Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To reduce the on-resistance of a high-withstand voltage semiconductor device while the high withstand voltage of the device is maintained by constructing a reduced surface field structure by providing an epitaxial layer having a second conductivity on a buried layer having a first conductivity. SOLUTION: In a horizontal MOSFET, a low-resistance n-type buried layer 2 is formed on a p-type semiconductor substrate 1 and a high-resistance epitaxial layer 3 having a thickness of about 4 μm is formed on the buried layer 2 by epitaxial growth. Then a high-resistance n-type offset layer 4 is selectively formed on the layer 3 and p-type body layers 5 are selectively formed on the layer 3 at locations other than that of the offset layer 5. In addition, low- resistance n-type source layers 6 are selectively formed on the surfaces of the p-type body layers 5. By constructing a reduced surface field structure by providing a p-type epitaxial layer 3 on the n-type buried layer 2, the on-resistance of the MOSFET can be increased by relieving the local concentration of electric fields by eliminating the lower corners of the body layers 5.  Therefore, the MOSFET can be maintained at a high withstand voltage.

Filed: 1990-07-16
Abstract: PURPOSE:To surely calculate the capacity value of a mask pattern by converting continuous apex coordinates of the mask pattern into segments to calculate its peripheral length and calculating the area by segments and calculating the capacity value by the peripheral length and the area.
