    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.

    Abstract: PROBLEM TO BE SOLVED: To provide a metallization structure, which is small in resistivity, has excellent electricity transfer characteristics and at the same time, is textured to a high degree, and moreover, to prevent the formation of a hillock on the structure by a method wherein aluminium layers, aluminium alloy layers or both layers of the aluminium layers and the aluminum alloy layers, which come into contact electrically with tower group IVA metal layers having a thickness in a specified range, are formed. SOLUTION: Four or five-layer interconnected metallized layers are formed on interlayer stud connection layers 10, which are encircled with an insulator 8 and are connected with a silicon substratelike device substrate 6. Lower group IVA metal layers 13 consist of a titanium layer and the thickness of a metallization structure is about 90 to about 110 angstroms. By limiting this thickness, the structure of a metal layer, which is added afterwards, and the texture of the metal layer are controlled. Layers 15 to come into contact electrically with the lower layers 13 are aluminium layers or aluminium alloy layers. Titanium nitride layers 14 on the lower layers 13 prevent a reaction of the aluminium layers 15 with the lower layers 13 and capping layers consisting of titanium layers 18 and titanium nitride layers 19 perform an antireflection action.

    Abstract: Grooves are formed in a CMP (12) pad by positioning the pad on a supporting surface with a working surface (22) of the pad in spaced relation opposite to a router bit (24) and at least one projecting stop member (33) adjacent to the router bit, an outer end portion of the bit projecting beyond the stop. When the bit is rotated, relative axial movement between the bit and the pad causes the outer end portion of the bit to cut an initial recess in the pad. Relative lateral movement between the rotating bit and the pad then forms a groove which extends laterally away from the recess and has a depth substantially the same as that of the recess. Different lateral movements between the bit and the pad are used to form a variety of groove patterns, the depths of which are precisely controlled by the stop member(s). The grooves may be formed in the polishing surface and/or the rear opposite surface of the pad and passages may be provided for interconnecting the rear grooves with the polishing surface or the front grooves. Grooves in the polishing surface may be provided with outlets through which a polishing slurry may flow while the polishing surface is in contact with a workpiece surface.
