Looking Back on a Major Milestone

Ten years ago today — on 21 October 2004 — Tezzaron demonstrated the world’s first working 3D-IC!

The device was a two-layer wafer-stacked chip with tungsten SuperContact™ (vertical interconnect).  It was part of an in-house multi-project wafer stack containing six different 3D designs, all of which were first-pass functional.  The first … [Read More]

Fermilab 3D Sensor Breakthrough

A new 3D sensor prototype with extraordinary capabilities was recently revealed by Grzegorz Deptuch of Fermilab.  The three-layer sensor, named VIPIC, is designed for particle detection in large-scale particle physics and x-ray imaging experiments.  It exhibits higher and more uniform gain, higher signal amplitude, lower input capacitance, and much lower … [Read More]

COSMOS, DAHI, and mixed-material 3D

A hotly-pursued goal of 3D-IC technology is the integration of circuitry built on different substrates. Phil Garrou reports in his blog, “Insights from the Leading Edge,” that DARPA is leading the way with its COSMOS and DAHI programs. Tezzaron and Novati are participants in these programs.  You can read Phil’s … [Read More]
