  • Publication number: 20090311855
    Abstract: A method of fabricating a gate structure in a metal oxide semiconductor field effect transistor (MOSFET) and the structure thereof is provided. The MOSFET may be n-doped or p-doped. The gate structure, disposed on a substrate, includes a plurality of gates. Each of the plurality of gates is separated by a vertical space from an adjacent gate. The method deposits at least one dual-layer liner over the gate structure filling each vertical space. The dual-layer liner includes at least two thin high density plasma (HDP) films. The deposition of both HDP films occurs in a single HDP chemical vapor deposition (CVD) process. The dual-layer liner has properties conducive for coupling with plasma enhanced chemical vapor deposition (PECVD) films to form tri-layer or quadric-layer film stacks in the gate structure.

  • Patent number: 7326651
    Abstract: This invention relates to the manufacture of dual damascene interconnect structures in integrated circuit devices. Specifically, a method is disclosed for forming a single or dual damascene structure in a low-k dielectric thin film utilizing a planarizing material and a compressive diffusion barrier material. The barrier material preferably has a compressive stress of greater than 300 MPa. In a preferred dual damascene embodiment of this method, the vias are formed first in the dielectric material, then the planarizing material is deposited in the vias and on the dielectric material, and the barrier material is deposited on the planarizing material. The trenches are then formed lithographically in the imaging material, etched through the barrier material into the planarizing material, and the trench pattern is transferred to the dielectric material. During and following the course of these etch steps, the imaging, barrier and planarizing materials are removed.
