A high-voltage p-LDMOS(HV-pMOS) with field-oxide as gate dielectric and a RESURF drain drift region to undertake high gate-source voltage and drain-source voltage for the scan driver chip of plasma display panels (...A high-voltage p-LDMOS(HV-pMOS) with field-oxide as gate dielectric and a RESURF drain drift region to undertake high gate-source voltage and drain-source voltage for the scan driver chip of plasma display panels (PDP) is purposed based on the epitaxial bipolar-CMOS-DMOS (BCD) process. The key considerations and parameters of the design are discussed:the thickness of gate dielectrics is 1mm and the area of the device is 80μm × 80μm. Only 18 photoetching steps are needed in the developed process,which is compatible with standard CMOS, bipolar, and VDMOS devices. The breakdown voltage of the HV-pMOS in the process control module (PCM) is more than 200V. The results are favorable for 170V PDP scan driver chips,which contribute to the competitive cost efficiency.展开更多
