The T4X sub-micron micro-roughening treatment significantly increases surface area without affecting roughness, which is especially helpful for increasing adhesion strength. With high particle adhesion, there is no worry of particles falling off and contaminating lines. The Rzjis value after roughening is maintained at 1.0 µm and transparency of the film after being etched is also good.
