Abstract
A semiconductor device manufacturing apparatus includes a pre-alignment section having a pre-alignment camera which is adapted to recognize marks formed on a multi-arrayed substrate, a dicing section which dices the substrate with a cutting blade in accordance with information resulting from image recognition of the marks by the pre-alignment section, and an xy table which carries the substrate. The pre-alignment section recognizes in advance all marks on the substrate based on image recognition thereby to determine the dicing positions, and the dicing section merely recognizes a few points of the substrate with an alignment camera. Consequently, pre-alignment and dicing can take place concurrently, and the throughput of the dicing process can be improved.
