摘要: A method for forming shallow trench isolation is disclosed. The method includes forming a trench in a semiconductor substrate, and then blanket depositing a silicon oxide layer over the semiconductor substrate by a plasma process, thereby substantially refilling the trench. Thereafter, a photoresist layer is formed on the plasma deposited silicon oxide layer, followed by etching back a portion of the photoresist layer. The plasma deposited silicon oxide layer is then isotropically etched, and the photoresist layer is then finally removed.

摘要: A method of making vias in a semiconductor IC device having adequate contact to the surface of the interconnects and without inadequate landing is disclosed. The method has interconnects formed in a metal layer on the substrate of the IC device, and a first dielectric layer is formed covering the surface of the interconnects. An etch-stopping layer is then formed on top of the first dielectric layer, followed by the formation of a second dielectric layer on top of the etch-stopping layer. A photoresist layer then covers the second dielectric layer and reveals the surface regions of the second dielectric layer designated for the formation of the vias. A main etching procedure is then performed to etch into the second dielectric layer down to the surface of the etch-stopping layer, thereby forming the first section of the vias. An over-etching procedure is then implemented to strip off the etch-stopping layer and further etches into the first dielectric layer and the etching is then stopped when the surface of the interconnects are revealed to conclude the formation of the vias.

摘要: A method for depositing dielectric material into gaps between wiring lines in the formation of a semiconductor device includes the formation of a cap layer and the formation of gaps into which high density plasma chemical vapor deposition (HDPCVD) dielectric material is deposited. First and second antireflective coatings may be formed on the wiring line layer, the first and second antireflective coatings being made from different materials. Both antireflective coatings and the wiring line layer are etched through to form wiring lines separated by gaps.
