Abstract:
To obtain a high mobility and a suitable threshold voltage in MOS transistors with channel dimensions in the deep sub-micron range, it is desirable to bury a strongly doped layer (or ground plane) in the channel region below a weakly doped intrinsic surface region, a few tens of nm below the surface. It was found, however, that degradation of the mobility can occur particularly in n-channel transistors owing to diffusion of boron atoms from the strongly doped layer to the surface, for example during the formation of the gate oxide. To prevent this degradation, a thin layer (11) of Si1-xGex inhibiting boron diffusion is provided between the strongly doped layer (10) and the intrinsic surface region (7), for example with x = 0.3. The SiGe layer and the intrinsic surface region may be provided epitaxially, the thickness of the SiGe layer being so small that the lattice constants in the epitaxial layers do not or substantially not differ from those in the substrate 1 in a plane parallel to the surface, while a sufficient diffusion-inhibiting effect is retained. Since SiGe has a diffusion-accelerating rather than decelerating effect on n-type dopants, the ground plane of a p-channel transistor in a CMOS embodiment is doped with As or Sb because of the low diffusion rate of these elements in pure silicon.
Abstract:
A flat display device, preferably of the PALC type, in which the plasma channels are formed by etching in a substrate laterally-spaced channels and bonding a thin dielectric sheet over the etched substrate. Adjoining each of the channels are shallow ledges, also formed by etching, which serve as recessed areas to receive enlarged ends serving as contact pads for each of the electrodes. Holes are formed in the thin dielectric sheet and contact material deposited on the bonded thin dielectric sheet such that the deposited material makes electrical contact with the underlying electrode contact pads and seals off the holes, which allows a plasma-forming atmosphere to be provided in the channels. This arrangement results in a glass-to-glass interface between the substrate and the thin dielectric sheet, which allows anodic bonding to be employed to assemble the two elements and thus eliminates the frit glass sealing process required in other constructions.
Abstract:
The electrochromic element comprises an electrochromic layer (22) whose transmission properties change when a voltage difference is applied across the element. Said electrochromic layer (22) comprises a first metal oxide of the group formed by WO3, MoO3, Nb2O5, MnO2 and ZrO2 (and combinations thereof) and a second metal oxide containing V2O5, TiO2 and/or ZnO. If the concentration of the second metal in the mixture ranges from 1 to 15 at. %, preferably from 3 to 10 at. %, the electrochromic layer (22) is transparent and colorless if no guest atoms are incorporated in the layer, and it is (color neutral) grey if a substantial concentration of guest atoms is incorporated in the layer. Electrochromic elements are provided, for example, on the outer surface of a display screen of a display device.

Abstract:
An interface device (3) is used to couple a first (101) and second (201) bi-directional signal path, such as I2C. The first bi-directional signal path (101) floats at a logic high level. Stations (110) coupled to the first signal path (101) are capable of generating a logic low level on the first signal path (101). To avoid that the system gets latched in a low state, a medium logic level is used on the first signal path (101). The interface device (3) generates the medium logic level on the first bi-directional signal path (101) in response to a low logic level on the second signal path (201). The interface device (3) generates on the second signal path (201) a low logic level in response to a low logic level on the first signal path and, otherwise, generates a high logic level. The stations (110) on the first signal path (101) detect the medium logic level and the low logic level as LOW and the high logic level as HIGH.
Abstract:
A lateral thin-film silicon-on-insulator (SOI) device includes a lateral semiconductor device such as a diode or MOSFET provided in a thin semiconductor film on a thin buried oxide. The lateral semiconductor device structure includes at least two semiconductor regions separated by a lateral drift region. By providing a substantially linear lateral doping profile in the lateral drift region, and by providing a conductive field plate on a linearly-graded top oxide insulating layer, a device structure is obtained in which conduction losses can be reduced without reducing breakdown voltage.

Abstract:
An apparatus is disclosed for positioning a head (34) relative to a plurality of tracks (T1, Tn) running parallel to each other in their longitudinal direction on a record carrier (1). First and second tracks (T1, T2) have first and second tracking signals (S1, S2) of specific frequencies recorded in them and third and fourth tracks (Tn-1, Tn) have third and fourth tracking signals (Sn-1, Sn) of specific frequencies recorded in them. The apparatus comprises a head (34) for reading the tracking signals, control signal generator means (36, 38) for generating a first control signal in response to the first and second tracking signals (S1, S2) and for generating a second control signal in response to the third and fourth tracking signals (Sn-1, Sn). A positioning unit (40, 42) for moving the head (34) in a direction transverse to said longitudinal direction, has an input for receiving said first and second control signals and for moving the head in response to said first and second control signals, so as to position the head (34) onto a fifth and sixth track (Ta, Tz) respectively. A position detection unit (48, 49, 56) for detecting the position of the head (34) in said transverse direction, has an output (58) for supplying a first and a second position signal when the head (34) is positioned onto said fifth and sixth track (Ta, Tz) respectively. In a calibration mode of operation the position of the fifth and sixth tracks are located and the generated first and second position signals are stored in a memory (60).
Abstract:
A virtual body modelling apparatus and method are described, in which a user's body is modelled in a virtual environment and animated to follow physical movements of the user. Stores (30, 32) hold data defining the virtual environment as well as features of the virtual body representation, including sequences of virtual body motions (for example a walking sequence for the legs of the virtual body) which sequences are initiated in response to one or more predetermined physical movements by the user, and animated by a display generator (28) providing images of the virtual environment to the user. Various forms of feedback to the user are provided, including force feedback where the user's physical movements are constrained in dependence on conditions within the virtual environment, visual feedback where the user's viewpoint of the virtual world is modified as a sequence of body motions is executed, and audio feedback (62) such as the sound of footsteps triggered at predetermined points in the sequence of motions.
Abstract:
Metal-oxide layers having a high delta max, such as in particular magnesium-oxide layers, are provided on a glass substrate, such as a selection plate or a channel plate, of an electronic display device by means of a spray-pyrolisis process. To this end, a solution of a metal salt, such as Mg acetate, in ethanol or another (organic) solvent and/or water is sprayed onto a substrate which is maintained at a temperature of 350-550 DEG C. In a display device which is provided with such a layer on the bottoms and walls of the channels of the channel plate, a minimum transport voltage of 50-100 V/cm is required.
