    Abstract: An apparatus and method for mapping film thickness of one or more textured polycrystalline thin films. Multiple sample films of known thickness are provided. Each sample film is irradiated by x-ray at a measurement point to generate a diffraction image that captures a plurality of diffraction arcs. Texture information (i.e., pole densities) of the sample film is calculated based on incomplete pole figures collected on the diffraction image and used to correct the x-ray diffraction intensities from such sample. The corrected diffraction intensities are integrated for each sample film, and then used for constructing a calibration curve that correlates diffraction intensities with respective known film thickness of the sample films. The film thickness of a textured polycrystalline thin film of unknown thickness can therefore be mapped on such calibration curve, using a corrected and integrated diffraction intensity obtained for such thin film of unknown thickness.

    Abstract: Grooves (70, 76, 78, & 80-82) are formed in a CMP pad (12) by positioning the pad (12) on a supporting surface (10) with a working surface (22) of the pad (12) in spaced relation opposite to a router bit (24) and at least one projecting stop member (33) adjacent to the router bit (24), an outer end portion of the bit (24) projecting beyond the stop (33). When the bit (24) is rotated, relative axial movement between the bit (24) and the pad (12) causes the outer end portion of the bit (24) to cut an initial recess in the pad (12). Relative lateral movement between the rotating bit (24) and the pad (12) then forms a groove (70) which extends laterally away from the recess and has a depth substantially the same as that of the recess. The depths of the initial recess and the groove (70) are limited by applying a vacuum to the working surface (22) of the pad (12) to keep it in contact with the stop member(s) (33). Different lateral movements between the bit (24) and the pad (12) are used to form a variety of groove patterns (76, 78, & 80-82), the depths of which are precisely controlled by the stop member(s) (33).

    Abstract: PROBLEM TO BE SOLVED: To obtain a new barrier layer which fulfills all standards by forming an alpha phase tungsten barrier layer in a trench or a via, having a mutual bonding structure by using a chemical low temperature/low pressure air phase adhesion technology. SOLUTION: A dielectric 22 is formed on a semiconductor substrate 20 and a trench or a via having a mutual bonding structure is formed on the surface of the dielectric 22. An alpha phase tungsten barrier layer 24 is formed in the trench or the via through the use of chemical low temperature/low pressure air phase adhesion technology method and an arbitrarily selected metallic seed layer 26 is laminated and formed thereon. Additionally conductive material 28 is embedcred in the trench or the via and an alpha phase tungsten barrier layer 25, a dielectric 30 and an electrode 32 are successively formed thereon. In this case a barrier layer 36, made of such materials as alpha tungsten and so on which protects a contact of the conductor 28 with the dielectric 22, is formed.
