  • Abstract
    In this paper we demonstrate the feasibility of direct electroless plating of copper in the NITD system with in-situ annealing treatment. As a result of the high temperature effect during deposition, the peak ratio of Cu (111 )/Cu (200) of copper film reached 19. The resistivity of as-deposited Cu layer was as low as 2.45 muOmega-cm. The NTID system, using single step to deposit metal film, has several advantages that can discard the post-annealing and simplify the deposition processes. It has potential for the application on ULSI.
