AI Technical Summary

Technical Problem

Existing deposition methods struggle to accurately and predictably transfer highly viscous functional materials, such as conductive polymers, onto substrates while maintaining precision and scalability, and there is a need for improved control over the deposition process to adapt to various applications.

Method used

A deposition system comprising a heater strip with serially arranged resistive heating elements, a power supply, a selection module, a voltage and current sensing facility, and a control unit, which allows for independent control of heat flux by alternately supplying power to the heating elements based on sensed voltage and current signals, ensuring uniform current distribution and precise heat application.

Benefits of technology

The system enables accurate and scalable deposition of functional materials with minimal electrical connections, allowing for precise control of heat flux and fluence, thereby ensuring reliable transfer of donor elements onto target surfaces without deformation or damage.

Abstract

A deposition system (1) is disclosed herein for heat induced deposition of a donor element (d1, d2,...,d6) from a donor surface (2s) onto a target surface (Ts). The deposition system comprises at least one heater strip (2), a power supply (3), a selection module (4), a voltage and current sensing facility (6) and a control unit (5). The at least one heater strip (2) comprises a plurality of serially arranged resistive heating elements (h1, h2,...) for heating respective zones (2s1, 2s2,...) of the donor surface (2s), the resistive heating elements having a temperature dependent resistance. The selection module (4) is configured to alternately supply an electric power from the power supply (3) to a selected one of the serially arranged resistive heating elements. The voltage and current sensing facility (6) is configured to provide sense signals indicative for a voltage and a current of the supplied electric power and the control unit (5) is configured to control a heat flux of each resistive heating element in response to the sense signals.
