Thermal budgeting in a double level metal process with CVD tungsten as first metal

  • 1. Texas Instruments, Inc., Dallas, TX (USA)

Description

The high temperature stability of CVD tungsten interconnects over TiSi/sub 2/-clad diffusions was tested up to 7000C. A sputtered 10 wt. % Ti in W sticking layer was used to nucleate the W. Contact resistance was stable at the highest temperatures, and measured < 0.01 μohm-cm/sup 2/. Junction leakage decreased from /sup --/50 na/cm/sup 2/ to < 5 na/cm/sup 2/ upon 7000C annealing of both p/sup +//n/sup -/ and n/sup +//p/sup -/ diodes
