Abstract :
A highly thermally stable shallow p+/n junction has been fabricated. it was found that N2+ pre-implantation can lead to a significant stabilisation of CoSi2 films during high temperature annealing. TEM delineation results confirm that the CoSi2 film remains smooth and uniform with the N2+ pre-implantation while agglomeration occurs on the non-N2+-implanted sample
