    摘要: 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.

    摘要: A structure and method of forming an improved metal cap for interconnect structures is described. The method includes forming an interconnect feature in an upper portion of a first insulating layer; deposing a dielectric capping layer over the interconnect feature and the first insulating layer; depositing a second insulating layer over the dielectric capping layer; etching a portion of the second insulating layer to form a via opening, wherein the via opening exposes a portion of the interconnect feature; bombarding the portion of the interconnect feature for defining a gauging feature in a portion of the interconnect feature; etching the via gauging feature for forming an undercut area adjacent to the interconnect feature and the dielectric capping layer; depositing a noble metal layer, the noble metal layer filling the undercut area of the via gauging feature to form a metal cap; and depositing a metal layer over the metal cap.

    摘要: An interconnect structure having improved electromigration (EM) reliability is provided. The inventive interconnect structure avoids a circuit dead opening that is caused by EM failure by incorporating a EM preventing liner at least partially within a metal interconnect. In one embodiment, a “U-shaped” EM preventing liner is provided that abuts a diffusion barrier that separates conductive material from the dielectric material. In another embodiment, a space is located between the “U-shaped” EM preventing liner and the diffusion barrier. In yet another embodiment, a horizontal EM liner that abuts the diffusion barrier is provided. In yet a further embodiment, a space exists between the horizontal EM liner and the diffusion barrier.

    摘要: A cap nitride stack which prevents etch penetration to the HDP nitride while maintaining the electromigration benefits of HDP nitride atop Cu. In one embodiment, the stack comprises a first layer of HDP nitride and a second layer of a Si—C—H compound disposed over the first layer. The Si—C—H compound is for example BLoK, or N-BLoK (Si—C—H—N), and is selected from a group of materials that has high selectivity during via RIE such that RIE chemistry from the next wiring level does not punch through. Carbon and nitrogen are the key elements. In another embodiment, the stack comprises a first layer of HDP nitride, followed by a second layer of UVN (a plasma nitride), and a third layer comprising HDP nitride disposed over the second layer.

    摘要: Disclosed is a method and structure for forming a silicide on a silicon material. The invention places the silicon material in a vacuum environment, forms metal on the silicon material, and then heats the silicon surface and the metal without breaking the vacuum environment. The processes of forming the metal and heating the silicon can be performed simultaneously without breaking the vacuum environment to form the silicide as the metal is being deposited. After the foregoing processing, the invention can remove the silicon surface from the vacuum environment and perform additional heating of the silicon surface. The first heating process forms a monosilicide and the additional heating forms a disilicide.
