Patent JP-2002100684-A (JP)
Title: Semiconductor device
Inventor: NEGORO TAKAAKI
IPC: H01L27/092
Filed: 2000-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device where a high-voltage CMOS and a low-voltage CMOS are mounted on the same semiconductor substrate while malfunction caused by a parasitic bipolar transistor is prevented. SOLUTION: A low-voltage CMOS region 3 comprising a PchMOS7 and an NchMOS9 as well as a high-voltage CMOS region 5 comprising an NchLDMOS11 and a PchLDMOS13 are formed on a P-type substrate 1. Since the NchMOS9 is formed in an N-type well region 17, a substrate current does not flow to the P-type substrate 1 when the NchMOS9 is operated, thus a parasitic bipolar transistor comprising the N-type well region 17, the P-type substrate 1, and an N-type well region 21 is not operated. The PchLDMOS13 is formed in an N-type well region 25. Since the N-type well region 25 is applied with the highest electric potential within the device, the parasitic bipolar transistor comprising the P-type substrate 1, the N-type well region 25, and a P-type well region 27 is not operated.
