    摘要: A semiconductor process in which oxygen is selectively implanted into isolation regions of a semiconductor substrate and subsequently annealed to form isolation structures within the isolation regions. Preferably, a semiconductor substrate is provided and a pad oxide layer is deposited on the semiconductor substrate. A barrier layer is then deposited on the pad oxide layer and a photoresist layer is formed over the barrier layer and patterned to form a photoresist mask. The photoresist mask is aligned over active regions of the semiconductor substrate. An oxygen bearing species is then introduced to an isolation region of the semiconductor substrate. The isolation region is laterally displaced between the active regions. The introducing of the oxygen bearing species into the isolation region results in the formation of an oxygenated region of the semiconductor substrate. Thereafter, the semiconductor substrate is annealed to react the oxygen bearing species with the semiconductor substrate atoms within the isolation region thereby forming an isolation oxide within the isolation region. The introduction of the oxygen bearing species into the semiconductor substrate preferably is accomplished by implanting oxygen ions into the substrate. In one embodiment the annealing of the semiconductor substrate is accomplished by immersing the semiconductor substrate in an ambient maintained at a temperature in the range of approximately 600.degree. C. to 900.degree. C. for a duration in the range of approximately 2 to 20 minutes. In another embodiment, the annealing the semiconductor substrate is accomplished during subsequent fabrication processing such that the annealing requires no dedicated processing step.

    摘要: A semiconductor device having a gate electrode stack formed using a patterned oxide layer is disclosed. The device is formed by forming an oxide layer over a surface of a substrate and forming at least one opening in the oxide layer. A high permittivity plug (e.g., a BST plug) is formed in the lower portion of the opening. A conductive plug (e.g., a metal silicide plug) is formed in an upper portion of the opening over the high permittivity plug. Remaining portions of the oxide layer are then removed. The conductive plug and high permittivity plug may form a gate electrode and a gate insulating layer, respectively.

    摘要: A method of making a semiconductor device includes forming gate electrode over a substrate and a protective layer over the gate electrode. A portion of the protective layer is selectively removed to expose a peripheral region of the gate electrode. A remainder of the protective layer remains disposed over a central region of the gate electrode. An upper portion of the peripheral region of the gate electrode is then removed typically leaving an underlying portion. Often, a dopant material is implanted into the substrate adjacent to and beneath the underlying portion to simultaneously form lightly-doped and heavily-doped regions beneath and adjacent to the underlying portion, respectively. In addition, all or part of the underlying portion may be oxidized to provide a gate electrode with reduced width.

    摘要: A transistor and a method for making a transistor are described. Barrier species such as nitrogen may be introduced into a semiconductor substrate to form a barrier layer. A dielectric having a high dielectric constant, preferably a metal- and oxygen-bearing dielectric, may then be deposited upon the semiconductor substrate. The barrier layer preferably mitigates short channel effects and prevents dopant and/or metal atom migration into or out of the gate structure. The dielectric may be annealed in an oxygen-bearing atmosphere to passivate the dielectric material and to incorporate barrier species into the dielectric. Alternatively, the anneal may be performed in an inert atmosphere. Following deposition of a conductive gate material upon the dielectric, a gate conductor and gate dielectric may be patterned. Lightly doped drain impurity areas and/or source and drain impurity areas may then be formed in the semiconductor substrate.
