is then refilled with an insulating material. The resulting structure is referred to as a shallow trench isolation (STI) structure. The active region typically comprises source/drain regions formed in the semiconductor substrate by implantation of impurities, spaced apart by a channel region on which a gate electrode is formed with a gate oxide layer therebetween. The gate electrode controls the turn-on and turn-off of each transistor.
A typical method of trench formation comprises initially growing a pad oxide layer on the substrate, and depositing a nitride polish stop layer thereon. A photoresist mask is then applied to define the trench areas. The exposed portions of the nitride layer are then etched away, followed by the pad oxide layer. The etching continues into the substrate to form the shallow trench.color with aromas of lemongrass, passionfruit and freshly mown grass. The palate is vibrant and fresh, reflecting the combination of low alcohol, crisp acid and deliate body that make this wine so refreshing to sip, especially when paired with freshly caught King George Whiting, simply grilled and served with lemon wedges.
