Abstract: Methods are disclosed that fabricating semiconductor devices with high-k dielectric layers. The invention removes portions of deposited high-k dielectric layers not below gates and covers exposed portions (e.g., sidewalls) of high-k dielectric layers during fabrication with an encapsulation layer, which mitigates defects in the high-k dielectric layers and contamination of process tools. The encapsulation layer can also be employed as an etch stop layer and, at least partially, in comprising sidewall spacers. As a result, a semiconductor device can be fabricated with a substantially uniform equivalent oxide thickness.

Abstract: A method of forming a semiconductor circuit (20). The method forms a first transistor (NT1) using various steps, such as by forming a first source/drain region (361) as a first doped region in a fixed relationship to a semiconductor substrate (22) and forming a second source/drain region (362) as a second doped region in a fixed relationship to the semiconductor substrate. The second doped region and the first doped region are of a same conductivity type. Additionally, the first transistor is formed by forming a first gate (283) in a fixed relationship to the first source/drain region and the second drain region. The method also forms a second transistor (ST1) using various steps, such as by forming a third source/drain region (341) as a third doped region in a fixed relationship to the semiconductor substrate and forming a fourth source/drain region (342) as a fourth doped region in a fixed relationship to the semiconductor substrate.
