Title: Method for manufacturing semiconductor device
Inventor: KOTANI NAOKI
IPC: H01L21/762
Filed: 2001-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a SOI device which can restrain electric field concentration by oxidizing and rounding an upper surface edge part of a semiconductor layer. SOLUTION: A mask 4 for active region formation is formed in a part on an Si layer 2 via a thermal oxide film 3. After a dummy side wall 8 is formed on the side surface of the mask 4, etching is performed by using the mask 4 and the side wall 8 as masks, and a trench 9 being in contact with the side surface of the Si layer 2 is formed. The trench 9 is filled with a plasma CVD oxide film 11, which is polished until the side wall 8 is exposed on a surface. Oxidation is performed in the state that an upper surface edge part of the Si layer 2 is exposed by eliminating the side wall 8. As a result, the upper surface edge part of the Si layer 2 can be oxidized without causing oxidation of a lower surface edge part of the Si layer 2.

IPC: H01L21/3065
Filed: 2001-08-29
Abstract: PROBLEM TO BE SOLVED: To provide a field-effect transistor having a high electrostatic breakdown voltage, and a manufacturing method thereof. SOLUTION: In this embodiment, a gradient angle of a mesa step in a field- effect transistor is gently tapered without exceeding 45 deg.. The mesa step is formed by dry-etching using a tapered shape of a resist. After the resist is coated on a semiconductor, a pattern is formed by exposure. Although the resist is formed vertically at this time, it is heat-treated, for example, at 130 to 150 deg.C so that a tapered angle is formed not exceeding 60 deg.. Then, the semiconductor layer part is etched 0.2 μm by dry-etching. Depending on the difference in etching rate of the resist, the mesa step having the height of approximately 0.2 μm and the gradient angle of approximately 35 deg. is formed.
