Title: Semiconductor device
Inventor: TSUCHIYA TAKAFUMI
IPC: H01L21/337
Filed: 2002-08-29
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem in which a conventional semiconductor device deteriorates in operation efficiency for chip area since, when the number of guard rings is increased, the formation area of guard rings 7 in a chip increases and then an element formation region in the chip is reduced.  <P>SOLUTION: For obtaining a desired dielectric strength characteristic, a semiconductor device has a 1st guard ring 36 and a 2nd guard ring 37 differing in depth. The 1st guard ring 36 and a gate region 29 are made nearly equal in diffusion depth. The 2nd guard ring 37 is formed through a 2nd trench 35. Consequently, a depletion layer line 34 can be formed having a gentle slope to a pn junction formed of a drain region 23 and the guard rings 36 and 37, etc., without large variation in curvature. Consequently, effective use of chip area and maintenance of the dielectric strength characteristic can be realized.  <P>COPYRIGHT: (C)2004,JPO
