Abstract:
A method for packaging an integrated circuit. A barrier metal pattern is disposed on a baseplate. A conductive layer is disposed on the barrier metal pattern. A photoresist having a pattern is applied to the conductive layer. A via is then disposed on the conductive layer. An integrated circuit is coupled to the via and encapsulated. Then, at least a part of the baseplate is removed. An integrated circuit package is produced by the method.
