摘要: A method for improving the gate activation of metal oxide semiconductor field effect transistor (MOSFET) structures are provided. The method of the present invention includes the steps of forming a plurality of patterned gate stacks atop a layer of gate dielectric material; forming a first planarizing organic film on the gate dielectric material and abutting vertical sidewalls of the patterned gate stacks, said planarizing organic film not being present on top, horizontal surfaces of each of the patterned gate stacks; blocking some of the plurality of patterned gate stacks with a first resist, while leaving other patterned gate stacks of said plurality unblocked; implanting first ions into the unblocked patterned gate stacks; removing the first resist and first planarizing organic film and forming a second planarizing organic film and blocking the previously unblocked patterned gate stacks with a second resist; implanting second ions into the patterned gate stacks that are not blocked by said second resist; and removing the second resist and the second planarizing organic film.

摘要: Thermal degradation of a low-k organic dielectric material is avoided or limited in the proximity of a heat source such as a fusible element by overlaying the low-k material with a thermally conductive material and providing a low thermal resistance path from the thermally conductive material, possibly having a low modulus of elasticity, to a heat sink. The thermally conductive material thus provides crack-stop protection for further layers of an integrated circuit or interconnect structure above the fusible element by mechanical, chemical and thermal encapsulation of the heat source and low-k material.

摘要: In an integrated circuit process for SOI including trench device isolation, the problem of voids in the trench fill is addressed by a triple fill process, in which a thermal oxide sidewall having recesses at the bottom corners is covered with a LPCVD deposition that fills in the recesses, followed by a void-free HDP deposition. Densification results in substantially the same etch rate for the three types of oxide.
