Imprinting machine Film mold

Imprinting machine Film mode

To support imprinting on a warped substrate or depositing defect substrate, a flexible resin mold is used in order to enable imprinting with high accuracy of form and less dispersion of residual resin layer.   
Film mode can be created by the roll-to-roll imprinting machine.

Imprinting machine Alignment function

Imprinting machine Alignment function

Positioning errors can be measured by monitoring each alignment mark of the substrate and the mold.Alignment is adjusted by shifting the substrate or mold on the XYC stage.By monitoring right and left alignment marks, swiveling position can also be aligned with C axis. 
Furthermore, dedicated control software can be used for automatic alignment.

Imprinting machine ST Head

Imprinting machine ST head

In order to imprint fine patterns on a wide area, it is important to ensure uniformity of the pattern on the transcription surface. The ST head (ST stage if installed in the lower part) prevents ununiform contact caused by parallelism difference between the substrate and mold to enable uniform transcription on the surface.To ensure the parallelism between the substrate and the mold, the head to which the mold is mounted has the free-tilting function to adjust its angle when the substrate contacts the mold.

Imprinting machine Molding solution

Imprinting machine Molding solution

Depending on the quality of resin used, three types of molding methods are available: UV imprinting that uses UV curable resin; Thermal imprinting that uses thermosetting or thrmoplastic resin; and room temperature imprinting that pressure curable rasin such as SOG. 
The ST machine is fully customizable according to the resin used.
