Abstract: A polish apparatus for planarizing wafers and films over wafers comprising the following. A substrate chuck for holding a substrate with a surface to be polished thereof being directed about vertically. A first drive means for rotating the substrate chuck. A polishing head having a polishing surface which is adjacent to the substrate during the polishing of the substrate. The polishing surface of the polishing head is smaller than the surface of the substrate. A polishing solution supply means for supplying a polishing solution through the polishing head to the substrate held by the substrate chuck. A reciprocating means for reciprocally moving the polishing head on the surface to be polished. A pressing means for pressing the polishing pad against a substrate held by the substrate chuck by way of the polishing head. The polish head is preferably comprised of one piece of molded polymer. No polish pad is used.

Abstract: A method of manufacturing a shallow trench isolation using a polishing step with reduced dishing. A pad layer, a polish stop layer, a buffer layer and a hard mask layer are formed over a substrate. The hard mask layer has a hard mask opening. We etch a trench opening in the buffer layer, the polish stop layer, the pad layer and form a trench in the substrate using the hard mask layer as an etch mask. We form an oxide trench liner layer along the sidewalls of the trench and an oxide buffer liner layer on the sidewalls of the buffer layer using a thermal oxidation. The hard mask layer prevents the oxidation of the top surface of the buffer layer during the oxidation of the oxide trench liner. This prevents the buffer layer from being consumed by the oxidation and leaves the buffer layer to act in the subsequent chemical-mechanical polish (CMP) step. Next, an insulating layer is formed at least partially filling the trench.

Abstract: A method and apparatus for shallow trench isolation. First, a layer of silicon nitride (SiN) is deposited over a semiconductor substrate. A layer of polysilicon is then deposited over the silicon nitride layer. A layer of tetraethylorthosilicate (TEOS) is deposited over the polysilicon layer. Mask and etch steps are performed to form an opening that extends through the TEOS layer and through the polysilicon layer. An etch step is then performed to etch the exposed side surfaces of the polysilicon layer. Thereby, the exposed side surfaces of the polysilicon layer are moved laterally. An etch step is then performed so as to form a trench that extends into the semiconductor substrate. Dielectric material is deposited such that the dielectric material fills the trench and fills the opening that extends through the polysilicon layer and the silicon nitride layer. The substrate is then polished using a chemical mechanical polishing process.

Abstract: A method of manufacturing a metallization scheme with an air gap formed by vaporizing a filler polymer material. The filler material is covered by a critical permeable dielectric layer. The method begins by forming spaced conductive lines over a semiconductor structure. The spaced conductive lines have top surfaces. A filler material is formed over the spaced conductive lines and the semiconductor structure. The filler material is preferably comprised of a material selected from the group consisting of polypropylene glycol (PPG), polybutadine (PB) polyethylene glycol (PEG), fluorinated amorphous carbon and polycaprolactone diol (PCL) and is formed by a spin on process or a CVD process. We etch back the filler material to expose the top surfaces of the spaced conductive lines. Next, the semiconductor structure is loaded into a HDPCVD chamber. In a critical step, a permeable dielectric layer is formed over the filler material.
