In this paper, MgO (Magnesium Oxide) based biosensors were fabricated for chemical solution sensing with high pH sensitivity. CF4 plasma treatment was carried out to shape nanostructures and stabilize the material properties of the MgO membrane. For the CF4 plasma treatment of MgO films and deposition of silicon based films, Samco PECVD system PD-220N was used.

Samco offers PECVD systems for plasma deposition of SiO2, SiNx, a-Si, DLC and etc. These films are used for passivation, barrier film and other purposes in various research fields.
