Abstract
A method includes forming a first plurality of gate structures. A second plurality of gate structures is formed. A first spacer is formed on each of the first and second pluralities of gate structures. A first cavity is defined between the first spacers of a first pair of the first plurality of gate structures. A second cavity is defined between the first spacers of a second pair of the second plurality of gate structures. A second spacer is selectively formed in the second cavity on the first spacer of each of the gate structures of the second pair without forming the second spacer in the first cavity. A first contact is formed contacting the first spacers in the first cavity. A second contact is formed contacting the second spacers in the second cavity.
