A power module includes a number of sub-modules connected via removable jumpers. The removable jumpers allow the connections between one or more power semiconductor die in the sub-modules to be reconfigured, such that when the removable jumpers are provided, the power module has a first function and when the removable jumpers are removed, the power module has a second function. The removable jumpers may also allow for independent testing of the sub-modules. The power module may also include a multi-layer printed circuit board (PCB), which is used to connect one or more contacts of the power semiconductor die. The multi-layer PCB reduces stray inductance between the contacts and therefore improves the performance of the power module.

An electronic package may be fabricated by forming a first layer of insulating material on a first substrate such that the first layer covers a contact pad; forming an opening through the first layer to expose the contact pad; forming an un-patterned second layer on the first layer, the second layer including an adhesive having a viscosity less than that of the first layer, wherein a region of the second layer obstructs the contact pad; removing the region to re-expose the contact pad; aligning a second substrate with the first substrate such that a via of the second substrate is aligned with the opening; bonding the first substrate and the second substrate together at the second layer; and forming an interconnect in contact with the contact pad by depositing a conductive material through the via and the opening.
