    摘要: A method of forming a semiconductor structure includes forming at least one trench in an insulator layer formed on a substrate. A distance between a bottom edge of the at least one trench and a top surface of a substrate is shorter than a distance between an uppermost surface of the insulator layer and the top surface of the substrate. The method also includes: forming a resistor on the insulator layer and extending into the at least one trench; forming a first contact in contact with the resistor; and forming a second contact in contact with the resistor such that current is configured to flow from the first contact to the second contact through a central portion of the resistor.

    摘要: Disclosed herein are various methods and structures using contacts to create differential stresses on devices in an integrated circuit (IC) chip. An IC chip is disclosed having a p-type field effect transistor (PFET) and an n-type field effect transistor (NFET), a PFET contact to a source/drain region of the PFET and an NFET contact to a source/drain region of the NFET. In a first embodiment, a silicon germanium (SiGe) layer is included only under the PFET contact, between the PFET contact and the source/drain region of the PFET. In a second embodiment, either the PFET contact extends into the source/drain region of the PFET or the NFET contact extends into the source/drain region of the NFET.
