    摘要: 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. The second and third fin structures may include amorphous silicon material. The method further includes depositing a metal layer on upper surfaces of the second and third fin structures, performing a metal-induced crystallization operation to convert the amorphous silicon material of the second and third fin structures to a crystalline silicon material, and removing the first structure.

    摘要: A method of forming fins for a double-gate fin field effect transistor (FinFET) includes forming a second layer of semi-conducting material over a first layer of semi-conducting material and forming double caps in the second layer of semi-conducting material. The method further includes forming spacers adjacent sides of each of the double caps and forming double fins in the first layer of semi-conducting material beneath the double caps. The method also includes thinning the double fins to produce narrow double fins.

    摘要: A method of manufacturing semiconductor fins for a semiconductor device may begin by providing a bulk semiconductor substrate. The method continues by growing a layer of first epitaxial semiconductor material on the bulk semiconductor substrate, and by growing a layer of second epitaxial semiconductor material on the layer of first epitaxial semiconductor material. The method then creates a fin pattern mask on the layer of second epitaxial semiconductor material. The fin pattern mask has features corresponding to a plurality of fins. Next, the method anisotropically etches the layer of second epitaxial semiconductor material, using the fin pattern mask as an etch mask, and using the layer of first epitaxial semiconductor material as an etch stop layer. This etching step results in a plurality of fins formed from the layer of second epitaxial semiconductor material.
