摘要: An apparatus for monitoring an ion distribution of a wafer comprises a first sensor and a sensor. The first sensor, the second sensor and the wafer are placed in an effective range of a uniform ion implantation current profile. A controller determines the ion dose of each region of the wafer based upon the detected signal from the first sensor and the second sensor. In addition, the controller adjusts the scanning frequency of an ion beam or the movement speed of the wafer to achieve a uniform ion distribution on the wafer.

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.

摘要: Semiconductor materials, particularly III-V materials used to form, e.g., a finlike structure can suffer structural damage during chemical mechanical polishing steps. This damage can be reduced or eliminated by oxidizing the damaged surface of the material and then etching away the oxidized material. The etching step can be accomplished simultaneously with a step of etching back a patterned oxide layers, such as a shallow trench isolation layer.
