Corner Stress Release Structure Design for Increasing Circuit Routing Areas

摘要

An integrated circuit structure includes a semiconductor chip, which further includes a corner and a seal ring dispatched adjacent edges of the semiconductor chip; and a corner stress release (CSR) structure adjacent the corner and physically adjoining the seal ring. The CSR structure includes a portion in a top metallization layer. A circuit component selected from the group consisting essentially of an interconnect structure and an active circuit is directly underlying the CSR structure.
