METHODS FOR REGISTRATION OF CIRCUIT DIES AND ELECTRICAL INTERCONNECTS
A method includes placing an electronic device on a pliable mating surface on a major surface of a mold such that at least one contact pad on the electronic device presses against the pliable mating surface. The pliable mating surface is on a microstructure in an arrangement of microstructures on the major surface of the mold. A liquid encapsulant material is applied over the electronic device and the major surface of the mold, and then hardened to form a carrier for the electronic device. The mold and the carrier are separated such that the microstructures on the mold form a corresponding arrangement of microchannels in the carrier, and at least one contact pad on the electronic device is exposed in a microchannel in the arrangement of microchannels. A conductive particle-containing liquid is deposited in the microchannel, which directly contacts the contact pad exposed in the microchannel.
Solderable contact regions
A contact region for a semiconductor substrate is disclosed. Embodiments can include forming a seed metal layer having an exposed solder pad region on the semiconductor substrate and forming a first metal layer on the seed metal layer. In an embodiment, a solderable material, such as silver, can be formed on the exposed solder pad region prior to forming the first metal layer. Embodiments can include forming a solderable material on the exposed solder pad region after forming the first metal layer. Embodiments can also include forming a plating contact region on the seed metal layer, where the plating contact region allows for electrical conduction during a plating process.
