摘要:
A production method of nonlinear MIM device (50) including a Ta electrode layer (16), an anodized layer (18) and a Cr electrode layer (20). A tantalum oxide film (14) is first disposed on a transparent substrate (12), the Ta electrode layer (16) is then disposed on the former, and the anodized layer (18) is disposed on the Ta electrode layer (16). Thereafter, a heat treatment is carried out, including a final cooling step in an atmosphere containing steam. Thereafter, the Cr electrode layer (20) is disposed to finish a nonlinear MIM device (50). Owing to the heat treatment in the steam-containing atmosphere, the nonlinear characteristics of the MIM device can be improved, and its off-time resistance can be also improved.

A detector (10A) for detecting electromagnetic radiation incident thereon over a desired range of frequencies exhibits a given responsivity and includes an output and first and second non-insulating layers (14), which layers are spaced apart such that a given voltage can be applied thereacross. The first non-insulating layer (12) is formed of a metal, and the first and second non-insulating layers are configured to form an antenna structure for receiving electromagnetic radiation over the desired range of frequencies. The detector further includes an arrangement disposed between the first and second non-insulating layers and configured to serve as a transport of electrons between the first and second non-insulating layers as a result of the electromagnetic radiation being received at the antenna structure. The arrangement includes at least a first layer of an amorphous material (16) such that the transport of electrons includes, at least in part, transport by means of resonant tunneling, and such that at least a portion of the electromagnetic radiation incident on the antenna is converted at the output to an electrical signal having an intensity which depends on the given responsivity.

摘要:
Thin-film switching elements (20, 21) of a display device or the like include a first electrode (22, 23) on a substrate (11) and a layer of switching material (24, 25) on the first electrode. These switching elements may be semiconductor pin or Schottky diodes, or MIMs, or TFTs. The switching material is typically α-Si:H in the case of the semiconductor diodes and TFTs, and tantalum oxide or silicon nitride in the case of the MIMs. An auxiliary layer (28, 29) of insulating material is provided between the first electrode (22, 23) and the layer of switching material (24, 25), leaving an edge (30, 31) of the first electrode uncovered, so that the layer of switching material is connected to this edge only. The switching elements with this construction can be patterned using an inexpensive proximity printer, and have a low capacitance value, so counter-acting kickback and crosstalk which can occur in a switching matrix, e.g. in the display of television pictures.
摘要:
A method for producing metal wirings on an insulating substrate is disclosed. The method comprises the steps of forming a metal wiring layer of a predetermined shape on a predetermined position of the insulating substrate, the metal wiring layer being made of a metal capable of being oxidized; implanting the metal wiring layer with an impurity element; and forming an insulating layer by oxidizing the surface of the metal wiring layer after implanting the impurity element.
