Through silicon vias (TSV)
Through silicon vias (TSV) is a key enabling element the provides short vertical interconnects in die stacks to improve electrical performance, power consumption, and form factor for 3D integrated devices. The mismatch of thermal expansion coefficients between the copper via and the silicon wafer can induce significant thermal stresses to degrade the...

Fiber Optic Infrared Absorption Gas Sensors with Metal-Organic Framework Materials
Technology Description The fiber-optic chemical sensing platform couples light guides with a metal-organic framework (MOF) and plasmonic nanomaterial sensing components to provide increased near-infared (NIR) detection sensitivity. The MOF thin films rapidly absorb and sense gases by leveraging a network of plasmonic nanocrystals that act at the NIR...
