Patent ID: 7378318

Claim:
A method of modifying an operation of an integrated circuit device, comprising: identifying a first type of integrated circuit element, a second type of integrated circuit element and a third type of integrated circuit element, wherein operational characteristics of the first type of integrated circuit element are to be modified, operational characteristics of the third type of integrated circuit element are to be modified, and operational characteristics of the second type of integrated circuit element are to remain constant; depositing a first stress inducing film on the first, second and third type of integrated circuit element; applying a first masking layer to the first and second type of integrated circuit elements; stripping the first stress inducing film from the third type of integrated circuit element, wherein the first masking layer is applied prior to stripping the first stress inducing film from the third type of integrated circuit element and wherein the first stress inducing film applies a first stress to the first type of integrated circuit element to thereby change an operational characteristic of the first type of integrated circuit element; and depositing a second stress inducing film on the third type of integrated circuit element, wherein the second stress inducing film induces a second stress to the third type of integrated circuit element to thereby change an operational characteristic of the third type of integrated circuit element.
