Abstract
PURPOSE: To achieve the improvement in the frequency characteristics, transient characteristics, etc. of the cartidge by forming the base surface of the cantilever with a high specific modulus material layer by a plasma chemical vapor deposition method thereby enhancing its strength and rigidity.
CONSTITUTION: An Al wire of, e.g., 0.3mm is put in a high frequency heating furnace, into which mixed gases of boron trichloride and hydrogen are introduced and high frequency electric fields are applied by operating a plasma generating high frequency power source under heating and reduced pressure to turn the mixed gases to plasma, thus letting boron be formed on the Al wire. This is cut to a suitable length and a diamond chip which becomes sytlus tip is bonded and fixed to form the solid cantilever. Or after it is cut to a suitable length, it is subjected to chemical etching treatment in etching solution such as of hydrogen chloride or other to remove the base, whereby the pipe form cantilever of the boron alone is formed
