This work demonstrates 50 µm (2.0 mil) thin SCHOTT glass AF32eco as a RF substrate. Superior electrical performance and miniaturized component or package size in both vertical and lateral dimensions compared to traditional components and two-dimensional (2D) packages are shown to be feasible with the 3D fabrication approach with such thin glass. Vias with a diameter of 50µm are made at SCHOTT using laser structuring. Either sides of the glass substrates are coated with a thin layer of a polymer… 
Glass in wafer- and panel-level packaging: Changes, challenges, hurdles and barriers
In principle there exists a large variety of compositions for oxide glasses. Also a variety of hot forming processes is present for glasses, which allows near end shape processing. In particular thin
Attenuation of high Frequency Signals in Structured Metallization on Glass: Comparing Different Metallization Techniques with 24 GHz, 77 GHz and 100 GHz Structures
A number of glass substrates made from the SCHOTT glass AF32_eco in a thickness of 0.1mm are metallized with different processes. On the metallized glass substrates, microstrip lines as well as ring


High-performance electroplated solenoid-type integrated inductor (SI/sup 2/) for RF applications using simple 3D surface micromachining technology
Electroplated solenoid-type integrated inductors (SI/sup 2/s) have been demonstrated to have high performance and small area occupation for GHz applications, using a new, simple, and highly adaptable
Direct copper metallization on glass technology + x-substrate
