    摘要: Disclosed is a procedure to coat the free surface of Cu damascene lines by a 1-5 nm thick element prior to deposition of the inter-level dielectric or dielectric diffusion barrier layer. The coating provides protection against oxidation, increases the adhesion strength between the Cu and dielectric, and reduces interface diffusion of Cu. In addition, the thin cap layer further increases electromigration Cu lifetime and reduces the stress induced voiding. The selective elements can be directly deposited onto the Cu embedded within the under layer dielectric without causing an electric short circuit between the Cu lines. These chosen elements are based on their high negative reduction potentials with oxygen and water, and a low solubility in and formation of compounds with Cu.

    摘要: A method and calibration standard for fabricating on a single substrate a series of crystalline pairs such that the d-spacing difference between the pairs will generate Moire fringes of the correct spacings to optimally calibrate the magnification settings of an electron microscope over a variety of magnification settings in the range of 5000× to 200,000×. The invention enables the tailoring of Moire fringe spacings to a desired magnification setting for calibration purposes by fabricating a series of patterns on a single substrate whereby each magnification setting is easily calibrated using a specific SGOI structure that is selected by a simple x-y translation across the top plan surface of the SGOI structure, therein eliminating the need for removing calibration samples in and out of the electron microscope. The method and calibration standard may be used for calibrating electron microscopes, such as, scanning transmission electron microscopes and transmission electron microscopes.

    摘要: This invention relates to a method for electrically localizing site-specific defective sub 130 nm node MOSFET devices with shallow (less than 80 nm deep) source/drain junctions utilizing bulk silicon, or Silicon on Insulator (SOI), or strained silicon (SE), followed by optimized sample preparation steps that permits imaging, preferably high resolution electron holographic imaging, in an electron microscope to detect blocked implants, asymmetric doping, or channel length variations affecting MOSFET device performance. Detection of such defects in such shallow junctions enables further refinements in process simulation models and permits optimization of MOSFET device designs.

    摘要: The present invention provides a method for forming an interconnect to a cobalt or nickel silicide having a TiN diffusion barrier. The inventive method comprises providing an initial structure having vias to exposed silicide regions positioned on a substrate; annealing the initial structure in a nitrogen-containing ambient, wherein a nitrogen passivation layer is formed atop the exposed silicide region; depositing Ti atop the nitrogen passivation layer; annealing the Ti in a nitrogen-containing ambient to form a TiN diffusion barrier and an amorphous Ti cobalt silicide between the TiN diffusion layer and the cobalt or nickel silicide and depositing an interconnect metal within the vias and atop the TiN diffusion barrier. The nitrogen passivation layer substantially restricts diffusion between the Ti and silicide layers minimizing the amorphous Ti cobalt silicide layer that forms. Therefore, the amorphous Ti cobalt or Ti nickel silicide is restricted to a thickness of less than about 3.0 nm.
