Abstract: Technologies for ribbon field-effect transistors with variable fin numbers are disclosed. In an illustrative embodiment, a stack of semiconductor fins is formed, with each semiconductor fin having a source region, a channel region, and a drain region. Some or all of the channel regions can be selectively removed, allowing for the drive and/or leakage current to be tuned. In some embodiments, one or more of the semiconductor fins near the top of the stack can be removed. In other embodiments, one or more of the semiconductor fins at or closer to the bottom of the stack can be removed.

Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques related to glass layers within a package that include one or more high aspect ratio TGV that are filled with conductive material. The TGV extends from a first side of the glass layer to a second side of the glass layer opposite the first side and are filled with conductive material to provide a high-quality electrical connection between the first side of the glass layer and the second side of the glass layer, where a portion of the wall of the TGV includes titanium. Other embodiments may be described and/or claimed.

Abstract: Glass substrates having transverse capacitors for use with semiconductor packages and related methods are disclosed. An example semiconductor package includes a glass substrate having a through glass via between a first surface and a second surface opposite the first surface. A transverse capacitor is located in the through glass via. The transverse capacitor includes a dielectric material positioned in a first portion of the through glass via, a first barrier/seed layer positioned in a second portion of the through glass via, and a first conductive material positioned in a third portion of the through glass via.

Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques directed to embedding capacitors in through glass vias within a glass core of a substrate. In embodiments, the through glass vias may extend entirely from a first side of the glass core to a second side of the glass core opposite the first side. Layers of electrically conductive material and dielectric material may then be deposited within the through glass via to form a capacitor. the capacitor may then be electrically coupled with electrical routings on buildup layers on either side of the glass core. Other embodiments may be described and/or claimed.

Abstract: An electronic device comprises an electronic package with a glass core. The glass core includes a first surface and a second surface opposite the first surface, at least one through-glass via (TGV) extending through the glass core from the first surface to the second surface, and including an electrically conductive material, and wherein the at least one TGV includes a first portion having a first width and a second portion having a second width different from the first width.
