摘要:
A trench isolation structure including high density plasma enhanced silicon dioxide trench filling (122) with chemical mechanical polishing removal of non-trench oxide.
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

摘要:
A two-stage plasma enhance dielectric deposition with a first stage of low capacitively-coupled RF bias with conformal deposition (202) followed by high capacitively-coupled RF bias for planarizing deposition (204) limits the charge build up on the underlying structure (104, 106, 108).
