| 摘要 |
A semiconductor device fabricated on a multiple substrate with a first structure including a first semiconductor substrate with at least one first bonding pad and at least one alignment key formed thereon, and a second structure including a second semiconductor substrate with at least one second bonding pad and at least one alignment aperture passing through the second semiconductor substrate. By irradiating a UV beam through the alignment aperture and detecting reflection off the alignment key, the first and second semiconductor substrates are aligned.
