  • Soft edge induced local oxidation of silicon
    Patent number: 5920787
    Abstract: A semiconductor device isolating structure and method for forming such a structure. In one embodiment, the semiconductor device isolating structure of the present invention includes a trench formed into a semiconductor substrate. A cross-section of the trench has a first sidewall extending to the bottom surface of the trench, and a second sidewall extending to the bottom surface of the trench. Furthermore, the trench of the present invention also has a first field oxide region formed proximate to the interface of the first sidewall and the top surface of the semiconductor substrate, and a second field oxide region formed proximate to the interface of the second sidewall and the top surface of the semiconductor substrate.
