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.

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.
