Integration of new and improved materials for smart millimeter-wave sensors
Project Director: Dr. Lucian TRUPINA
The MASTERS project is focusing on innovative solutions for the improvement, above the current state-of-the-art, of both security and power consumption of millimeter-wave sensors, by exploiting the permitivity agility of ferroelectric materials. Indeed, the integration of these intelligent and functional materials in practical devices will meet the current requirements for highly reconfigurable, integrated, safe, efficient and low power-consuming devices. The final goal of the project is the design and realization of original on-chip reconfigurable sensors as practical and efficient demonstrators for industrial applications, as a first step toward the establishment of innovative and highly-efficient market-oriented devices. Thanks to the structural, technological advantages and background of the MASTERS multi-national consortium and the expertise of the industrial partner, the project will create smart and user friendly solutions for sensing devices.
The main objective of the MASTERS project is the introduction of on-chip reconfigurable antennas at millimeter frequency bands (57 GHz to 64 GHz), while developing the concept into a marketable product.

Growth of iridium (Ir) and SrRuO3 (SRO) bottom electrodes and Ba1-xSrxTiO3 (BST) with x = 0.45 and (1-x) (Bi0.5Na0.5TiO3) -xBaTiO3 (BNT-BTx) with x = 0.08 or 0.04 ferroelectric thin films was studied.
Ir thin films were grown on silicon (001) and (111) substrate and on MgO (001) and (111) while SRO thin films were grown on MgO (001), (111) and (110) substrates. Structural and morphological investigations revealed that the degree and quality of crystalline orientation of iridium thin films are strongly dependent on the MgO substrate temperature and crystallographic orientation. Iridium layers deposited on silicon substrate shows a preferential orientation in the [111] direction which is not dependent on the substrate crystal orientation or temperature.
SRO thin films deposited on the MgO(100) and MgO(111) substrates shows no preferred orientation while the films deposited on the MgO(110) substrate have a tendency to texture in [110] direction.
Single phase BST thin films with random orientation were grown on silicon substrates with iridium electrode. The temperature where the ferroelectric–paraelectric phase transition occurs (Curie temperature) was -12 ° C, which indicates that the samples are in paraelectric phase at room temperature. The value of dielectric constant (er) was about 968 at room temperature.
Densified and crack-free BNT-BT thin films were grown on silicon substrate with iridium electrode by sol-gel method. A "butterfly" type hysteresis loop is observed in C-V characteristics of Pt/BNT-BT/Ir/Si capacitors. This result indicates that the film is in ferroelectric phase. The value of dielectric constant value was 350.
Hetero epitaxial iridium thin films have been grown on MgO(001), (110) and (111) substrates.
