Abstract
Damage to and short circuiting of bond fingers on a substrate due to die-attach resin bleed is prevented, thereby increasing yield and improving reliability. Embodiments include forming a trough in a solder mask on a substrate between the bond fingers and semiconductor chip to prevent the die-attach resin from reaching the bond fingers.
