    • A method for manufacturing a semiconductor device is provided to form bulb shaped trenches asymmetrically through a wet etching process, using etching difference between an ion injection section and the other sections for obtaining sufficient ball spacing, which is the distance between the gates. A method for manufacturing a semiconductor device comprises the steps of; forming a device isolation layer(11) in a semiconductor substrate(10); and etching the semiconductor substrate selectively to form bulb shaped trenches(20). The etching process is a wet etching process. The bulb shaped trenches are formed asymmetrically.

    • PURPOSE: A semiconductor device and a manufacturing method are provided to generate a carrier cancellation effect in a domain which is adjacent to each body domain and source and drain by forming a poly silicon film pattern in which impurities of different conductivity type are doped inside a trench. CONSTITUTION: A poly silicon film pattern(109) is formed on a first trench inner wall which defines an active area. An element separation film structure(200) comprises an insulating structure filling up a remaining part of the first trench. The insulating structure comprises a first insulating layer pattern(120b) and a second insulating layer pattern(130) which is successively laminated. A gate structure(170) is formed on the active area of a substrate. A source and drain(180) is formed within the active area which is adjacent to the top of the poly silicon film pattern.
