Effect of Applying Ultrasonic Vibration in Hot Embossing and Nanoimprint
Moreover, it turned out that when the contact force was too large in the ultrasonic hot embossing, the overload disturbed the spread of the ultrasonic vibration, and the molding accuracy worsened. Figure 4(e) shows the SEM image of the embossed pattern when the contact force F was set to 4.0 kN, while other parameters being same as in Fig. 4(b) .
