Overview of the deposition and stamping procedure. (1) A vinyl tape mask is cut based on the desired selective bonding pattern. (2) This mask is applied to a PDMS slab that will act as the stamp. (3) Deposition of PFTCS occurs in a low-cost vacuum desiccator. (4) The tape mask is removed from the stamp, leaving the PFTCS only in the exposed area. (5) Heat and force are used to transfer the PFTCS from the stamp to the desired substrate. (6) After transfer, the stamp shows apparent signs of transfer to the substrate for easy quality assurance checks.
