  • Patent number: 10689808
    Abstract: The present invention refers to the use and creation of materials based on natural cellulose fibbers, synthetic fibbers, or mixed fibbers as physical support and storing medium or storage inducer of electrical and ionic charges in self-sustaining discrete or complementary field-effect transistors with non-volatile memory by using organic or inorganic active semiconductors for the manufacture of the channel regions that are deposited on the fibbers of the paper material as well as metals or passive semiconductors for manufacturing drain and source allowing the interconnection of fibbers, in addition to the gate electrode contact existing on the other side-face of the paper, p or n type respectively, in monolithic or hybrid forms.

  • Patent number: 8987097
    Abstract: High performance thin-film, transistors are entirely processed at temperatures not exceeding 150° C., using amorphous multi component dielectrics based on the mixture of high band gap and high dielectric constant (K) materials. The sputtered or ink jet printed mixed dielectric materials such as Ta2O5 with SiO2 or Al2O3 or HfO2 with SiO2 or Al2O3 are used. These multicomponent dielectrics allow producing amorphous dielectrics to be introduced in high stable electronic devices with low leakage currents, while preserving a high dielectric constant. This results in producing thin film transistors with remarkable electrical properties, such as the ones produced based on Ga—In—Zn oxide as channel layers and where the dielectric was the combination of the mixture Ta2O5:SiO2, exhibiting field-effect mobility exceeding 35 cm2 V?1 s?1, close to 0 V turn-on voltage, on/off ratio higher than 106 and subthreshold slope below 0.24 V dec?1.
