    摘要: Methods of fabricating semiconductor devices and structures thereof are disclosed. In one embodiment, a method of manufacturing a semiconductor device includes forming a gate material stack over a workpiece having a first region and a second region. A composition or a thickness of at least one of a plurality of material layers of the gate material stack is altered in at least the second region. The gate material stack is patterned, forming a first transistor in the first region and forming a second transistor in the second region. Altering the composition or the thickness of the at least one of the plurality of material layers of the gate material stack in at least the second region results in a first transistor having a first threshold voltage and a second transistor having a second threshold voltage, the second threshold voltage having a different magnitude than the first threshold voltage.

    摘要: In a method of making a semiconductor device, a first gate stack is formed on a substrate at a pFET region, which includes a first gate electrode material. The source/drain regions of the substrate are etched at the pFET region and the first gate electrode material of the first gate stack is etched at the pFET region. The etching is at least partially selective against etching oxide and/or nitride materials so that the nFET region is shielded by a nitride layer (and/or a first oxide layer) and so that the spacer structure of the pFET region at least partially remains. Source/drain recesses are formed and at least part of the first gate electrode material is removed by the etching to form a gate electrode recess at the pFET region. A SiGe material is epitaxially grown in the source/drain recesses and in the gate electrode recess at the pFET region. The SMT effect is achieved from the same nitride nFETs mask.

    摘要: A method for fabricating a semiconductor device includes forming an SiGe region. The SiGe region can be an embedded source and drain region, or a compressive SiGe channel layer, or other SiGe regions within a semiconductor device. The SiGe region is exposed to an SC1 solution and excess surface portions of the SiGe region are selectively removed. The SC1 etching process can be part of a rework method in which overgrowth regions of SiGe are selectively removed by exposing the SiGe to and SC1 solution maintained at an elevated temperature. The etching process is carried out for a period of time sufficient to remove excess surface portions of SiGe. The SC1 etching process can be carried out at elevated temperatures ranging from about 25° C. to about 65° C.

In one embodiment, a method of fabricating a resistor includes forming a transistor material stack over a workpiece and patterning the transistor material stack, forming a gate of a transistor in a first region of the workpiece and leaving a portion of the transistor material stack in a second region of the workpiece. A top portion of the transistor material stack is removed in the second region, and a top portion of the workpiece is removed in the first region proximate the gate of the transistor, forming recessed regions in the workpiece in the first region. A semiconductive material is formed in the recessed regions of the workpiece in the first region and over a portion of the transistor material stack in the second region, forming a resistor in the second region.
