摘要:
A method of enabling selective area plating on a substrate includes forming a first electrically conductive layer (310) over substantially all of the substrate, covering sections of the first electrically conductive layer with a mask (410) such that the first electrically conductive layer has a masked portion and an unmasked portion, forming a second electrically conductive layer (710, 1210), the second electrically conductive layer forming only over the unmasked portion of the first electrically conductive layer, and removing the mask and the masked portion of the first electrically conductive layer. In an embodiment, the mask covering sections of the first electrically conductive layer is a non-electrically conductive substance (1010) applied with a stamp (1020). In an embodiment, the mask is a black oxide layer.

A method of removing unwanted material from a substrate includes providing a system (600) having an etchant solution (610) with an electrode (620) therein and a current supply (630) connected to the electrode, placing the substrate in the solution and connecting it to the current supply, providing an electric current to the electrode, and altering a polarity of the electric current such that the substrate experiences an anodic polarity for a first time period and a cathodic polarity for a shorter time period. An alternative method includes providing a solution delivery system (1100) having a second etchant solution (1110) with an eductor jet (1140) therein and a recirculation pump connected to the eductor jet, placing the substrate in the second solution, and using the eductor jet to spray the substrate with the second solution. If desired, both methods may be used.

A first acousto-optic deflector receives a laser beam. The first acousto-optic deflector diffracts the received laser beam along a first axis. A second acousto-optic deflector receives the diffracted laser beam. The second acousto-optic deflector diffracts the received diffracted laser beam along a second axis.

摘要:
A method includes generating a laser beam and applying the beam to a substrate to form a via in the substrate. The laser beam has an intensity profile taken at a cross-section transverse to the direction of propagation of the beam. The intensity profile has a first substantially uniform level across an interior region of the cross-section and a second substantially uniform level across an exterior region of the cross-section. The second intensity level is greater than the first intensity level.

Embodiments of the present disclosure are directed towards package assembly configurations for multiple dies and associated techniques. In one embodiment, a package assembly includes a package substrate having a first side and a second side disposed opposite to the first side, a first die mounted on the first side and electrically coupled with the package substrate by one or more first die-level interconnects, a second die mounted on the second side and electrically coupled with the package substrate by one or more second die-level interconnects and package-level interconnect structures disposed on the first side of the package substrate and configured to route electrical signals between the first die and an electrical device external to the package substrate and between the second die and the external device. Other embodiments may be described and/or claimed.
