Patent number: 6802445Abstract: A new method is provided for the creation of high-accuracy and low-accuracy openings overlying points of electrical access over the surface of a semiconductor device supporting substrate. Openings are first created for access to the substrate followed by copper plating and then patterning of the plated layer of copper, creating the interconnect metal over the surface of the substrate. A first solder mask is coated over the surface of the substrate, this first solder mask must be provided with a first array of low-accuracy openings for electrical access there-through for the placement of contact balls. The first openings can be created using conventional film artwork since low accuracy is required for the contact ball openings, resulting in a low-cost process for the creation of the first openings. A second solder mask is next coated over the surface of the first solder mask.Type: GrantFiled: October 24, 2002Date of Patent: October 12, 2004Assignee: St Assembly Test Services Pte.
