摘要:
A semiconductor structure is provided that includes a first metal resistor structure located on a portion of a dielectric-containing substrate. The first metal resistor structure includes, from bottom to top, a first nitridized dielectric surface layer portion having a first nitrogen content, a first metal portion, and a first dielectric capping layer portion. The semiconductor structure of the present application further includes a second metal resistor structure located on a second portion of the dielectric-containing substrate and spaced apart from the first metal resistor structure. The second metal resistor structure includes, from bottom to top, a second nitridized dielectric surface layer portion having a second nitrogen content that differs from the first nitrogen content, a second metal portion, and a second dielectric capping layer portion.
