The Effects of Etchant on via Hole Taper Angle and Selectivity in Selective Laser Etching

open access: yesMicromachines
This research focuses on the manufacturing of a glass interposer that has gone through glass via (TGV) connection holes. Glass has unique properties that make it suitable for 3D integrated circuit (IC) interposers, which include low permittivity, high ...

The influence of sputter-deposited indium tin oxide thin films on the strength of ultra-thin glass

open access: yesOpen Ceramics
Ultra-thin glass with a thickness of 100µm or below is an attractive substrate for sputter deposition of thin films. However, research has shown that the deposition of functional coatings is often correlated with a significant strength reduction of the ...

Theory of electron beam moire

open access: yesJournal of Research of the National Institute of Standards and Technology, 1996
When a specimen surface carrying a high-frequency line grating is examined under a scanning electron microscope (SEM), moiré fringes are observed at several different magnifications. The fringes are characterized by their spatial frequency, orientation, and contrast.
