NUCLEATION AND GROWTH OF Cu THIN FILMS ON SILICON BASE INDUCED BY EXCIMER LASER ANNEALING

Abstract: The  initial    growth  of  Cu  nucleation  and  its  development  on  silicon  base  prepared  by  Pressure Vapor  Deposition  PVD  was  investigated  by  Atomic  Force  Microscopy.  Experimental  results  indicate  that amorphous  silicon  copper  film  poorly  crystallized  after  heat  treatment  by  conventional  furnace  after  four hours.  Immediately  after  annealing  by  single  exposure  of  UV  excimer  laser,  the  crystalline  become apparently  increases.  The  rapid  solidification  has  passing  the  recalesence  point  to  spontaneously  form crystalline  pattern.  The  increasing  of  heat  transfer  enlarged  crystalline  to  the  maximum  at  super  lateral growth energy of 345 Jcm-2. The agglomeration and coalescation of grains are the reason for the increment of the surface roughness.
