Production NIL Equipment
Fully Automated UV Nanoimprint System
Dyad® 200
Developed by SCIVAX × Tazmo Co., Ltd.

A production UV imprint system jointly designed and developed with Tazmo Co., Ltd., a semiconductor manufacturing equipment manufacturer, integrating SCIVAX’s diverse imprint mechanisms into a single platform. The Hard-to-Hard imprint method, which uses a rigid substrate as the replica stamp base material, enables high-precision, high-yield mass production.

Dyad® 200 Fully Automated UV Nanoimprint System
Challenges Solved by the Hard-to-Hard Method

Improved Uniformity for
AR Glass Waveguides

Compared with flex-substrate replicas, imprint distortion across the wafer is significantly reduced. Improved uniformity and image quality have been demonstrated in waveguide molding for AR glasses.

Overlay Alignment
≤±1μm

Achieves ≤±1μm with an optional alignment mechanism at mass-production level. Supports device manufacturing that requires precise pattern alignment.

Improved Release Performance for
High-Aspect-Ratio Structures

Mitigates replica damage that can occur during demolding of high-aspect-ratio structures such as pillar and hole shapes. Improves yield and productivity simultaneously.
