ABSTRACT:
An electron-emitting device contains an electron focusing system (37 or 37A) formed with a base focusing structure (38 or 38A), a focus coating (39 or 39A), and an access conductor (106 or 116). The focus coating overlies the base focusing structure and extends into a focus opening (40). The access conductor is electrically coupled to the lower surface of the focus coating. A potential for controlling the focusing of electrons that travel through the focus opening is provided to the focus coating via the access conductor. The focus coating is typically formed by an angled deposition technique.
