Abstract: A method for fabricating a back-illuminated semiconductor imaging device on an ultra-thin semiconductor-on-insulator wafer (UTSOI) is disclosed. The UTSOI wafer includes a mechanical substrate, an insulator layer, and a seed layer. At least one dopant is applied to the semiconductor substrate. A first portion of an epitaxial layer is grown on the seed layer. A predefined concentration of carbon impurities is introduced into the first portion of the epitaxial layer. A remaining portion of the epitaxial layer is grown. During the epitaxial growth process, the at least one dopant diffuses into the epitaxial layer such that, at completion of the growing of the epitaxial layer, there exists a net dopant concentration profile which has an initial maximum value at an interface between the seed layer and the insulator layer and which decreases monotonically with increasing distance from the interface within at least a portion of at least one of the semiconductor substrate and the epitaxial layer.

Abstract: An integrated circuit system includes a substrate of an electrical insulating material having a surface. Mounted on the surface of the substrate is an IC, a semiconductor piece having therein a circuit, such as a microprocessor, having a plurality of functional blocks. Also mounted on the substrate are a plurality of power supply chips. Each of the power supply chips is connected through conductors and vias in the substrate to a separate functional block on the IC semiconductor piece. Each of the power supply chips forms part of a circuit, such as a DC-DC converter, which is capable of reducing a voltage supplied thereto to a lower voltage suitable for the particular functional block to which the particular power supply chip is connected. Thus, a single relatively large voltage fed to the power supply chips through conductors on the substrate is reduced by each power supply chip to a lower voltage suitable for the particular functional block of the IC semiconductor piece.

Abstract: The transaction card and method are used for securing a transaction conducted by mean of a credit card, a debit card, a security card or any other card including information to be read by a magnetic card reader. The card is provided with a counter which increments by 1 or any other number each time the card is activated. This counter value is used with a key string in a cryptographic algorithm to produce a signature. The resulting data stream is then transmitted to a computer. The computer may be one of the servers of a bank, a credit card provider, a security department, etc. Once the data stream is received, the computer finds the record of the card or cardholder using the identification number or any other number, then determines with the signature if the transaction is legitimate or not. The counter value is also verified.

Abstract: A power supply integrated module includes a metal substrate having a surface and a body of a dielectric material, such as a glass or ceramic, mounted on and bonded to the surface of the substrate. The body is formed of a plurality of layers of the dielectric material bonded together. Areas of a conductive material and a resistive material are coated on the surfaces of the layers of the body to form passive electronic components, such as capacitors, resistors and inductors. At least one transformer is on or in the body. The transformer and passive electronic components are electrically connected by conductive interconnects on the layers of the body and vias of a conductive material extending through the layers of the body to form a power supply integrated circuit. Active electronic components, such as diodes and transistors, may also be mounted on the body and electrically connected in the power supply circuit.

Abstract: The stability of a cholinesterase (particularly a cholinesterase solution impregnated into a porous material and air-dried) can be improved by: (a) buffering the cholinesterase solution with a zwitterionic buffer, e.g. a buffer having a sulfonic acid group and a protonatable amine group, and, preferably, (b) further drying the impregnated, air-dried porous material under a high vacuum (e.g. 0.01 mm Hg or less) at normal ambient temperatures. The most useful porous materials are sheet-like in nature; that is, they have only two major surfaces. An impregnated, sheet-like material of this invention can be used in a cholinesterase inhibitor detector kit. A typical kit of this type provides a simple means for detecting, inter alia, environmental cholinesterase-inhibiting pollutant, e.g. organophosphorous pesticides and nerve agents.

The layer has a resistance, when the rectifying contact is reverse biased, greater than that of the liquid crystal film, and, when the rectifying contact is forward biased, less than that of the film.
