Hi, you can use the positive photoresist AZ4562 (or the SPR220), his prebake temperature is around 105°C (115) and it is very strong in RIE process, best, Alaa limengyue26 a écrit : > dear all, > > We are using your Microchem's product - PMMA, the Positive EB resist. But during our microfabrication process, the tempature is not allowed to be higher than 100°C. But the prebaking tempature of PMMA is always 180°C, or ranging from 140°C to 200°C in the data sheet. > > The second problem of PMMA is it can not bear severe RIE(reactive ion ething). > > Do you have some suggestion about some resist which property is similar to PMMA but can be prebaked at lower tempature, 120°C at most, and of course not higher than 100°C is better. At the same time, it also can have a better performance when RIEed. > > Thank you ! > > limengyue -- Alaa el dine ALLOUCH Doctorant au LAAS-CNRS-Groupe N2IS 7 Av colonel Roche, 31077 Toulouse Tél : 05 61 33 78 71
