Abstract
Reduced surface field lateral double-diffused MOS transistor for the driving circuits of plasma display panel and field emission display in the 120V region have been integrated for the first time into a low-voltage $1.2{\mu}m$ analog CMOS process using p-type bulk silicon. This method of integration provides an excellent way of achieving both high power and low voltage functions on the same chip; it reduces the number of mask layers double-diffused MOS transistor with a drift length of $6.0{\mu}m$ and a breakdown voltage greater than 150V was self-isolated to the low voltage CMOS ICs. The measured specific on-resistance of the lateral double-diffused MOS in $4.8m{\Omega}{\cdot}cm^2$ at a gate voltage of 5V.
