摘要:
Provided is a method and structure for utilizing advance channel substrate materials in semiconductor manufacturing. Advanced channel substrate materials such as germanium and Group III-V channel substrate materials, are advantageously utilized. One or more capping films including at least a nitride layer are formed over the channel substrate prior to patterning, ion implantation and the subsequent stripping and wet cleaning operations. With the capping layers intact during these operations, attack of the channel substrate material is prevented and the protective films are easily removed subsequently. The films are dimensioned in conjunction with the ion implantation operation to enable the desired dopant profile and concentration to be formed in the channel substrate material.

The present disclosure provides a method including providing a chamber having a first inlet and a second inlet. A solution of a de-ionized (DI) water and an acid (e.g., a dilute acid) is provided to the chamber via the first inlet. A carrier gas (e.g., N2) is provided to the chamber via the second inlet. The solution and the carrier gas are in the chamber and then from the chamber onto a single semiconductor wafer. In an embodiment, the solution includes a dilute HCl and DI water.
摘要:
A semiconductor device and a method of manufacturing are provided. In some embodiments, a backside annealing process such that a first heat source is placed along a backside of the substrate. In other embodiments, the first heat source is used in combination with an anti-reflection dielectric (ARD) layer is deposited over the substrate. In yet other embodiments, a second heat source is placed along a front side of the substrate in addition to the first heat source placed on the backside of the substrate. In yet other embodiments, a heat shield may be placed between the substrate and the second heat source on the front side of the substrate. In yet further embodiments, a single heat source may be used on the front side of the substrate in combination with the ARD layer. A reflectivity scan may be performed to determine which anneal stage (RTA or MSA or both) to place thermal leveling solution.
摘要:
A method for fabricating an integrated device is disclosed. A protective layer is formed over a gate structure when forming epitaxial (epi) features adjacent to another gate structure uncovered by the protective layer. The protective layer is thereafter removed after forming the epitaxial (epi) features. The disclosed method provides an improved method for removing the protective layer without substantial defects resulting. In an embodiment, the improved formation method is achieved by providing a protector over an oxide-base material, and then removing the protective layer using a chemical comprising hydrofluoric acid.
