Abstract
PURPOSE: To bore minutes holes with hig precision, by arranging a corrodible material in the holding work position and by removing said material with the etching liquid by etching, in case that minutes holes are bored in the material to be worked.
CONSTITUTION: In case that the hole of diameter B 40μm and depth A 0.5mm is bored on the gass, copper wire 2 of diameter 40μm is arranged on jig 1 and is molded by low-melting poing glass 3. Next, the material to be worked including jig 1 is put in solution of ammonia and ammonium persulfate to etch copper wire 2. Thus, by removing copper wire 2 from low-melting point glass 3, the hole is bored in glass of low-melting point 3. After that, glass of low-melting point 3 including jig 1 is cut into a prescribed thickness to complete the holding work of the minute diameter.
