M31 BCD (Bipolar/CMOS/DMOS) Process Foundation IP Solutions


Power Management IC (PMIC) is emerging in semiconductor market, with origins linked to the growing environmental protection trend. PMIC plays a key role in this field due to the ability to improve power efficiency for electronic devices better than conventional discrete solutions. The technology trends of BCD (Bipolar-CMOS-DMOS) technology are in terms of voltage capability, switching speed of power transistor, and high integration of logic CMOS for SoC (System-on-Chip) solution requiring high-voltage devices.

BCD technology offers low voltage logic CMOS transistors, high-voltage CMOS transistors, bipolar transistors, resistors, capacitors, diodes, and power LDMOS (lateral double-diffused MOS) transistors in the same process. The compatibility between BCD and CMOS process is crucial for IP reuse which will save customers much time and resources. Normally BCD process has the parasitic bipolar transistors which can design analog circuits like banggap reference. A LDMOS is used as a main power switch so that the on-resistance is very important to reduce the power dissipation and the size of the die.
