The laboratory is equipped with a cleanroom for the realization of devices for  nano and micro (opto) - electronics, micro electro mechanical systems (MEMS / MOEMS) and microfluidics. Currently the complete line of process is possible on 3” wafers but there is the possibility to work, for some processes, on larger or smaller or uneven substrates. In general, the present apparatus allows to realize:

• nano and micro electronics devices on active structures of III-V materials or on substrates of different nature such as silicon, alumina, sapphire, glass or flexible substrates such as Kapton and PDMS;
• bulk and surface micromachining of silicon and SiC and organic materials (PDMS);

The areas certified in class ISO5, ISO6 and ISO7 total more than 150m² to which about 100 m² of grey areas are added. Inside the cleanroom, a staff of 6 units  normally operates, and other 6 units are part time.

Optical lithography bay

It contains all the necessary equipment for photolithography and cleaning of the samples (room size: 25m2  class : ISO 5).
