    Abstract: Methods for forming semiconductor structures are provided. The method for forming a semiconductor structure includes forming a metal pad over a first substrate and forming a resist layer having an opening over the metal layer. The method for forming a semiconductor structure further includes forming a conductive pillar and a solder layer over the conductive pillar in the opening of the resist layer and removing the resist layer. The method for forming a semiconductor structure further includes removing a portion of the conductive pillar so that the conductive pillar has an angled sidewall.
