Abstract

Embodiments herein describe techniques for an IC package including a supporting layer having a first zone and a second zone. An electronic component is placed above the first zone of the supporting layer. An underfill material is formed above the first zone of the supporting layer, around or below the electronic component to support the electronic component. The second zone of the supporting layer includes a base area and multiple micro-pillars above the base area, where any two micro-pillars of the multiple micro-pillars are separated by a gap in between. The second zone has a hydrophobic surface including surfaces of the multiple micro-pillars and surfaces of the base area. The second zone is a keep out zone to prevent the underfill material from entering the second zone. Other embodiments may be described and/or claimed.
