摘要:
A current-controlled, bistable threshold or memory switch comprises a polycrystalline metal-organic semiconductor sandwiched between netallic electrodes. Films of either copper or silver complexed with TNAP, DDQ, TCNE, TCNQ, derivative TCNQ molecules, or other such electron acceptors provide switching between high and low impedance states with combined delay and switching times on the order of 1 nanosecond. Switching behavior of a complex of the present invention is related to the reduction potential of the acceptor molecule.
摘要:
Microcircuits composed of a plurality of alternating conducting and insulating regions are formed in a substrate of an organic quasi-unidimensional conductor such as .DELTA..sup.2,2 bi-4,5-dimethyl-1,3-diselenolylidene upon irradiation of the substrate with a precise beam of electrons having an energy of at least 1 keV, preferably at least 8 keV, which forms the insulating regions. When exposed to cryogenic temperatures the non-irradated conducting regions become super conducting. Using electron beam irradiations, sub-micronic resolution as low as 100 .ANG. can be achieved. Microcircuits having Josephson junctions and superconducting quantum interference devices are described.
摘要:
Materials that change crystal structure upon radiation with a beam of electrons have been found. These materials, such as perylene dianhydride, naphthalene dianhydride, and perylene tetracarboxylic diimide based compounds undergo a transformation from one crystalline structure to another upon exposure to energetic electrons. This transformation causes a change in optical, electrical, and solubility properties. In this manner, these materials are useful as resists for delineating patterns, as optical storage media, and/or in processes for producing patterns of conductive materials such as employed in semiconductor technology.

摘要:
A semiconductor device and method having a low-permittivity material between closely-spaced leads in order to decrease unwanted capacitance, while having a more structurally strong dielectric between widely-spaced leads where capacitance is not as critical. Metal layer 14 is deposited on a substrate 12 of a semiconductor wafer 10, where the metal layer 14 has a first portion 15 and a second portion 17. Widely-spaced leads 16 are formed in the first portion 15 of the metal layer 14, and a first structural dielectric layer 26 is deposited on at least the widely-spaced leads. Closely-spaced leads 18 are formed in the second portion 17 of the metal layer 14, and low-permittivity material 34 is deposited between closely-spaced leads 18. A second structural dielectric layer 36 is deposited on at least low-permittivity material 34 and closely-spaced leads 18. An advantage of the invention includes improved structural strength by placing structurally weak low-permittivity material only where needed, in areas having closely-spaced leads.

Disclosed is an organic electroluminescence device having a light emitting layer or a light emitting layer and a charge transport layer disposed between a pair of electrodes at least one of which is transparent or semi-transparent, the light emitting layer comprising a conjugated polymer having a repeating unit represented by the general formula (1):--Ar.sub.1 --CH.dbd.CH-- (1)where Ar.sub.1 represents an aromatic hydrocarbon group having 6 to 14 carbon atoms or a nuclear-substituted group in which the aromatic hydrocarbon group is substituted by one or two selected from the group consisting of hydrocarbon groups having 1 to 22 carbon atoms and alkoxy groups having 1 to 22 carbon atoms. According to the present invention, the use of a polymer intermediate of the conjugated polymer or the conjugated polymer soluble to a solvent as a light emitting material, a charge transport material or a buffer layer to an electrode enables an EL device having a large area to be easily made.
摘要:
A reliable multilevel interconnection structure is attained by using polyacetylene layers. Nondoped polyacetylene is dielectric but is conductive when it is doped with an impurity such as AsF.sub.5, which makes it possible to eliminate the necessity of opening a contact hole or through hole in an insulating layer in a process for manufacturing a multilevel interconnection structure so that a disconnection and/or short circuit does not occur due to the evenness of the layers even if the layer of numbers is increased.
摘要:
In the manufacture of integrated circuits, an undoped wide band-gap semiconductor is used for the insulating layer to isolate the silicon substrate from the metal interconnection pattern. To provide conductive vias through the insulating layer for connection to the source and drain of the transistors of the circuit, the wide band-gap semiconductor is implanted with a dopant selectively in the portion overlying the source and drain for making the implanted portion of low resistivity and of the conductivity type of the source and drain. Preferably, carbon is the wide band-gap semiconductor and nitrogen is the dopant implanted.
