摘要： A method is provided for fabricating molecular electronic devices comprising at least a bottom electrode and a molecular switch film on the bottom electrode. The method includes forming the bottom electrode by a process including: cleaning portions of the substrate where the bottom electrode is to be deposited; pre-sputtering the portions; depositing a conductive layer on at least the portions; and cleaning the top surface of the conductive layer. Advantageously, the conductive electrode properties include: low or controlled oxide formation (or possibly passivated), high melting point, high bulk modulus, and low diffusion. Smooth deposited film surfaces are compatible with Langmuir-Blodgett molecular film deposition. Tailored surfaces are further useful for SAM deposition. The metallic nature gives high conductivity connection to molecules. Barrier layers may be added to the device stack, i.e., Al2O3 over the conductive layer.

摘要： Disclosed is a method of producing a suitable array of semiconductor chips or other objects for visual inspection. Semiconductor chips on the order of a few hundred microns on each side are placed onto a mesh screen in a container, then submersed in deionized water, so that the chips begin to float and the fluid never covers the upper surfaces of the chips. Gently swirling the fluid causes the chips to orient in the center of the container. Continued swirling aligns the chips into an orderly array of rows and columns.

摘要： A technique is provided for forming a molecule or an array of molecules having a defined orientation relative to the substrate or for forming a mold for deposition of a material therein. The array of molecules is formed by dispersing them in an array of small, aligned holes (nanopores), or mold, in a substrate. Typically, the material in which the nanopores are formed is insulating. The underlying substrate may be either conducting or insulating. For electronic device applications, the substrate is, in general, electrically conducting and may be exposed at the bottom of the pores so that one end of the molecule in the nanopore makes electrical contact to the substrate. A substrate such as a single-crystal silicon wafer is especially convenient because many of the process steps to form the molecular array can use techniques well developed for semiconductor device and integrated-circuit fabrication.

摘要： Bistable molecules are provided with at least one photosensitive functional group. As thus constituted, the bistable molecules are photopatternable, thereby allowing fabrication of micrometer-scale and nanometer-scale circuits in discrete areas without relying on a top conductor as a mask. The bistable molecules may comprise molecules that undergo redox reactions, such as rotaxanes and catenanes, or may comprise molecules that undergo an electric-field-induced band gap change that causes the molecules, or a portion thereof, to rotate, bend, twist, or otherwise change from a substantially fully conjugated state to a less conjugated state. The change in states in the latter case results in a change in electrical conductivity.

摘要： A cross point memory array is fabricated on a substrate with a plurality of memory cells, each memory cell including a diode and an anti-fuse in series. First and second conducting materials are disposed in separate strips on the substrate to form a plurality of first and second orthogonal electrodes with cross points. A plurality of semiconductor layers are disposed between the first and second electrodes to form a plurality of diodes between the cross points of the first and second electrodes. A passivation layer is disposed between the first electrodes and the diodes to form a plurality of anti-fuses adjacent to the diodes at the cross points of first and second electrodes. Portions of the diode layers are removed between the electrode cross points to form the plurality of memory cells with rows of trenches between adjacent memory cells to provide a barrier against crosstalk between adjacent memory cells. The trenches extend substantially to the depth of the n-doped layer in each diode. A process for fabricating the memory array includes formation of the anti-fuse above the diode in each memory cell and extending the passivation material into the trenches as the isolation material. Alternately, the diode may be formed above the anti-fuse, so that the trenches may be substantially more shallow. In addition, a process is provided for fabricating a cross point memory array having a plurality of memory cells on a substrate, each memory cell including a diode adjacent to a line electrode, including etching together in one fabrication step the boundaries extending along a first direction of each of the diodes and each of the line electrodes to form multiple rows of the diodes and the line electrodes extending in the first direction.
