Abstract:
A method of forming a semiconductor device, includes forming a conductive layer in a recessed portion of a porous dielectric layer, partially removing a top portion of the conductive layer while maintaining a height of the porous dielectric layer, forming a conformal cap layer on the porous dielectric layer and the conductive layer in the recessed portion, polishing the conformal cap layer to form a gap in the conformal cap layer, such that an upper surface of the porous dielectric layer is exposed through the gap and an upper surface of the conductive layer is protected by the cap layer, and performing a heat treatment to burn out a pore filler of the porous dielectric layer through the exposed upper surface of the porous dielectric layer.

Claim (Index 12):
A method of forming a semiconductor device, comprising:\n forming a porous dielectric layer on an interconnect layer; forming a recessed portion in the porous dielectric layer; depositing a metal on the porous dielectric layer and in the recessed portion; polishing the metal and the porous dielectric layer; etching the metal in the recessed portion and the porous dielectric layer to form a metal layer in the recessed portion; forming a conformal cap layer on the etched porous dielectric layer and the etched metal in the recessed portion; polishing the conformal cap layer to form a gap in the conformal cap layer, such that an upper surface of the porous dielectric layer is exposed through the gap, the gap comprising a length which is greater than an average pore diameter of the pores the porous dielectric layer; and performing a heat treatment to burn out a pore filler of the porous dielectric layer through the exposed upper surface of the porous dielectric layer, a temperature of the heat treatment being in a range from 200\u00b0 C. to 450\u00b0 C., and duration of the heat treatment being in a range from 1 minute to 30 minutes.
