Medjed

The MEDJED system is a photolithography system - this means its primary function is to expose a (flat-ish) substrate to patterened light. The substrate will need to be coated in a layer of light-sensitive material known as photoresist. This resist layer in turn will undergo chemical reactions upon exposure to UV light, either rendering areas that were exposed soluble or insoluble to a (liquid) chemical developer. After development of the exposed photoresist layer, some areas of the substrate will remain coated in the photoresist, while others will be free of it. This is the starting point for further patterning steps and is the backbone of modern microfabrication.

The MEDJED system targets a 5um pixel size in its current design. The total project cost is targeted to be 2000-2500 euro.
