摘要： A heterojunction bipolar transistor has an emitter which comprises an expitaxial layer of silicon grown on a silicon and germanium base layer. The active region of the transistor comprises a semiconductor having a silicon/silicon and germanium strained lattice and the silicon and germanium base layer is grown on a silicon substrate whilst maintaining commensurate growth. The lattice strain is such as to produce a predetermined valence band offset at the emitter/base junction. The mobility in the base is also enhanced over that of an unstrained alloy of the same composition.

摘要： A method of fabricating an optical waveguide includes the initial step of forming a strip (3) of doped silicon in a silicon substrate (1). The substrate (1) is then subjected to a porous anodisation step, whereby the doped silicon strip (3) is converted to a porous structure. The substrate (1) is then nitrided, whereby the porous structure (3) is converted to a substantially fully-dense silicon oxynitride matrix (3'). A doped silicon region (4) is then formed around the silicon oxynitride matrix (3'). The substrate (1) is then subjected to a second anodisation step, whereby the doped region (4) is converted into a porous structure (4'). The substrate (1) is then oxidised whereby the porous structure (4') is converted to a substantially fully-dense silicon dioxide matrix. Finally, an oxide layer (5) may be formed on top of the substrate (1).

摘要： In order to make a micromechanical switch a first sacrificial layer is formed on a substrate (1). A second sacrificial layer (4) is then formed as an island on the first sacrificial layer (3). A switch element layer (7) of resilient material is then formed on the second sacrificial layer (4), and the outline (5) of a switch element (8) is defined on the switch element layer (7). The outline (12) of a window is then defined, and the second sacrificial layer (4) is etched through the window using an etchant which laterally undercuts that portion of the switch element layer (7) which is to form the switch element (8). The first sacrificial layer (8) is then etched through the window defined by the etched second sacrificial layer to define a cavity (13) beneath said portion, thereby defining the switch element (8).

摘要： To provide secure communications to a PBX (20,22) the PBX is connected to two different local exchanges of the PSTN. On recognising a telephone number designating calls to the PBX, service switching points (2) apply to service control points (8) for route translations. The SCP (8) directs calls though the network alternately to network connections on one DLE (say 1c) and then to the other DLE (1b). In the event of a predetermined number of call failure on one of the routes, all subsequent calls are directed to the other route until a predetermined number of call failures occurs on the other route whereupon consecutive calls are again offered alternately

摘要： In a digital payment system a sequence of random numbers are stored at a payment server (600). A set of digitally encoded random numbers derived from the stored sequence are issued to the user in return for payment. The tokens are stored in a Carnet (100). The user can then spend the tokens by transferring tokens to a merchant (500), for example to an on-line service provider. The merchant returns each token received to the payment server. The payment server authenticates the token and transmits an authentication message to the merchant. The merchant, payment server and user may be linked by Internet connections.
