We investigated the electrical characteristics of p-channel double-diffused MOSFETs (p-LDMOSFETs) with an uneven racetrack source (URS) and a conventional racetrack source (CRS) for PDP driver IC applications. The breakdown voltage of the p-LDMOSFET with the URS in offstate was nearly the same as the p-LDMOSFET with the CRS. However, the breakdown voltage of the p-LDMOSFET with the URS in on-state was about 30% higher than that of the p- LDMOSFET with the CRS, while the saturated drain current of the p-LDMOSFET with the URS was only about 4% lower than that of the p-LDMOSFET with the CRS.
