  • Field emission display having elongate emitter structures
    Patent number: 5982081
    Abstract: Field emitter structures are described for use in arrays forming field emission displays. The field emitter structures may be either single or perferably double-gate structures. To enhance the field emission current density the emitters are formed so as to be elongate so as to form a race-track shape. The emitter layer may also be provided with sharply defined edges in order to improve electron emission.

  • Thin film transistor
    Patent number: 5869847
    Abstract: A thin film transistor (TFT) comprises a n.sup.+ source region and a p.sup.+ drain separated by an undoped offset region, or the complementary structure with a p.sup.+ source and a n.sup.+ drain. By means of this arrangement in the offset region is conduction is by way of both electron and hole carriers and the offset region is conductivity modulated. The TFT of the present invention has lower on-resistance than a conventional thin film transistor.
