SpletThis paper reports on wafer-to-wafer adhesive bonding using SINR polymer materials. Substrate coating process as well as wafer bonding process parameters optimization was studied. Wafer bonds exceeding the yield strength of the SINR polymer were accomplished on 150 mm Si wafers. Features of as low as 15 μm were successfully resolved and bonded. Splet10. nov. 2024 · Spin-coating is the most common method used when coating a substrate with photoresist. It is a method that presents a high potential for throughput and homogeneity. The principle of spin-coating is that typically a few millilitres of photoresist are dispensed on a substrate which is spinning at several 1000 rpm (typically 4000 rpm). …
