    • A method of forming a polycrystalline film, such as a diamond, on a foreign substrate involves preparing the substrate before film deposition to define discrete nucleation sites. The substrate is prepared for film deposition by forming a pattern of irregularities in the surface thereof. The irregularities, typically craters, are arranged in a predetermined pattern which corresponds to that desired for the location of film crystals. The craters preferrably are of uniform, predetermined dimensions (in the sub-micron and micron size range) and are uniformly spaced apart by a predetermined distance. The craters may be formed by a number of techniques, including focused ion beam milling, laser vaporization, and chemical or plasma etching using a patterned photoresist. Once the substrate has been prepared the film may be deposited by a number of known techniques. Films prepared by this method are characterized by a regular surface pattern of crystals which may be arranged in virtually any desired pattern. Diamond film materials made by this technique may be used in many electrical, optical, thermal and other applications.
    • 在异物基底上形成诸如金刚石的多晶膜的方法包括在膜沉积之前制备基底以限定离散的成核位点。 通过在其表面上形成不规则图案来制备用于膜沉积的衬底。 不规则形状(通常为凹坑)以与薄膜晶体的位置所期望的对应的预定图案排列。 凹坑优选地具有均匀的预定尺寸(亚微米和微米尺寸范围),并且均匀间隔开预定距离。 凹坑可以通过许多技术形成,包括聚焦离子束研磨,激光蒸发和使用图案化的光致抗蚀剂的化学或等离子体蚀刻。 一旦制备了基底,可以通过多种已知技术沉积该膜。 通过该方法制备的膜的特征在于可以以几乎任何所需图案布置的规则的晶体表面图案。 通过该技术制造的金刚石膜材料可用于许多电气,光学,热学和其他应用中。
