Patent EP-0434984-A2 (EP)
Inventor: LINDBERG KEITH J
IPC: H01L21/322
Filed: 1990-11-23
Abstract: A method for gettering metal atoms (28) from a subsequently contaminated silicon substrate (12) is disclosed. A smoothed or polished first surface (16) has a thin germanium silicon layer (20) deposited thereon. A silicon layer (24) is deposited onto the germanium silicon layer (20) to seal the layer (20) between the substrate (12) and the silicon layer (24). Electronic components (26) are fabricated on a second surface (14) of the silicon substrate (12) which causes the metal atoms (28) to contaminate the substrate as a result of contamination in normal processing (12). As the substrate (12) is heated during normal processing of the devices, metal atoms (28) in the substrate of a result of contamination, diffuse in the substrate (12) to the misfit dislocations at the germanium-silicon (20)/silicon interface.

Abstract: An apparatus and method for regulating the gap between a casting nozzle and a casting wheel in which the gap between the casting nozzle and the casting wheel is monitored by means of at least one sensing element protruding from the face of the casting nozzle. The sensing element is preferably connected to a voltage source and the casting wheel grounded. When the sensing element contacts the casting wheel, an electric circuit is completed. The completion of the circuit can be registered by an indicator, and the presence or absence of a completed circuit indicates the relative position of the casting nozzle to the casting wheel. The relative positions of the casting nozzle and casting wheel can thereby be selectively adjusted to continually maintain a predetermined distance between their adjacent surfaces.

Abstract: The process of synchronization and decomposition of asynchronous frames organized with octet-rows of bits, for the adaptation of speed carried out by an intermediate reception block for adaptation of speed of an integrated device for the adaptation of synchronous and asynchronous terminals according to the CCITT V.110 standard to an Integrated Services Digital Network, is carried out by storing one octet at a time in an 8-bit shift register (RSC8) and by using counters (RSA,RSB,RSC8) in order to store the current position of each octet within a respective asynchronous frame and by recognizing by means of other counters (CT80,CTNFR) the relevant bits of each octet, which are stored and switched to the respective elements for management and for control of the serial flow of data from the network to the terminal. From this, an architecture is derived, which is particularly simplified by means of the redimensioning of the registers which, instead of storing an entire frame, have to store only one octet at a time. Also, the delay undergone by the data in transfer by means of the block is reduced to the delay necessary for the shifting of a single octet. In fact, there will never be more than two octets at a time contained within the block instead of two frames or one, as would be necessary according to an architecture of conventional type. Two PLAs (RS2,RS3), each functioning with its own clock (CK0,CK1), manage and control the synchronization, the decomposition of the frames into octets and the addressing of the bits and, respectively, the flow of the data in input to and in output from the block in relation to said standard.

Abstract: A high resolution lithographic mask having a desired pattern is generated and used to replicate the pattern onto a film in a one-step process. 
     A film of phase-changeable material in one state is provided on a conductive substrate. By scanning tunneling microscope techniques, the state and thereby the conductivity or other property of the material in selected areas (a′-c′) of the film is changed to a second state to provide from the film a mask (19) having a desired pattern defined by crystalline areas. Amorphous material need not be removed from the mask. 
     To replicate the pattern on another film (16), the latter is placed on another conductive substrate (17); the mask is positioned (21p-21r) with its patterned side within electron tunneling distance (19p-19r) of said other film; and the pattern is replicated in a single step by applying a voltage between the mask and other film. The voltage charge on said mask is positive and negative on said other film to cause current to flow in the crystalline areas of said mask and, by electron flow from said film to the mask, eliminate backscat­tering and insure high resolution. 
     As the state changes (e.g., from crystalline to amor­phous) in the pattern areas of said other film, conductivity in the crystalline areas will progressively decrease and, by causing a corresponding reduction in current flow in the crystalline areas, minimize the risk of undesired broadening of exposed areas of said other film.

Abstract: A method for selective disclosure of the identity of a communication protocol under which an information packet originated, but without incorrectly identifying the protocol in a header accompanying the packet. If there is a need to conceal the identity of the underlying source protocol, a special anonymous protocol identifier is used, instead of the real protocol identifier, in the header of an encrypted information packet. Network monitors can then still provide accurate information concerning traffic on the network, without having this information distorted by the use of incorrect communication protocols. If there is a desire to reveal the underlying protocol, a subnetwork protocol frame format is used to store the protocol identity and signify whether the packet is encrypted. A packet that is of a non-subnetwork protocol can be encapsulated with a subnetwork header containing a special code signifying that there is an encapsulated packet and containing the original protocol identifier.

Abstract: . An improvement to the coated wire electrode has been accomplished via inclusion of a fortiophore into a sensor device. Sensor devices of the present invention include: an internal reference element ; a membrane ; and a fortiophore. Fortiophores are neutral charge carriers, which complex reversibly a corresponding ion of the conductive material used as the internal reference element. The fortiophore provides an electrochemically defined and reproducible solid internal contact between the membrane and the internal reference element. This solid internal contact, for example, in ion selective sensors, provides more reproducible potential offsets and better precision, and faster wet up. The fortiophores can be utilized in other electrochemical devices.

Abstract: There is disclosed an information recording apparatus capable of contour smoothing by modifying the data of an object pixel, referring to a surrounding area. There is employed a wide reference area, for example 11 x 9 pixels, divided into plural reference areas, all of which are referred to in the modification of the object pixel, and the modification of the object pixel is achieved by dividing the object pixel into plural sub pixels. In this manner the contour smoothing can be achieved in more natural manner, also in consideration of the curvature of the contour. Also the modification of the object pixel is inhibited if the original image is identified as a halftone image or certain characters, in order to avoid image blurring by such smoothing.
