Nano imprint lithography offers high-throughput alternative for photonic chip manufacturing

By PulseAugur Editorial · [3 sources] ·

Nano imprint lithography (NIL) is being explored as a high-throughput alternative to electron beam lithography for manufacturing photonic integrated circuits (PICs). While e-beam lithography offers precision and flexibility, its low throughput makes it impractical for mass production. NIL, demonstrated by EVG at Semicon Taiwan, uses a mold to stamp patterns onto wafers, potentially achieving similar resolution at much higher speeds. However, challenges remain, including surface cleanliness, precise overlay, mold degradation, and wafer flatness. AI
