Abstract:
A diamond field emitter fabrication method, comprising:pretreating a surface of an Si substrate using diamonds; depositing an SiO2 oxide film on the pretreated Si substrate and coating a photo resist film thereon; selectively etching the SiO2 oxide film using a mask of a predetermined pattern; etching a portion of the surface of the Si substrate, which is exposed by said etching of the SiO2 oxide film, so that the pretreated surface of the Si substrate under a portion of the SiO2 oxide film which is not etched has a predetermined width; performing a plasma treatment for an etched portion of the surface of the Si substrate; removing the remaining SiO2 oxide film; and depositing a diamond on the pretreated surface of the Si substrate, which is not etched.
