3D-Stacked CMOS Sparks Imaging’s Innovation Era
CMOS manufacturing has undergone a significant transformation in the last 12 months. The manufacturing processes that even seasoned developers regarded as fundamentally experimental 20, or even 10, years ago have come within reach of enabling an entirely new set of commercial applications. These breakthroughs, such as 3D stacking, are emerging in addition to the applications that industry innovators have already demonstrated owing to advancements in CMOS manufacturing processes.

A Quantum Leap for Sensitive Gas Analysis
Far above an oil pipeline, a drone bobs and weaves. The drone, dispatched by Denver, Colorado-based Project Canary, is collecting high-resolution imaging data of the site, while also scanning for any indications that the pipeline is leaking methane. Methane is a potent greenhouse gas, and Project Canary cofounder and co-CEO Will Foiles saw a valuable opportunity to act against climate change by giving oil and gas facilities the ability to quickly detect and prevent its release into the atmosphere.

Traceable Standards Could Speed Development of Quantum Technologies
Researchers at the National Institute of Standards and Technology and the University of Maryland have developed standards and calibrations for the optical microscopes used to guide the centering of quantum dots within photonic chips. The method enables a precision down to 10-20 nm across the entire image from an optical microscope, allowing the correction of many individual quantum dots.

Optical Filters: Application and Design Considerations
Tue, Apr 23, 2024 1:00 PM - 2:00 PM EDT
Optical filters can discretely transmit or reject specific wavelengths or ranges of wavelengths of light. Utilizing this capability in photonics-based instruments creates the need for a better understanding of optical filter design considerations and how specifications influence performance and cost. Craig Hanson of MKS/Newport discusses the fundamental principles of optical coatings and filter types and explains the significance of filter parameters and the benefits of design review. He also explores accessory options and subsystem integration. Next Hanson unveils MKS’s unique manufacturing processes and capabilities for custom optical filters from prototype to high-volume production. Finally, this presentation concludes with an open Q&A, for which Hanson is joined by Mark Roberts, principal thin-film engineer at Newport. Presented by MKS Newport.
