Patent ID: 7179758

Claim:
A method for restoring properties of a low k or very low dielectric constant organosilicate film having hydrogen atoms or alkyl or aryl groups attached to silicon atoms, and used in a low or very low dielectric constant insulating layer in a semiconductor chip, or chip carrier, or a semiconductor wafer wherein said organosilicate film has undergone processing tending to degrade the properties, the method comprising: applying to the film a silylating agent comprising an aminosilane, so as to restore dielectric properties of the film, wherein the aminosilane has the general formula (R 2 N) x SiR′ Y R″ Z where X, Y and Z are integers with x varying from 1 to 3, and Y and Z varying from 3 to 0 respectively but where x+y+z is always equal to 4, and where R, R′, and R″ are any hydrogen, methyl, aryl, allyl, phenyl or vinyl moiety.
