Abstract: A new method of forming shallow trench isolations without using CMP is described. A plurality of isolation trenches are etched through an etch stop layer into the semiconductor substrate leaving narrow and wide active areas between the trenches. An oxide layer is deposited over the etch stop layer and within the trenches using a high density plasma chemical vapor deposition process (HDP-CVD) having a deposition component and a sputtering component wherein after the oxide layer fills the trenches, the deposition component is discontinued while continuing the sputtering component until the oxide layer is at a desired depth. In one method, the oxide layer overlying the etch stop layer in the wide active areas is etched away. The etch stop layer and oxide layer residues are removed to complete planarized STI regions.

Abstract: An apparatus and method are disclosed for purifying a contaminated fluid stream, for example an air stream contaminated with volatile organic compounds. A sorption media is directed between narrowly spaced plates which control the depth of sorbant flow. In an adsorber the plates are porous to allow the contaminated air to pass into an adsorption chamber where the media removes the contaminates from the fluid stream. In a desorber the plates may be transmissive or reflective of microwave energy and porous to a purging gas in a desorption chamber where the media releases the contaminates to refresh the media. An inclined plane or conical surface is contemplated for a desorber which can be coupled to an adsorber in a closed loop system.
