摘要： The invention comprises methods of forming a conductive contact to a source/drain region of a field effect transistor, and methods of forming local interconnects. In one implementation, a method of forming a conductive contact to a source/drain region of a field effect transistor includes providing gate dielectric material intermediate a transistor gate and a channel region of a field effect transistor. At least some of the gate dielectric material extends to be received over at least one source/drain region of the field effect transistor. The gate dielectric material received over the one source/drain region is exposed to conditions effective to change it from being electrically insulative to being electrically conductive and in conductive contact with the one source/drain region. Other aspects and implementations are contemplated.

摘要： A mass of material is formed over a semiconductor substrate. Semiconductive material is formed laterally proximate the mass of material. A space is provided laterally between the mass of material and the semiconductive material. The space comprises an outermost portion and a portion immediately adjacent thereto. The outermost portion has a maximum lateral width which is greater than that of the adjacent portion. Gate dielectric material and conductive gate material are formed within the space. The gate dielectric material and the conductive gate material in combination fill the adjacent portion of the space but do not fill the outermost portion of the space. At least the conductive gate material is etched from at least a majority of the outermost portion of the space. Source/drain regions are formed operatively proximate the conductive gate material and the semiconductive material is used as a channel region of the field effect transistor.

摘要： This invention includes gated field effect devices, and methods of forming gated field effect devices. In one implementation, a gated field effect device includes a pair of source/drain regions having a channel region therebetween. A gate is received proximate the channel region between the source/drain regions. The gate has a gate width between the source/drain regions. A gate dielectric is received intermediate the channel region and the gate. The gate dielectric has at least two different regions along the width of the gate. The different regions are characterized by different materials which are effective to define the two different regions to have different dielectric constants k. Other aspects and implementations are contemplated.
