µ-Contact Dispensing System
The Micro-Contact-Printing system µ-CP2.1 combines silicon- and PDMS- micro-systems technology where the silicon based master-chips are used to cast the PDMS elastomeric stamps.
The compact desktop instrument prints micrometer and submicrometer patterns in a semi automatic way.
Microcontact-Printing transfers regular patterns like lines, rectangles, donuts to the target substrate. The PDMS stamps are immersed in or rolled onto the sample. This process is called "Inking". Then the stamp is pressed against the target controlled by air pressure.
The machine functionalizes up to four stamps by inking and drying. Subsequently each stamp touches down onto the target substrate. It is arranged on a vernier drive. Thus different patterns from different materials can be well aligned to each other.

GeSiM µ-Contact Printing Process
The deflected PDMS-stamp membrane is in a convex shape
The convex stamp-membrane is positioned in the direction of the substrate to generate a initial bond contact between stamp and substrate
The convex stamp travels in µ-meter step resolution into the substrate direction to create the bond wave (visible in this video attached)
The stamp motion finishes when the whole stamp-membrane gets in contact to the substrate. The pressure controlled stamp chamber and the
homogeneous contact between stamp and substrate cause isostatic force effects that
are given over the whole stamp, which is controlled using the pressure in the stamp
chamber. This "roof collapse effect" ensures very accurate printing.
