Title: Method for manufacturing ars system
Inventor: LEE HEON
IPC: B81B3/00
Filed: 2002-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an ARS system capable of curbing damage, solving the problem of heat related restrictions, and improving on the yield. SOLUTION: Using this method, conductive electrodes are bonded to the rotor wafer media side before the wafer thinning process by polishing or by CMP, and the electrodes are protected from polishing or the like. The design allows CMOS circuitry formation to be accomplished in the latter half of the manufacturing process, minimizes the impact of heat treatment, and alleviates heat related restrictions in other treatments. Since the bonding of the rotor wafer and starter wafer is carried out at a later stage, degradation of the bonding between wafers is minimized. These improves on the yield and reduces the manufacturing cost.
