Summary: | An LDMOS device and a method for forming the LDMOS device are provided. The LDMOS device includes: a substrate formed with a source region, a drain region and a drift region; a gate structure; a silicide block layer; a first conductive structure having one end electrically connected with the source region, a second conductive structure having one end electrically connected with the drain region; a first metal interconnecting structure electrically connected with the other end of the first conductive structure, a second metal interconnecting structure electrically connected with the other end of the second conductive structure; a third conductive structure having one end disposed on a surface of the silicide block layer; and a third metal interconnecting structure electrically connected with the other end of the third conductive structure. The LDMOS device has increased breakdown voltage, and reduced on-resistance, and its preparation process is safer and easier to control. |
