Abstract:
A method includes thinning a back-side of a substrate to expose a portion of a first via that is formed in the substrate. The method also includes forming a first diode at the back-side of the substrate. The first diode is coupled to the first via.
Abstract:
Some implementations provide an interposer that includes a substrate, a via in the substrate, and an oxidation layer. The via includes a metal material. The oxidation layer is between the via and the substrate. In some implementations, the substrate is a silicon substrate. In some implementations, the oxidation layer is a thermal oxide formed by exposing the substrate to heat. In some implementations, the oxidation layer is configured to provide electrical insulation between the via and the substrate. In some implementations, the interposer also includes an insulation layer. In some implementations, the insulation layer is a polymer layer. In some implementations, the interposer also includes at least one interconnect on the surface of the interposer. The at least one interconnect is positioned on the surface of the interposer such that the oxidation layer is between the interconnect and the substrate.
Abstract:
A stacked integrated circuit (IC) may be manufactured with a second tier wafer bonded to a double-sided first tier wafer. The double-sided first tier wafer includes back-end-of-line (BEOL) layers on a front and a back side of the wafer. Extended contacts within the first tier wafer connect the front side and the back side BEOL layers. The extended contact extends through a junction of the first tier wafer. The second tier wafer couples to the front side of the first tier wafer through the extended contacts. Additional contacts couple devices within the first tier wafer to the front side BEOL layers. When double-sided wafers are used in stacked ICs, the height of the stacked ICs may be reduced. The stacked ICs may include wafers of identical functions or wafers of different functions.

Abstract:
A photovoltaic (PV) substrate includes a grooved die-facing surface to form a channel for a bypass diode. The die-facing surface supports a screen-printed metal interconnect layer to form a first terminal for the bypass diode.

Abstract:
Some implementations provide an integrated device that includes a first substrate, a first die coupled to the first substrate, a second die coupled to the first die, and a second substrate coupled to the second die. The second substrate is configured to provide an electrical path for a signal to the second die. The integrated device further includes a molding surrounding the first die and the second die, and several through mold vias (TMVs) coupled to the second substrate. The TMVs are configured to provide an electrical path for the signal to the second die through the second substrate. In some implementations, the second substrate includes a signal distribution structure configured to provide the electrical path for the signal to the second die. In some implementations, the first substrate and the second substrate are part of a signal distribution network that provides signal to the second die.
