Trace Micralign Adoption Across the Industry

# Trace Micralign's Adoption Across the Industry

Chipmakers evaluating Micralign against their existing contact-printing lines weighed the new system's higher throughput, extended mask lifetime, and improved yield against its higher purchase cost.

Those production benefits were large enough that major semiconductor manufacturers began bringing Micralign systems into their fabs through the mid-1970s rather than continuing to invest in contact-printing capacity.

This adoption pattern, driven by concrete yield and cost data rather than novelty, is what turned projection lithography from one company's new product into an industry-wide manufacturing standard.
