Abstract
A method of forming a semiconductor structure (see e.g., FIG. ) includes forming a silicon (e.g., polysilicon) layer . The silicon layer is patterned and etched so that at least one sidewall is exposed. An oxygen bearing species (e.g., O ) is then implanted into the sidewall of the silicon layer . In the preferred embodiment, the oxygen bearing species is implanted at an acute angle relative to the plane of the silicon layer
