There is provided an active matrix substrate which enables to shorten a fabrication process of a pixel electrode, improve exposure precision by self alignment, and prevent leakage failures between pixel electrodes. On top of the interlayer insulating film, there are formed pixel electrodes, which are connected to the TFTs through contact holes piercing through the interlayer insulating film. The pixel electrodes are formed by applying on the interlayer insulating film a photosensitive transparent resin such as negative acrylic polymerized resin containing ITO, ATO or ZnO as transparent conductive particles, performing exposure from the back side of the substrate, and conducting development.

A wiring board includes an insulating substrate and a wiring pattern. The wiring pattern includes a main body and an upper end portion and is embedded in the insulating substrate while exposing at least the upper end portion on a surface of the insulating substrate. The upper end portion has a cross-sectional width smaller than that of a lower end portion of the wiring pattern embedded in the insulating substrate. The upper end portion is formed of a metal that is more noble than a metal of the main body of the wiring pattern.The wiring board having this structure achieves very high adhesion of the wiring pattern to the insulating layer.

A transformer comprises E-type core parts, a cylindrical core part, a second substrate, first substrates, and an insulating sheet. Each of the second substrate and the fist substrates includes a penetration hole. A coil is wired around the penetration hole. The second substrate is wrapped with an insulating sheet, together with the cylindrical core part. The second substrate and the cylindrical core part are sandwiched between cylindrical core legs of the core parts, through the insulating sheet.

A circuit substrate comprises a glass substrate 16, through-holes 18 formed through the glass substrate 16 and via electrodes 20 buried in the through-holes 18. An opening width of the through-holes 18 is minimum inside the glass substrate and is increased toward both surfaces of the glass substrate 16. Accordingly, the detachment of the via electrodes 20 can be prevented without increasing the surface roughness of the inside walls of the through holes, and stresses generated in the core substrate can be mitigated.

The invention relates to a majority current assisted detector device, comprising a semiconductor layer of a first conductivity type epitaxially grown on a semiconductor substrate, at least two control regions of the first conductivity type, at least two detection regions of a second conductivity type opposite to the first conductivity type, and a source for generating a majority carrier current in the semiconductor layer between the two control regions, the majority current being associated with an electrical field. The detection regions surround the control regions, thereby forming at least two taps. The device is configured for backside illumination and further comprises a well of the first conductivity type between the two detection regions for insulating the detection regions. The well comprises pixel circuitry elements.

An insulating motor housing includes first to fourth power supply elements stacked in their thickness direction to be spaced and insulated from each other and integrated with a housing body by insert molding. A power source connector using power source terminals of the second to fourth power supply elements as connector terminals is also integrated with the housing body.

The plating method comprises the step of forming a resin layer 10 over a substrate 16; the step of cutting the surface part of the resin layer 10 with a cutting tool 12; the step of forming a seed layer 36 on the resin layer 10 by electroless plating; and the step of forming a plating film 44 on the seed layer 36 by electroplating. Suitable roughness can be give to the surface of the resin layer 10, whereby the adhesion between the seed layer 36 and the resin layer 10 can be sufficiently ensured. Excessively deep pores are not formed in the surface of the resin layer 10, as are by desmearing treatment, whereby a micronized pattern of a photoresist film 40 can be formed on the resin layer 10. Thus, interconnections 44, etc. can be formed over the resin layer 10 at a narrow pitch with high reliability ensured.

Embodiments of the present invention disclose a thin film transistor, a method of manufacturing a thin film transistor, an array substrate and a display device, which may ensure electrical connection between source and drain electrodes and an active layer without configuring any through hole due to providing an etch stop layer between the active layer and the source and drain electrodes, a portion of the etch stop layer being in contact with the source and drain electrode is made of metal or metal alloy; and may ensure insulation between the source and the drain electrodes when the thin film transistor is turned-off, ensuring normal operation of the thin film transistor, by oxidating the portion of the etch stop layer at the position between the source and the drain electrodes as an insulating material. The etch stop layer may not only prevent the active layer from being damaged when etching the source and drain electrodes, but also prevent the active layer from other adverse effects from subsequent processes, such as adverse effects from water, hydrogen and oxygen, etc., thereby enhancing performance of the thin film transistor, just because of providing the etch stop layer between the active layer and the source and drain electrodes in the thin film transistor.
