| Research Abstract |
At first, we developed an apparatus for the electron beam assisted chemical machining (EBACE). Then, machining characteristics of diamond by the EBACE was investigated in order to apply the EBACE to finishing ultra-precision diamond tools and to delineating fine patterns into electronic diamond devices. Last year, we developed the machining stage for making the three dimensional profile on the top of a diamond probe. From the experiments, following results are obtained.
(1) Hole, line and rectangular patterns were successfully fabricated by EBACE with hydrogen and oxygen gases.
(2) In the case of fabrication of the rectangular pattern with hydrogen gas, the etched depths are proportional to the etching time also the etched depth increases with a decrease of the heam scan speed and acceleration voltage of beam.
(3) From Raman spectroscopy, it is conclude that the single crystal diamond chip machined with EBACE has no damage.
(4) The three dimensional protrusion on the top of a diamond probe was successfully fabricated utilizing the developed machining stage. Moreover, fine patterns were delineated into electronic diamond devices.
