Semiconductor manufacturing depends heavily on the ability of machine-vision systems to correctly locate, identify, and align wafers and circuits for testing. Inaccuracy in any of these activities can ...

Researchers have invented a new way to align 3D semiconductor chips by shining a laser through concentric metalenses patterned on the chips to produce a hologram. Their work can help to lower the cost ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Canon U.S.A., Inc., a leader in digital imaging, has announced its entry into the semiconductor back-end manufacturing tool market with the launch of the FPA-5510iV ...

[Left] Semiconductor layers are stacked using concentric metalenses as alignment marks. [Right] Light shines through these marks to project a hologram. The alignment or misalignment of the lenses ...
