General Information

This special photoresist is intended forlift-off techniques which call for a negative side wall profile. The reversal bakemoderately cross-links the exposed resist making the developed structuresthermally stable up to approx. 130°C. Due to the comparably low resist filmthickness, the process parameter window for an undercut is rather small thusrequiring some optimizations in the exposure dose and the reversal bake parameters. Therefore, if the resolution required is not in the sub-µm range, a thickerresist such as the TI 35ESx (next section), or the AZ® nLOF 2000 negative resistsmight be a good alternative.


AZ® 726 MIF or AZ® 351B 1 : 4 recommended;
AZ® 326 MIF or AZ® 400K 1 : 4 possible
