Abstract

A semiconductor chip includes a body having a frontside, a backside opposite the frontside, and sidewalls extending between the backside and frontside, at least a portion of each sidewall having a defined surface structure with hydrophobic characteristics to inhibit travel of a bonding material along the sidewalls during attachment of the semiconductor chip to a carrier with the bonding material.
