Patent EP-0185941-A2 (EP)
Inventor: WRIGHTON MARK S
IPC: H01L51/30
Filed: 1985-11-23
Abstract: Several types of new microelectronic devices including diodes, transistors, sensors, surface energy storage elements, and light-emitting devices are disclosed. The properties of these devices can be controlled by molecular-level changes in electroactive polymer components. These polymer components are formed from electrochemically polymerizable material whose physical properties change in response to chemical changes. Examples of such materials include polymers which respond to changes in redox potential. Very stable, polymer-based electrochemical devices which are durable in an aqueous electrolyte over a wide pH range and which respond rapidly to chemical or electrical signals are formed by polymerization of thiophene or a derivative such as 3-methylthiophene. In one embodi ment, the device functions as an extremely sensitive sensor which measures changes in chemical concentration or pH. For example. a poly-3-methylthiophene-based device is sensitive to as little as 8 x 10-  16  moles of an oxidant which reversibly interacts with the polymer, including gas phase oxidants such as I 2 . In a variation of the polymer-based device, a catalyst such as a noble metal or an enzyme is dispersed on or within the conducting polymer matrix so that the device is responsive to chemicals such as H 2  and O 2  which the polymer would otherwise respond very slowly to. In another embodiment, a polymer-based electrochromic device consists of individually adressable microelectrodes coated with a polymer whose optical properties change in response to chemical or electrical signals. Very high resolution is achieved by separating the microelectrodes by distances on the order of 10,000 Angstroms. In still another embodiment, the polymer-based device functions as a capacitor with an energy density as high as 200-300 J cm 3  which can operate at frequencies as high as 100 Hz when the device is formed from a polymer of thiophene or a thiophene derivative. These very small, specific, sensitive devices provide means for interfacing electrical and chemical systems while consuming very little power, and may be incorporated into conventional integrated circuit designs.

Abstract: A collapsible or foldable plastic bottle circular bellows like configuration capable of manufacture on current plastic bottle manufacturing equipment with current plastic materials approved for contact with foods and beverages. The bellows over center and fold to retain the folded condition without external assistance thus providing a self-latching feature. In particular, the bellows of the bottle, when fully folded, cause the bottle to substantially fit within a cup fastened to the base of the bottle. The cup is generally formed by further extending the cup upward and increasing the diameter slightly in comparison with the reinforcing cup on current soda pop bottles.

Abstract: Disclosed is a method of producing torch-and-drill proof slabs, and their use in the construction of modular safe walls. The slabs are formed by casting a metal plate having one, planar side and an opposite side formed with a series of parallel. generally V-shaped recesses. The recesses are divided by elongated projections so that every sloping side-surface of a recess intersects with an upright side-surface of a respective projection along a ridge line. A series of elongated, springy V-shaped steel bars are made, having opposite pointed side-edges extending parallel to each other, at a distance somewhat larger than the distance between the facing ridge lines. The bars are forcibly wedged from above into the recesses so that the pointed edges become snapped-in between opposite ridge lines.

Abstract: Each IDT (inter-digital transducer) (22, 24) of a SAW (surface acoustic wave) device (20) is formed on a thin resistive doped silicon film having the same pattern as the IDT, which improves adhesion of the IDT to the substrate. The silicon film also constitutes electro-acoustic absorbers (26, 28) between the IDTs and edges (40, 42) of the substrate, and can have a linearly tapered edge adjacent to each IDT to suppress reflections at the absorber boundary. The SAW device is formed by sputtering silicon onto the substrate, subsequently forming the IDTs, and then etching the silicon from areas where it is not wanted.
