    Abstract: A method for producing a small feature in a semiconductor device includes depositing a mask material on an unpatterned layer in which an ultra-narrow opening is to be formed, and then masking and etching the mask material to form a narrow opening. A spacer material is then deposited on the mask material, with spacer material settling into and covering the narrow opening. Thereafter, a portion of the spacer material is removed by etching, leaving some spacer material in the opening but exposing an ultra-narrow region of the first layer at the bottom of the opening in the mask material. The ultra-narrow region left uncovered by the spacer material is smaller than the narrow region in the mask material. Once the ultra-narrow region is uncovered, material in the first layer is removed through the ultra-narrow region, by anisotropic etching, for example, to form an ultra-narrow opening in the first layer.

    Abstract: A dual damascene method of fabricating an interconnection level of conductive lines and connecting vias separated by insulation for integrated circuits and substrate carriers for semiconductor devices using a thin protective via mask to form the via openings. A conductive line mask pattern is used to form conductive line openings in an insulating layer. Next, a thin protective layer of conformal material is deposited in the conducive line opening. The protective layer and the insulating layer each have etch resistance to others etchant. Using a via mask pattern, openings are etching the protective layer with the insulating layer serving as and etch stop. Next via openings are etched in the insulating material using the openings in the thin protective layer as the etch mask. If the protective layer is a conductive material, it is removed from the surface of the insulating layer either before or after the conductive line and via openings are filled with a conductive material. If the protective material is an insulating material, it is entirely removed before filling the conductive line and via openings conductive material.

    Abstract: 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.
