    摘要: A trench isolation structure including growing a layer of thermal oxide (114) on the silicon exposed in the trenches (110) prior to depositing the layer of insulating material, wherein the layer of thermal oxide (114) forms a lining on the trench. Depositing the layer of insulating material (120) comprises depositing a silicon oxide with an inductively-coupled high density plasma, wherein the plasma bias of the high density plasma is ramped from a low bias to a high bias
