Inventor: LEE NAM YEONG
IPC: H01L27/092
Filed: 2001-06-28
Abstract: PURPOSE: A fabrication method of semiconductor devices is provided to prevent a latch-up by using a P-well having a deep depth compared to an N-well. CONSTITUTION: A trench(206) is formed by selectively etching a P-type silicon substrate(200) using a buffer layer. A P-well(214) is formed in the substrate(200) by implanting dopants using the first photoresist pattern for exposing a P-well formation region. After removing the first photoresist pattern, an isolation layer(211) is filled into the trench(206). An N-well(212) is then formed in the substrate(200) by implanting dopants using the second photoresist pattern(222) for exposing an N-well formation region. At this time, the N-well(212) has a relatively shallow depth compared to the junction region with the P-well(214) by controlling a dose or an energy intensity.
