Abstract
Preferred embodiments grow a first diamondlike film (114) on a silicon substrate (102). Diamond film (116) is then grown on diamondlike film (114), the diamondlike film (114) providing a high density of nucleation sites (108) for the diamond film (116). Diamond film growth is interrupted and a second diamondlike film (134) is grown to provide a second region of nucleation sites (128). Second diamond film (126) is grown from nucleation sites (128), resulting in a relatively thick diamond film (140) with relatively small crystal grains.
