An electronic device comprises an integrated circuit (IC) die. The IC die includes a first bonding pad surface and a first backside surface opposite the first bonding pad surface; a first active device layer arranged between the first bonding pad surface and the first backside surface; and at least one stacked through silicon via (TSV) disposed between the first backside surface and the first bonding pad surface, wherein the at least one stacked TSV includes a first buried silicon via (BSV) portion having a first width and a second BSV portion having a second width smaller than the first width, and wherein the first BSV portion extends to the first backside surface and the second BSV portion extends to the first active device layer.

Micro through-silicon via for transistor density scaling

Disclosed embodiments include a multi-chip package that includes a stacked through-silicon via in a first semiconductive device, and the first semiconductive device is face-to-face coupled to a second semiconductive device by the stacked through-silicon via. The stacked through-silicon via includes a first portion that contacts a second portion, and the first portion emerges from an active semiconductive region of the first semiconductive device adjacent a keep-out region.

Stacked through-silicon vias for multi-device packages

A semiconductor device and associated methods are disclosed. In one example, dies are interconnected through a bridge in a substrate. A reference voltage stack extends over at least a portion of the interconnect bridge, and a passive component is coupled to the reference voltage stack. In one example, the passive component helps to reduce interference in the power supply to components in the semiconductor device, such as the dies and the interconnect bridge.

Power delivery for embedded interconnect bridge devices and methods

Devices and methods related to an integrated circuit device are provided. The integrated circuit device includes a mother die and a daughter die, in which the daughter die embedded is in a substrate of the integrated circuit device. Micro bumps of the mother die and the daughter die interface together to form a direct down connection between the mother die and the daughter die.

Interconnection of an embedded die

The present disclosure relates to an innovative method of assigning signals to general-purpose input/output pads of an integrated circuit chip. An inductance matrix for the input/output pads is obtained. A candidate assignment is made of a differential signal to a pair of the input/output pads, and a differential mutual inductance is determined for each open pad location in relation to the pair of input/output pads. Single-ended signals are assigned to open pad locations having the lowest differential mutual inductances. The jitter contribution due to each assigned single-ended signal is computed, and a total jitter is updated. In a first embodiment, said assigning, computing and updating steps are repeated until the total jitter exceeds a total jitter budget. In a second embodiment, said assigning, computing and updating steps are repeated until a number of assigned single-ended signals is equal to a target number. Other embodiments and features are also disclosed.
