    摘要： A dual dielectric structure is employed in the fabrication of thin film field effect transistors in a matrix addressed liquid display to provide improved transistor device characteristics and also to provide both electricial and chemical isolation for material employed in the gate metallization layer. In particular, the use of a layer of silicon oxide over the gate metallization layer is not only consistent with providing the desired electrical and chemical isolation, but also with providing redundant gate metallization material to be employed beneath source or data lines for electrical circuit redundancy. Gate line redundancy is also possible. The electrical and chemical isolation provided by the dual dielectric layer reduces the possibilities of short circuits occurring in the display. The absence of short circuits together with the improved redundancy characteristics significantly increase manufacturing yield. As display sizes increase, the yield problem becomes more and more significant, generally growing as the square of the diagonal measurement of the screen. The structure in the present invention also significantly reduces gate leakage current. In the process and structure of the present invention, gate electrode material is separated from semiconductor material by the aforementioned dual dielectric, typically comprising layers of silicon oxide disposed beneath a layer of silicon nitride which is, in turn, disposed beneath the active amorphous silicon semiconductor material.

    摘要： Electron optics apparatus, for use in electron-beam lithography, electron-beam-addressable memory tubes and the like, utilizes a tri-potential collimating condenser lens and a multi-element matrix lens of the "flys eye" type with coarse deflection elements positioned therebetween to deflect the collimated electron beam from the condenser lens to the appropriate aperture in the matrix of lenslets. The condenser lens electrode and matrix lens electrode closest to one another, as well as the coarse deflection electrodes therebetween, are substantially the only elements in the apparatus which float at a relatively high electrical potential, thereby simplifying the requirements of peripheral circuitry while retaining the advantages of the "flys eye" matrix lens.

    摘要： A memory plane for an archival, non-volatile mass storage memory has a planar semiconductor diode with each of a plurality of small P-N junction diodes alloyed into the surface of its fabricated layer responsive to a selectively-actuated scanned energy beam at each location corresponding to a first binary value in a planar array of data sites. Formation of a P-N junction is prevented at each of the remaining sites of the planar data array to provide storage of data having the remaining binary value.Several alternative methods for formation of the alloy junction surface diodes are disclosed.

    摘要： An improved fine deflection, for use in an electron beam optical system, utilizes a magnetic deflector positioned adjacent to the surface of the target most remote from a matrix lens, which is positioned between the target and an electron beam emitter. The matrix lens is a single plate having multiple apertures forming matrix lenslets and has an electron beam accelerator positioned between the lens and the target for uniform acceleration of the electron beam passing through a selected one of the lenslets.
