(2.) The modified solvent system improved penetration on the high Tg material, enabling the permanganate to increase the degree of resin removal and sufficiently roughen the resin to enhance subsequent adhesion of metalization layer.
Physically, during the initial portion of the bias pulse, the heat generated at the junction travels through the silicon material and the gold metalization layer only.
