摘要： A method for forming metal silicide regions in source and drain regions (160, 170) is described. Prior to the thermal annealing of the source and drain regions (160, 170), germanium is implanted into a semiconductor substrate adjacent to sidewall structures (90, 95) formed adjacent gate structures (60, 70). The position of the implanted germanium species in the semiconductor substrate will overlap the source and drain regions (160, 170). Following thermal annealing of the source and drain regions (160, 170), the implanted germanium prevents the formation of metal silicide spikes.

摘要： An improved metallized structure (10) is formed from a copper seed layer (46) and a copper structure (48). Semiconductor devices to be connected (16-18) are covered by a conductive barrier layer (20). An oxide layer (28) is then deposited over the barrier layer (20) and patterned using standard photolithographic techniques and an anisotropic plasma etch. Vertical sidewalls (36-38) are formed by the etch and an HF deglaze. A seed layer (44-46) is then sputtered onto a photoresist layer (30) and the exposed barrier layer (20). After stripping the photoresist (30) and the seed layer (44) thereon, the copper structure (48) is electroplated over the remaining seed layer (46). The structure (48) thus formed has approximately vertical sidewalls (24-26) for improved contact with subsequent layers.

摘要： A thin film etching process, wherein the rate of deposition of a robust sidewall passivant is controlled so that passivants can be continually deposited on the sidewalls of the resist pattern to change the geometry of the resist pattern during the processing step. That is, the existing pattern is modified as if a sidewall filament has been deposited on it, which can be advantageous for many purposes, without the added process complexity required by a sidewall filament process.

摘要： A fluorine based metal etch chemistry, wherein an admixture of etch products (or species which are closely related to etch products) is added during the post etch stage, i.e. during the stage when the pattern has partially cleared by overetch is not yet completed, to maintain the balance of chemistries which provides selectivity and anisotropy. In a tungsten etch, WF.sub.6 is usefully added during the post etch period to provide this loading.
