The stencil design has been tailored so that the thermally actuated membrane reduces the gap between stencil and substrate. The membrane is locally heated during metal deposition to prevent aperture clogging, extending thus the stencil’s effective lifetime. Four consecutive depositions were performed in quasi-dynamic mode, i.e. by translating the stencil relative to the substrate in between deposition steps. The resolution of the transferred patterns on the substrate through the heated stencil is greatly improved compared to the case of the standard, non-heated stencil. After 200 nm evaporated Al, the pattern distortion is reduced by 70% and the main structure maintains 97% of its size as opposed to decreasing by 40% for the standard clogged stencil.text::conference output::conference paper not in proceedings
