摘要:
An innovative method of manufacturing polishing pads using photo-curing polymers (14) and photolithography. The photolithography enables the creation of useful surface patterns not possible with conventional machining techniques and enables the use of pad materials otherwise too soft to pattern by conventional machining techniques.
