    Abstract: An n-channel MISFETQn is formed in an nMIS first formation region of a semiconductor substrate and a p-channel MISFETQp is formed in an adjacent pMIS second formation region of the semiconductor substrate. A silicon nitride film having a tensile stress is formed to cover the n-channel MISFETQn and the p-channel MISFETQp. In one embodiment, the silicon nitride film in the nMIS formation region and the pMIS formation region is irradiated with ultraviolet rays. Thereafter, a mask layer is formed to cover the silicon nitride film in the nMIS formation region and to expose the silicon nitride film in the pMIS formation region. The silicon nitride film in the pMIS formation region is then subjected to plasma processing, which relieves the tensile stress of the silicon nitride film in the pMIS formation region.

  • Patent number: 8629053
    Abstract: A semiconductor device having a polymer layer and a method of fabricating the same is provided. A two-step plasma treatment for a surface of the polymer layer includes a first plasma process to roughen the surface of the polymer layer and loosen contaminants, and a second plasma process to make the polymer layer smoother or make the polymer layer less rough. An etch process may be used between the first plasma process and the second plasma process to remove the contaminants loosened by the first plasma process. In an embodiment, the polymer layer exhibits a surface roughness between about 1% and about 8% as measured by Atomic Force Microscopy (AFM) with the index of surface area difference percentage (SADP) and/or has surface contaminants of less than about 1% of Ti, less than about 1% of F, less than about 1.5% Sn, and less than about 0.4% of Pb.

    Abstract: An apparatus having a three-dimensional integrated circuit structure is described herein. The apparatus include an interposer for carrying a plurality of high and low-power chips. The high-power chips are attached and connected to one side of the interposer, while the low-power chips are attached and connected to the other side of the interposer. In generally, the high-power chips produce more heat than does the low-power chip during their operations. The interposer further include through silicon vias and redistribution layers for connecting the chips on both surfaces. In addition, the interposer assembly is attached and connected to a substrate layer, which is in turn attached and connected to a printed circuit board. In order to provide improve thermal management, the interposer surface carrying the high-power chips are oriented away from the circuit board. A heat spreader is attached to the back sides of the high-power chips for dissipating the heat.
