摘要:
A method and structure are provided with reduced gate wrap around to advantageously control for threshold voltage and increase stability in semiconductor devices. A spacer is provided aligned to field dielectric layers to protect the dielectric layers during subsequent etch processes. The spacer is then removed prior to subsequently forming a part of a gate oxide layer and a gate conductor layer. Advantageously, the spacer protects the corner area o the field dielectric and also allows for enhanced thickness of the gate oxide near the corners.

摘要:
Substrate isolation trench (224) are formed in a semiconductor substrate (120). Dopant (e.g. boron) is implanted into the trench sidewalls by ion implantation to suppress the current leakage along the sidewalls. During the ion implantation, the transistor gate dielectric (520) faces the ion stream, but damage to the gate dielectric is annealed in subsequent thermal steps. In some embodiments, the dopant implantation is an angled implant. The implant is performed from the opposite sides of the wafer, and thus from the opposite sides of each active area. Each active area includes a region implanted from one side and a region implanted from the opposite side. The two regions overlap to facilitate threshold voltage adjustment.
