Abstract:
PROBLEM TO BE SOLVED: To provide a diamond electron source and its manufacturing method wherein one sharp-pointed section as an electron emission point for use in an electron beam device such as an electron microscope is formed at one end of a columnar diamond single crystal having a size where resist coating is difficult in a microfabrication process. SOLUTION: One end of the columnar diamond single crystal 10 is polished to form a smooth flat surface 11, and a ceramic layer 12 is formed on the smooth flat surface 11. After a thin film layer 14 having a predetermined shape is deposited on the ceramic layer 12 by using a focused ion beam system, the ceramic layer 12 is patterned by etching using the thin film layer 14 as a mask. One sharp-pointed section is formed at the one end of the columnar diamond single crystal 10 by dry etching using the formed ceramic mask. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a method and system for manufacturing a field emission display, in which a regularly arranged sharp emitter is manufactured with high precision and a high level of productivity without need of complicated manufacturing steps and complicated optical systems. SOLUTION: The method and system comprises a first step for forming a conductive film 16 for forming a cathode electrode on a glass substrate 15 as a base plate, a second step for applying a positive resist 17 as a photosensitive material on the conductive film 16, a third step for exposing the resist to form an opening 20 corresponding to the shape of the emitter 22 by applying the light from a light source as a parallel light having a homogeneous light intensity distribution into a micro lens array 18 and converging the applied light into the positive resist 17 with the micro lens array 18, and a fourth step for forming an emitter 22 in each opening 20.
