The hot plate is a system with a controlled heated plate used for baking and curing thin films and coatings, providing even temperatures across a surface. In conjunction with the Laurell spin coater, the system can be used to fabricate polymer coatings and multi thin film layers.

The EMS 1000-1 hot plate (Electronic Micro Systems Ltd.) integrates a P.I.D. temperature controller with digital readout and an aluminium plate for substrate with a maximum size of 150 mm. The hot plate is able to control the temperature across the surface in a range between room temperature and 200°C, with a temperature uniformity across the working surface of 1%. This gives the opportunity to set programmable ramps and dwells of temperature.
