摘要:
A method of forming a generally T-shaped structure. The method comprises forming a poly/amorphous silicon layer stack which comprises a polysilicon layer and a generally amorphous silicon layer overlying the polysilicon layer. The method further comprises selectively etching the poly/amorphous silicon layer stack, wherein an etch rate associated with the generally amorphous silicon layer in an over etch step associated therewith is less than an etch rate associated with the polysilicon layer, thereby causing a lateral portion of the generally amorphous silicon layer to extend beyond a corresponding lateral portion of the polysilicon layer.

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.
