowerPC , Sun's SPARC, MIPs, and other TISC-based system require well-controlled and precise closk signals to maintain a high performance synchronous system. However, very fast edge rated clock signals exhibit transmission line effects on the clock lines resulting in undershoot and overshoot disturbances. CAMD's SWCRT 1RC resistor-capacitor integrated thin film networks are specifically designed to eliminate lines. They are effective in suppressing EMI/RFI noise at I/O ports and can also be used as "distributed" AC terminators when filtered lines are dispersed across the board. These networks are fabricated on a silicon substrate using advanced thin film technology. They have low parasitic inductance compared to discrete and conventional thick film filters and provide effective AC termination and EMI/RFI noise suppression over a wide range of frequencies. The SWCKT is an integrated RC network fabricated on a silicon substrate using advanced thin film technology.

| SEMICONDUCTOR-THIN FILM MANUFACTURING PROCESS DESCRIPTION |
| Integrated passive networks are manufactured using advanced thin film technologies including ultra -stable and self passivating Tantalum Nitride resistors, gold interconnect metallization and reliable MNOS capacitors to achieve excellent uniformity, performance and reliability. Thin film resistor technology is the preferred solution for all applications that require low noise, long term stability and excellent performance at very high frequencies. Semiconwell employs proprietary thin film technologies for deposition of a wide range of sheet resistance films from 1 W/sq to 10,000 W/sq. All Semiconwell's products are available in die form and as KGD, known good die and are ideal for high reliability hybrid and multi chip module applications. Besides thin film resistors, Semiconwell integrates capacitors, Schottky diodes, Zener diodes and transistors. Integrated passive and active networks are manufactured using Semiconwell's in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors and Tantalum Nitride resistors are easily integrated with Schottky diodes to provide complete standard and custom RCD solutions. In die form, these products are ideal for hybrid and multi chip module applications. In packaged form, these products are the best solution where space and weight are a concern. |
