Abstract:
Dummy Micro-Electro-Mechanical System (MEMS) structures, methods of manufacture and design structures are disclosed. The method includes forming a bumper extending from a Micro-Electro-Mechanical System (MEMS) beam structure provided within a cavity structure. The method further includes forming a dummy landing structure on an opposing side of the cavity structure from the MEMS beam, which is laterally offset from the bumper when the MEMS beam is in a non-actuated state.
Abstract:
An array of through substrate vias (TSVs) is formed through a semiconductor substrate and a contact-via-level dielectric layer thereupon. A metal-wire-level dielectric layer and a line-level metal wiring structure embedded therein are formed directly on the contact-via-level dielectric layer. The line-level metal wiring structure includes cheesing holes that are filled with isolated portions of the metal-wire-level dielectric layer. In one embodiment, the entirety of the cheesing holes is located outside the area of the array of the TSVs to maximize the contact area between the TSVs and the line-level metal wiring structure. In another embodiment, a set of cheesing holes overlying an entirety of seams in the array of TSVs is formed to prevent trapping of any plating solution in the seams of the TSVs during plating to prevent corrosion of the TSVs at the seams.
Abstract:
A through substrate via includes an annular conductor layer at a periphery of a through substrate aperture, and a plug layer surrounded by the annular conductor layer. A method for fabricating the through substrate via includes forming a blind aperture within a substrate and successively forming and subsequently planarizing within the blind aperture a conformal conductor layer that does not fill the aperture and plug layer that does fill the aperture. The backside of the substrate may then be planarized to expose at least the planarized conformal conductor layer.

PROBLEM TO BE SOLVED: To provide a method for forming a low-resistive interconnect structure on and in a rigid low-k interlayer dielectric layer. SOLUTION: The method comprises the steps of providing a lower metal wiring layer having first metal lines 26 positioned within a lower low-k dielectric 32, depositing an upper low-k dielectric 6 on the lower metal wiring layer, etching at least one portion of the upper low-k dielectric to provide at least one via 24 to the first metal lines, forming rigid dielectric sidewall spacers 12 in at least one via of the upper low-k dielectric, and forming second metal lines 25 in at least one portion of the upper low-k dielectric.
