    Abstract: A structure for and method of forming a trench in a semiconductor body is disclosed herein. A field oxide 16 is grown over a portion of n-well 8 where trench 26 is to be formed. Nitride layer 20 and TEOS oxide layer 22 are deposited. Resist 24 is patterned and TEOS layer 22, nitride layer 20, and field oxide layer 16 are etched. Resist 24 is removed and trench 26 is etched through n-well 8 and into substrate 4. Thin oxide 28 is then grown on the sidewalls of trench 26. Polysilicon is deposited into trench 26 and etched back to form polysilicon plug 30. Sidewall oxide 32, to prevent voids in the topography of trench 26, is formed on top of polysilicon plug 30 along the outer edges of trench 26. To prevent leakage into trench 26, a thick thermal oxide cap 34 is grown over trench 26.

    Abstract: A method of photolithographically forming an integrated circuit feature, such as a conductive structure, for example a gate electrode (15), or such as a patterned insulator feature, is disclosed. A critical dimension (CD) for a photolithography process defines a minimum line width of photoresist or other masking material that may be patterned by the process. A photomask (20, 30, 40, 50, 60) has a mask feature (25, 35, 45, 55, 65) that has varying width portions along its length. The wider portions have a width (L1) that is at or above the critical dimension of the process, while the narrower portions have a width (L2) that is below the critical dimension of the process. In the case of a patterned etch of a conductor, photoexposure and etching of conductive material using the photomask (20, 30, 40, 50, 60) defines a gate electrode (15) for a transistor (10) that has a higher drive current than a transistor having a uniform gate width at the critical dimension.
