Latest Patents
One of Steven Hartmann's notable patents is titled "Active Metrology Frame and Thermal Frame Temperature Control in Imprint Lithography." This invention involves a thermal frame of an imprinting apparatus that includes a motor and a cooling element. The metrology frame is coupled to the output end of the motor and receives an imprinting mold. Thermal isolation is provided between the motor and the metrology frame, ensuring that temperature variations do not affect the imprinting process. Thermal sensors are strategically placed at various locations on the frames. A digital controller applies a control signal to manage the driving signal of the cooling element, maintaining thermal balance and equilibrium of heat flow between the frames. The innovative feedforward design of this system avoids the low control bandwidth that typically limits the performance of standard feedback designs. Steven holds 1 patent in this area.
