Abstract:
A wet processing system comprising:a processing bath filled with chemicals;a wafer carrier for carrying wafers each having a first diameter; anda transport jig for conveying said wafer carrier by holding an upper end portion of said wafer carrier;said wafer carrier comprising:at least three bars each being formed with a plurality of grooves for receiving edge portions of the wafers;a pair of support plates supporting opposite ends of said at least three bars arranged complimentarily to a contour of the wafers such that said wafers are each held in an upright position with a lower portion thereof received in said grooves at least three points thereof;a pair of lugs protruding from an outer surface of an upper portion of each of said pair of support plates, and for retaining pawls of arms constituting said transport jig, so that said transport jig is engageable with said pair of support plates at opposite ends of said at least three bars andwherein the wafers are held in parallel with said pair of support plates. and a width of each of said support plates is less than a first diameter of each of said wafers to be accommodated in said wafer carrier, andwherein the entire upper end portion of said pair of support plates is positioned below a center of said wafers.
