Abstract
This paper presents a circuit-level design and analysis of high-data-rate 3D serial vertical links which exploit the high bandwidth provided by TSV technology. As most of the existing TSVs consume a large amount of die area, the serial configuration can save significant silicon real estate. The performance and jitter characteristic of the proposed 3D link has been accessed for different TSV technologies running worst-case simulations of RC-extracted layouts in 40 nm CMOS-technology. Results show that for a 2-layers system with an aggregate bandwidth of 80 Gbps, an 8-bit data serialization over View the MathML source10μm TSVs consumes just 0.15 pJ/bit including the clock distribution network.

Three-dimensional integrated circuit
A three-dimensional integrated circuit (3D IC) is a MOS (metal-oxide semiconductor) integrated circuit (IC) manufactured by stacking as many as 16 or more ICs and interconnecting them vertically using, for instance, through-silicon vias (TSVs) or Cu-Cu connections, so that they behave as a single device to achieve performance improvements at reduced power and smaller footprint than conventional two dimensional processes. The 3D IC is one of several 3D integration schemes that exploit the z-direction to achieve electrical performance benefits in microelectronics and nanoelectronics.
Integrated circuit
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of miniaturized transistors and other electronic components are integrated together on the chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count.
Serial communication
In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels. Serial communication is used for all long-haul communication and most computer networks, where the cost of cable and synchronization difficulties make parallel communication impractical.
