Abstract
Guard ring technology is disclosed. In one example, an electronic component guard ring can include a barrier having a first barrier portion and a second barrier portion oriented end to end to block ion diffusion and crack propagation in an electronic component. The guard ring can also include an opening in the barrier between the first and second barrier portions extending between a first side and a second side of the barrier. Associated systems and methods are also disclosed.

An electronic component guard ring, comprising:
- a barrier comprising a contiguous material extending through layers of conductive material and layers of insulative material, the barrier having a first portion and a second barrier portion oriented end to end to block ion diffusion and crack propagation in an electronic component;
- and
- an opening in the barrier between the first and second barrier portions extending between a first side and a second side of the barrier, wherein the opening comprises bridges of semiconductor material extending between conductive material on the first side and conductive material on the second side of the barrier.
