Abstract: Embodiments described herein may be related to apparatuses, processes, and techniques related to hydrophobic features to block or slow the spread of epoxy. These hydrophobic features are placed either on a die surface or on a substrate surface to control epoxy spread between the die in the substrate to prevent formation of fillets. Packages with these hydrophobic features may include a substrate, a die with a first side and a second side opposite the first side, the second side of the die physically coupled with a surface of the substrate, and a hydrophobic feature coupled with the second side of the die or the surface of the substrate to reduce a flow of epoxy on the substrate or die. In embodiments, these hydrophobic features may include a chemical barrier or a laser ablated area on the substrate or die. Other embodiments may be described and/or claimed.

Abstract: In non-limiting examples of the present disclosure, systems, methods and devices for surfacing content related to electronic calendar events are presented. An electronic calendar event library may be maintained. One or more calendar events that meet threshold time criteria in relation to a current time may be identified. One or more rules may be applied to the identified events to determine whether contextual information and/or actions should be surfaced in relation to those events. In some examples, an event priority score may be calculated for each of the identified events. Contextual information and/or actions associated with events with event priority scores that exceed a threshold value may be surfaced. The contextual information and/or actions may be prioritized based on the event priority scores.
