Web1 jul. 2016 · We have also verified the full ‘lab-to-fab’ (i.e., from laboratory to fabrication) process of our metal-oxide photoresist approach. 8, 9 In particular, we integrated the metal-oxide resist into our 7nm back-end process module, a block mask layer for metal patterning with pillar dimensions down to 21nm. We have thus demonstrated (see Figure 4) that our … WebIntroduction As lithography moves deeper into the low-k1 regime, co-optimization of layout, mask, and lithography is critical to deliver a production-worthy patterning solution. The goal of co-optimization is to create a design, along with its corresponding resolution enhancement technology (RET) solution, that is relatively insensitive to manufacturing process variations.
