METHOD OF MANUFACTURING A SUCTION PAD WITH MICRO SUCTION ARRAY STRUCTURE |
摘要 |
PURPOSE: A method for manufacturing an adsorbing pad with a fine adsorbing structure is provided to obtain a three-dimensional fine adsorbing structure using a semiconductor photolithography process and to ensure a vacuum state regardless of dry or wet states of an adsorbing material. CONSTITUTION: A method for manufacturing an adsorbing pad with a fine adsorbing structure comprises the steps of: forming a fine pattern in a first hemisphere shape using a first photolithography process and a thermal reflow process on a silicon substrate (b); manufacturing a mold forming a reverse shape in a fine adsorbing structure by forming the fine pattern of a second sensitizer by a second photolithography process on the silicon substrate (d); forming an adhesive preventing film on the mold; hardening the same by molding mixed solution of a curing agent and a polymer which is a material for the adsorbing pad on the mold (e); and separating the adsorbing pad from the mold (f).
