A microelectronic package may include a first microelectronic unit including a semiconductor chip having first chip contacts, an encapsulant contacting an edge of the semiconductor chip, and first unit contacts exposed at a surface of the encapsulant and electrically connected with the first chip contacts. The package may include a second microelectronic unit including a semiconductor chip having second chip contacts at a surface thereof, and an encapsulant contacting an edge of the chip of the second unit and having a surface extending away from the edge.

摘要:
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.
摘要:
The present invention relates to a method for electrically connecting wafers, which physically bonds two wafers through an oxide-to-oxide bonding method and then electrically connects the two wafers through a butting contact structure. The wafers are physically bonded to each other through a relatively simple method, and then electrically connected to through TSVs or butting contact holes. Therefore, since the fabrication process may be simplified, a process error may be reduced, and the product yield may be improved.
