Patent ID: 8461589

Claim:
An integrated circuit (IC), comprising: a substrate having a topside semiconductor surface having active circuitry and passive circuitry configured to provide a circuit function; a pre-metal dielectric (PMD) layer on said topside semiconductor surface; a metal interconnect stack on said PMD layer comprising a plurality of metal interconnect levels having interlevel dielectric layers (ILDs) therebetween; a trim portion including one or more temperature sensitive circuit components which affect a temperature behavior of said IC; a heated portion extending over and beyond an area of said trim portion having an integrated heating structure, said integrated heating structure including: at least a first heater formed from a first of said plurality of metal interconnect levels comprising a first plurality of winding segments which have a varying pitch; a heat spreader formed from a second of said plurality of metal interconnect layers between said trim portion and said first heater, and a plurality of thermal plugs lateral to said temperature sensitive circuit component thermally coupling said heat spreader to said topside semiconductor surface.
