    Abstract: A via having a unique barrier layer structure is provided. In an embodiment, a via is formed by forming a barrier layer in a via. The barrier layer along the bottom of the via is partially or completely removed, and the via is filled with a conductive material. In another embodiment, a first barrier layer is formed along the bottom and sidewalls of the via. Thereafter, the first barrier layer along the bottom of the via is partially or completely removed, and a second barrier layer is formed.

    Abstract: It is a general object of the present invention to provide an improved method of fabrication in the formation of an improved copper metal diffusion barrier layer having the structure, W/WSiN/WN, in single and dual damascene interconnect trench/contact via processing with 0.10 micron nodes for MOSFET and CMOS applications. The diffusion barrier is formed by depositing a tungsten nitride bottom layer, followed by an in situ SiH4/NH3 or SiH4/H2 soak forming a WSiN layer, and depositing a final top layer of tungsten. This invention is used to manufacture reliable metal interconnects and contact vias in the fabrication of MOSFET and CMOS devices for both logic and memory applications and the copper diffusion barrier formed, W/WSiN/WN, passes a stringent barrier thermal reliability test at 400° C. Pure single barrier layers, i.e., single layer WN, exhibit copper punch through or copper spiking during the stringent barrier thermal reliability test at 400° C.

    Abstract: A method includes forming a first oxide layer on a surface of an integrated heat spreader, and forming a second oxide layer on top surfaces of fins, wherein the fins are parts of a heat sink. The integrated heat spreader is bonded to the heat sink through the bonding of the first oxide layer to the second oxide layer.
