摘要:
Semiconductor devices, methods of manufacture thereof, and methods of forming resistors are disclosed. In one embodiment, a method of manufacturing a semiconductor device includes forming a first insulating material over a workpiece, and forming a conductive chemical compound material over the first insulating material. The conductive chemical compound material is patterned to form a resistor. A second insulating material is formed over the resistor, and the second insulating material is patterned. The patterned second insulating material is filled with a conductive material to form a first contact coupled to a first end of the resistor and to form a second contact coupled to a second end of the resistor.
摘要:
A method of fabricating a semiconductor device is disclosed. The method includes providing a substrate including an isolation region, forming a resistor over the isolation region, and forming a contact over the resistor. The method also includes implanting with a dopant concentration that is step-increased at a depth of the resistor and that remains substantially constant as depth increases.

A device includes a substrate and a recess in the substrate. The recess has a bottom and sidewalls. The device also includes a first epitaxial layer over the bottom of the recess, and a second epitaxial layer over the first epitaxial layer and over the sidewalls of the recess, the second epitaxial layer having a different lattice constant than the substrate. The device further includes a third epitaxial layer over the second epitaxial layer and filling the recess.
