Three-dimensional Heterogeneous Integration Overview

Principles

Definition

Three-dimensional heterogeneous integration is three-dimensional heterogeneous integration is an advanced research concept and technological approach focused on the vertical integration and interconnection of diverse microfabricated components, such as integrated circuits, MEMS, RF, and photonic devices, fabricated using potentially dissimilar materials, processes, or technology nodes. This field investigates methods to combine these heterogeneous elements within a three-dimensional architecture to achieve significantly enhanced functionality, increased integration density, and superior system performance, thereby addressing limitations inherent in traditional two-dimensional and homogeneous integration techniques.

Foundational 3D Integration era

E. Sprogis [1] is associated with Essex Westford School District [3] during the Foundational 3D Integration era. His key contributions in this era, as evidenced by Three-dimensional silicon integration [5], 3D chip-stacking technology with through-silicon vias and low-volume lead-free interconnections [6], and 3D chip stacking with C4 technology [7], helped establish manufacturable wafer-level 3D integration by detailing vertical interconnect fabrics and stacking topologies, which addressed yield risk and enabled scalable heterogeneous assembly. Katsuyuki Sakuma [2] is affiliated with Waseda University [4] during this era. Sakuma's contributions, as reflected in Three-dimensional silicon integration [5], 3D chip-stacking technology with through-silicon vias and low-volume lead-free interconnections [6], and 3D chip stacking with C4 technology [7], helped establish foundational methods for bonds, alignments, and thermal-aware design rules that underpinned manufacturability of 3D stacks in this era.

Chiplet-Driven 3D Integration era

H.‐S. Philip Wong [1] is associated with the Massachusetts Institute of Technology [3] and Stanford University [4] in this era. His key contribution, articulated in the 2017 paper 'Three-dimensional integration of nanotechnologies for computing and data storage on a single chip' [5], was to advance three-dimensional integration concepts by integrating nanoscale technologies for computing and data storage on a single chip, enabling higher density and interconnect bandwidth crucial for chiplet-driven 3D integration. Subhasish Mitra [2] is associated with the Massachusetts Institute of Technology [3] and Stanford University [4] in this era. His key contributions, described in the same 2017 paper [5], helped articulate a framework for 3D integration of nanotechnologies for computing and data storage on a single chip, laying a foundation for standardized interconnects and wafer-to-wafer bonding essential to chiplet-driven 3D integration.
