Abstract

A process for fabricating integrated resistors in high density interconnect substrates for multi-chip modules. In addition, the resistor material can be converted selectively into an insulator for optionally allowing for the simultaneous fabrication of integrated resistors and capacitors in relatively few steps. The process is well suited for copper/polyimide substrates.
