Abstract:
1. A method of improving reliability of a semiconductor device comprising at least one layer of low-K ILD, steps of which comprise: providing a semiconductor device comprising: providing a heat curable composition either between the electrically interconnected surfaces of the semiconductor chip and the carrier substrate to form a semiconductor device assembly and/or over the semiconductor device assembly; and exposing the semiconductor device assembly to elevated temperature conditions sufficient to cure the heat curable composition, wherein the heat curable composition comprises a curable resin component and a filler component, wherein the filler component is present in an amount sufficient to provide the heat curable composition when cured with a coefficient of thermal expansion of less than about 25 ppm/° C. or a coefficient of thermal expansion of greater than about 50 ppm/° C. and when cured the heat curable composition has a ratio of modulus versus temperature between −65° C. and 125° C. in the range of 10 MPa/° C. to about −10 MPa/° C.
