Stress of a silicon nitride layer may be enhanced by deposition at higher temperatures. Employing an apparatus that allows heating of a substrate to substantially greater than 400° C. (for example a heater made from ceramic rather than aluminum), the silicon nitride film as-deposited may exhibit enhanced stress allowing for improved performance of the underlying MOS transistor device. In accordance with some embodiments, a deposited silicon nitride film is exposed to curing with plasma and ultraviolet (UV) radiation, thereby helping remove hydrogen from the film and increasing film stress. In accordance with other embodiments, a silicon nitride film is formed utilizing an integrated process employing a number of deposition / curing cycles to preserve integrity of the film at the sharp corner of the underlying raised feature. Adhesion between successive layers may be promoted by inclusion of a post-UV cure plasma treatment in each cycle.

In a stacked chip configuration, and manufacturing methods thereof, the gap between a lower chip and an upper chip is filled completely using a relatively simple process that eliminates voids between the lower and upper chips and the cracking and delamination problems associated with voids. The present invention is applicable to both chip-level bonding and wafer-level bonding approaches. A photosensitive polymer layer is applied to a first chip, or wafer, prior to stacking the chips or stacking the wafers. The photosensitive polymer layer is partially cured, so that the photosensitive polymer layer is made to be structurally stable, while retaining its adhesive properties. The second chip, or wafer, is stacked, aligned, and bonded to the first chip, or wafer, and the photosensitive polymer layer is then cured to fully bond the first and second chips, or wafers. In this manner, adhesion between chips / wafers is greatly improved, while providing complete fill of the gap. In addition, mechanical reliability is improved and CTE mismatch is reduced, alleviating the problems associated with warping, cracking and delamination, and leading to an improvement in device yield and device reliability.
