PolarFab introduces a SiChrome (SiCr) thin film resistor that features low parasitics and a 500Ω sheet resistance to help reduce die size. The resistor is available on PolarFab's RFBC and ABC3 0.8-micron c-BiCMOS processes, used for manufacturing integrated circuits for high performance amplifier, line driver, consumer electronics, and power management applications. The laser trimmable resistor makes the processes suited for precision analog applications as well. The laser trimmability provides good resistor matching and contributes to a smaller die size and tighter tolerances for repeatable, consistent performance characteristics to reduce the tendency to over-design for process variation. PolarFab's RFBC process can be used to design analog and mixed-signal circuits that operate up to 1.5 GHz and 10 V. The process includes a 9 GHz, 6 V BV_ceo high-performance NPN bipolar transistor, suited for high frequency applications; a 3 GHz, 15 V BV_ceo isolated VPNP for high performance amplifier output stages; a monolithically integrated high linearity/density poly-poly capacitor; and a platinum silicide (PtSi) Schottky diode.
