Abstract: A FinFET-type semiconductor device includes a fin structure on which a relatively thin amorphous silicon layer and then an undoped polysilicon layer is formed. The semiconductor device may be planarized using a chemical mechanical polishing (CMP) in which the amorphous silicon layer acts as a stop layer to prevent damage to the fin structure.

Abstract: A method for forming fin structures for a semiconductor device that includes a substrate and a dielectric layer formed on the substrate is provided. The method includes etching the dielectric layer to form a first structure, depositing an amorphous silicon layer over the first structure, and etching the amorphous silicon layer to form second and third fin structures adjacent first and second side surfaces of the first structure.

Abstract: A method of manufacturing a MOSFET type semiconductor device includes planarizing a gate material layer that is deposited over a channel. The planarization is performed in a multi-step process that includes an initial “rough” planarization and then a “fine” planarization.
