A new procedure to directly pattern a luminescent porous silicon substrate by dry‐removal soft lithography is outlined. The ability to transfer a removed microstructure of porous silicon to a free‐standing flexible polymer film is also demonstrated, and by removing strips in orthogonal directions, an array of PSi pillars is produced (see Figure).
