Lower semiconductor package thickness and less weight are among the significant benefits of using ultra-thin die. The methodology used today to assemble circuits with ultra-thin die is time and labor-intensive as well as costly. A high-volume-compatible IC structure for a microelectronic device enabling the attachment of thin die to substrates is proposed that addresses the aforementioned issues.
