Project Description

The project addresses interlayer cooling of 3D computer  chips, including water cooling, two-phase refrigerant cooling, development and perfection  of new micro-fabrication techniques  for TSVs and their connections, bonding  of stacked layers together, dynamic thermal modeling of 3D chips, and extensive experimental testing of2D and 3D cooling solutions and new thermal models.
