1. A complementary metal-oxide-semiconductor (CMOS) device, comprising:
a first transistor with a first conductivity type, wherein the first transistor comprises:
a first source region and a first drain region; and
a first metal over and in contact with the first source region and the first drain region; and
a second transistor with a second conductivity type opposite from the first conductivity type, wherein the second transistor comprises:
a second source region and a second drain region;
a second metal over and in contact with the second source region and the second drain region; and
the first metal over and in contact with the second metal, the first metal different than the second metal, and the first metal in contact with the second source region and the second drain region.
