<p>PROBLEM TO BE SOLVED: To provide a field-effect electron emitting element having a diamond thin film chip that utilizes a diamond thin film having a low work function due to negative electron affinity and allowing its yield to be improved even in manufacturing large size elements. SOLUTION: This field-effect electron emitting element includes a back substrate 11, a striped negative electrode 12 of a predetermined thickness formed on the said back substrate, a micro-chip supporting member 12' of a specicied material having a predetermined height that is formed on the said negative electrode, a micro chip 12" of a material having a work function not more than a specified value that is formed into a flat plate of a predetermined thickness, and a hole surrounding the micro-chip supporting member 12. The element is also provided with an insulation layer 13 that is formed to situate at a position lower than the micro chip 12" by a predetermined height, an opening that is formed on the insulation layer 13 a specified distance away from the micro- chip supporting member 12', and a gate 14 that is formed to situate at a position lower than the micro chip 12" by another predetermined height.</p> |
