Abstract:
A method of fabricating a semiconductor device, comprising the steps of:isolating a first region of a semiconductor layer from a second region of the semiconductor layer;forming a first disposable gate structure of a first transistor over the first region of the semiconductor layer;forming a second disposable gate structure of a second transistor over the second region of the semiconductor layer;forming a capping layer over the first and second regions except over a portion of the first and second disposable gate structures;forming a second disposable gate cap over the exposed portion of the second disposable gate structure;removing at least part of the first disposable gate structure; andafter removing at least a part of the first disposable gate structure and prior to removing the second disposable gate cap, depositing a first gate body material of a first gate structure of the first transistor in place of the removed part of the first disposable gate structure.
