Abstract:
A method of forming a thin film transistor comprises providing first electrode layers (42) over a transparent substrate (40), the first electrode layers comprising a lower transparent layer (42a), and an upper opaque layer (42b). The first electrode layers are patterned to define a first electrode pattern in which an edge region of the transparent layer (42a) extends beyond an edge region of the opaque layer (42b). A transistor body region comprising a semiconductor layer (16) defining the channel area of the transistor and a gate insulator layer (18) is provided over the first electrode pattern (42). A transparent second electrode layer (46) is also provided. A negative resist (70) is exposed through the substrate (40), with regions of the negative resist layer (70) shadowed by the opaque layer (42b) of the first electrode pattern (42) remaining unexposed. These regions and the underlying second electrode layer (46) are removed to define a second electrode pattern which is substantially aligned with the opaque layer (42b) of the first electrode pattern (42). The method can be used for top or bottom gate TFTs and provides a self aligned gate structure with overlap between the source/drain and the gate, so that no additional processing of the semiconductor body is required.

The user can move the device (1) relative to the artery (7) until the feedback signal (Ufeedback) is given, and thus a correct positioning of the measuring unit (2) relative to the artery (7) is achieved in an easy manner.
Abstract:
A matrix array display device has an array of pixels (10) on a substrate (50) which each have a display element (20), for example an electroluminescent display element, and associated control circuit including a storage capacitor (36) and a light sensing element (40) connected thereto for regulating charge stored on the capacitor and responsive, for example, to light emitted from the display element so as to regulate operation of the display element. The light sensing elements (40) comprise thin film semiconductor devices each having a strip of semiconductor material (52) with laterally-spaced, doped, contact regions (53, 54) and the associated storage capacitor (36) is formed by a conductive layer (58) extending substantially transversely of the strip over one contact region with intervening dielectric material. A predetermined relationship between the storage capacitor and photosensitive device characteristics is then ensured even though dimensional variations in component layers may occur due to manufacturing tolerances. Preferably, the photosensitive device comprises a gated device whose gate extends over the semiconductor strip region intermediate the contact regions. The gate dielectric and storage capacitor dielectric may comprise parts of a common layer (56). Alternatively, the conductive layer may be provided at the side of the strip opposite the gate and used also as a shield for ambient light.
Abstract:
A garment 10, such as a pair of trousers, skirt or full-length coat, comprises an antenna 12 and means 14 for connection of the same to a portable electronic device 16 to permit wireless communications of said device 16 via the antenna 12. The antenna 12 is a longitudinal conductive element attached to the garment 10 in such an orientation as to be close to the ground and to extend substantially vertically when a wearer of the garment is in a standing position. The antenna orientation close to the natural ground plane gives improved reception for, e.g. FM radio broadcasts.
