Chemical vapor deposition of tungsten for semiconductor metallization

  • 1. Bell Labs., Murray Hill, NJ

Description

Properties of CVD tungsten films produced by H2 reduction of the hexafluoride or hexachloride were investigated for suitability for use as Si integrated circuit metallizations. Adhesion, orientation, stress, and electric properties were measured. Excellent, low-resistance ohmic contacts were made to highly doped Si. The MOS characteristics of W/SiO2/Si structures were measured; they were nearly ideal when the hexachloride was used (MOS dots from the hexafluoride were usually shorted or leaky). (U.S.)
