In this study, we investigated Ar/N2-plasma sputtering gas pressure dependence on the LaBxNy insulator formation. The floating-gate memory with N-doped LaB6/LaBxNy stacked layer was examined for top-gate type Si device and back-gate type organic semiconductor device. The sputtering gas pressure was changed from 0.19 Pa to 0.47 Pa by changing the Ar/N2 gas flow ratio from 4/2.8 sccm to 10/7 sccm for LaBxNy deposition. In the case of MIMIS diode for top-gate type Si device at sputtering gas pressure of 0.19 Pa, larger memory window (MW) of 0.56 V was obtained with higher relative dielectric constant (εr) of 19.5 due to the improvement of film quality compared to sputtering gas pressure of 0.47 Pa which indicated the MW of 0.4 V and εr of 17.2, respectively. The pentacene-based floating-gate back-gate type organic field-effect transistor (OFET) was fabricated with α-rubrene passivation layer. In the case of sputtering gas pressure of 0.19 Pa, larger MW of 0.68 V was obtained with saturation mobility of 2.2×10-2 cm2/(Vs) and subthreshold swing of 199 mV/dec. |
