Patent ID: 6845779

Claim:
A microelectronic substrate handling device for immersion processing and for supporting and transfer of at least one generally planar microelectronic substrate, the handling device comprising a movable support member and first and second support structures extending from a surface of the movable support member and operatively spaced from each other to support at least one microelectronic substrate between the first and second support structures, the second support structure comprising a series of teeth defining a series of notches extending along a length of the second support structure and the first support structure comprising: a series of upper teeth extending along a length of the first support structure and defining a series of upper notches opening toward the series of notches of the second support structure for receiving an edge of a microelectronic substrate when supported by the first and second support structures, the upper teeth having substrate engaging surfaces angled with respect to the direction of extension of the upper teeth for engaging and urging substrates in a direction of the series of upper teeth; and a series of lower teeth extending along a length of the first support structure and defining a series of lower notches opening toward the second support structure for receiving an edge of a microelectronic substrate when supported by the first and second support structures, wherein the upper and lower notches of the first support structure are offset from each other by a first predetermined offset distance so that an edge of a generally planar microelectronic substrate can fit similarly within notches of the second support structure and the lower teeth of the first support structure but differently within the upper notches of the first support structure when supported between the first and second support structures.
