Patent ID: 8324093

Claim:
A method for fabricating a semiconductor device, comprising the steps of: providing a partially-completed semiconductor device including a first feature formed in a porous material; wet cleaning the partially-completed semiconductor device with an aqueous cleaning solvent, wherein a quantity of the aqueous cleaning solvent diffuses into a body portion of the porous material; removing the aqueous cleaning solvent from the partially-completed semiconductor device, wherein residual water remains in the body portion of the porous material; exposing the partially-completed semiconductor device to a liquid chemical that is substantially depleted of water such that the liquid chemical diffuses into the body portion of the porous material and mixes with the residual water to form an azeotropic mixture in the body portion of the porous material; and inducing evaporation of the azeotropic mixture to remove the residual water from the body portion of the porous material, wherein the step of inducing comprises placing the partially-completed semiconductor device under partial vacuum.
