Hi Andrea,
Try AZ9260, it performs better than AZ4562 and 4620 for a layer
thicker than 10um. I got thickness from 5um to 30um. But the
uniformity is not perfect when you are dealing with a very thick
layer. And the pattern would be slightly larger than your mask since
you have to over expose your wafer.
Good luck.
