摘要
The present invention relates to complementary metal-oxide-semiconductor (CMOS) circuits, as well as methods for forming such CMOS circuits. More specifically, the present invention relates to CMOS circuits that contain passive elements, such as buried resistors, capacitors, diodes, inductors, attenuators, power dividers, and antennas, etc., which are characterized by an end contact resistance of less than 90 ohm-microns. Such a low end resistance can be achieved either by reducing the spacer widths of the passive elements to a range of from about 10 nm to about 30 nm, or by masking the passive elements during a pre-amorphization implantation step, so that the passive elements are essentially free of pre-amorphization implants.
