Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent the destruction or deterioration of a gate insulating film by the concentration of an electric field and to manufacture the UMOS semiconductor device of high breakdown voltage by making the depth of a trench to be shallower then a second conductive base area. SOLUTION: In a SiC vertical MOSFET element, the depth of a trench 24 is formed to be shallower than a p-base area 22. When positive voltage is applied to a gate electrode layer 26, an accumulation layer is generated an n-side wall area 20b, a part between a drain electrode 28 and a source electrode 27 is conducted, current is made to flow and it is interrupted when the voltage of the gate electrode 26 is removed. In trench MOSFET, the pn-junction exists in the p-base area 22 in a part deeper than the trench 24. A part where an electric field is concentrated becomes a pn-junction part. Thus, the electric field is prevented from being concentrated on the corner part of the trench 24, tress to a gate insulating film 25 is less and high breakdown voltage becomes possible.

Title: Ship bottom configuration
Inventor: WATANABE SHIGEO
IPC: B63B1/04
Filed: 1985-11-08
Abstract: PURPOSE:To enhance the propelling performance by making the ship with such a longitudinal section that the whole length or part of the bottom consists of a straight or curved line which has a specific upward inclination angle as approaching the stern, and thereby suppressing increase of the shape resistance owing to stern trim. CONSTITUTION:The bottom 5 between AP and FP is given an inclination angle theta3 which is below 5 deg., and the inclination angle generated by trim is represented by theta2, and theta2=theta3 signifies level bottom of ship. Making the bottom shape with approx. theta2=theta3 to the whole length or part of the ship in its longitudinal section will eliminate or minimize dangling of the bottom part or the portion having a cross-area greater than the central part, even though trim is made toward the stern. This reduces defoliation of water stream to be otherwise generated in this part, and this effect will decrease the shape resistance greatly.
