Keyway alignment substrates |
摘要 |
The vacuum hold down alignment substrate is formed as an array of precisely aligned alignment substrate subunits. Each subunit is formed with an alignment pattern formed in a photo-patternable or electroformable material. When the plurality of alignment substrate subunits are formed into an array to produce the alignment substrate, the alignment patterns are aligned to receive corresponding patterns in discrete subunit devices which are aligned into an array on the alignment substrate. |
