Apparatus for determining a best trajectory for laser CVD through a strategy of acquiring a series of two-dimensional plane images of the substrate. These images, taken together, contain topographical information as well as local reflectivity and thermal mapping information. The images are combined in digital format with additional substrate mapping information to calculate a best three-dimensional trajectory for the desired laser operation. The technique is especially suitable for compensation of tilt or severe height variation on microelectronic parts. The apparatus can deposit platinum conductors on integrated circuits by pyrolytic deposition from Pt(PF3)4 vapor.
