    摘要: One aspect provides a method of manufacturing a semiconductor device having reduced N/P or P/N junction crystal disorder. In one aspect, this improvement is achieved by forming gate electrodes over a semiconductor substrate, amorphizing the semiconductor substrate that creates amorphous regions adjacent the gate electrodes to a depth in the semiconductor substrate. Source/drains are formed adjacent the gate electrodes by placing conductive dopants in the semiconductor substrate, wherein displaced substrate atoms and the conductive dopants are contained within the depth of the amorphous regions. The semiconductor substrate is annealed to re-crystallize the amorphous regions subsequent to forming the source/drains.

    摘要: A method for reducing curvature of a wafer having a semiconductor surface. One or more process steps are identified at which wafers exhibit the largest curvature, and/or wafer curvature that may reduce die yield. A crystal damaging process converts at least a portion of the semiconductor surface into at least one amorphous surface region After or contemporaneously with the crystal damaging, the amorphous surface region is recrystallized by recrystallization annealing that anneals the wafer for a time ≦5 seconds at a temperature sufficient for recrystallization of the amorphous surface region. A subsequent photolithography step is facilitated due to the reduction in average wafer curvature provided by the recrystallization.

    摘要: The present invention provides, in one embodiment, a process for fabricating a metal oxide semiconductor (MOS) device (100). The process includes forming a gate (120) on a substrate (105) and forming a source/drain extension (160) in the substrate (105). Forming the source/drain extension (160) comprises an abnormal-angled dopant implantation (135) and a dopant implantation (145). The abnormal-angled dopant implantation (135) uses a first acceleration energy and tilt angle of greater than about zero degrees. The dopant implantation (145) uses a second acceleration energy that is higher than the first acceleration energy. The process also includes performing an ultrahigh high temperature anneal of the substrate (105), wherein a portion (170) of the source/drain extension (160) is under the gate (120).

    摘要: The disclosure relates to a method of forming an n-type doped active area on a semiconductor substrate that presents an improved placement profile. The method comprises the placement of arsenic in the presence of a carbon-containing arsenic diffusion suppressant in order to reduce the diffusion of the arsenic out of the target area during heat-induced annealing. The method may additionally include the placement of an amorphizer, such as germanium, in the target area in order to reduce channeling of the arsenic ions through the crystalline lattice. The method may also include the use of arsenic in addition to another n-type dopant, e.g. phosphorus, in order to offset some of the disadvantages of a pure arsenic dopant. The disclosure also relates to a semiconductor component, e.g. an NMOS transistor, formed in accordance with the described methods.
