Patent EP-0319213-A2 (EP)
Inventor: LIU RUICHEN
IPC: H01L21/8238
Filed: 1988-11-25
Abstract: A new method for fabricating a semiconductor device, e.g., a MOS or MES IC, is disclosed. In accordance with the new method, a semiconductor device is formed, at least in part, by forming a material region (60,70) which includes metal, e.g., elemental metal or a metal-containing compound, on a semiconductor substrate(10). One or more dopants are implanted into the material region, and the substrate is heated in order to diffuse the dopants out of the material region and into the substrate, thus forming a dopant-diffused substrate region, e.g., a source or drain (100,110). The new method involves implant conditions which yield a material region-to-substrate specific contact resistance equal to or less than about 10⁻⁶Ω-cm⁻². In addition, the new method involves heating temperatures and heating times which yield a dopant-diffused substrate region having a depth, relative to the top of the material region, equal to or less than about 0.2 micrometres.

Abstract: A unipolar original electrical signal (1) is encoded by alternate mark inversion (2) and combined with a DC bias cur­rent (4) for injection of a semiconductor laser (7) to produce a bipolar FSK optical signal (8) that is transmitted to a re­ceiver. At the receiver, the received signal (8) is coupled with optical local power (15) and fed to an optical/electrical transducer (18), preferably a semiconductor, to produce an electrical signal (19) that is demodulated to produce the ori­ginal unipolar signal (27). The demodulator (28A) may be of different types, for example employing delaying part of the amplified electrical signal and mixing the delayed part with the original signal for passage of the combined signal through a low pass filter (24); with proper selection of the delay, an AMI decoder is not needed. The demodulator may also be of the type that has one or more band pass filters to respectively separate the positive mark, space and negative mark signals that may thereafter be added. Filtering and polarization beam splitting may also be used in the demodulator for improving the signal-to-noise ratio and preventing other types of degradation.

Abstract: When a strip (2) of e.g. hot steel is rolled by a rolling or roughing mill, scale develops on the surface of the strip (2) which must be removed. The strip (2) is passed over a bending roller (5) which bends the strip (2) and causes cracks in the scale. Then water is injected (11) on to the strip (2) to wash the roller (5) to lift off the scale. Inertia then causes the water and scale to leave the surface of the strip (2) and pass to a collection means (12) whose water collecting surface (14) is out of contact with the strip (2) and on the opposite side of the bending roller (5) from the water injection (11). In this way the time of contact of the water with the strip can be kept short and the strip is not damaged by contact with the collection means (12). A further bending roller (6), water injection means (15), and collection means (16) may be provided to remove scale from the other side of the strip (2).

Abstract: The present invention dissipates the heat generated by high powered VLSI chips to a heat sink in a very efficient manner, providing a thermal resistance heretofore not possible in heat conduction module cold plate type systems. A finned internal thermal device (14) having a flat bottom contacts the chips (11), while corresponding fins in a finned cooling hat mounted to a cold plate form gaps into which the fins of the finned internal thermal devices are slidably mounted. A preferred double cantilever spring (22) between the finned internal thermal devices and fins of the finned cooling hat and a compliant thermally conductive interface such as synthetic oil between the chips and flat base of the finned internal devices provide efficient, non-rigid interfaces throughout the system, while assuring good thermal contact between the system components. The present high conduction cooling module allows for the simple incorporation of side biasing means and a grooved chip interface on the finned internal thermal devices to provide enhanced thermal performance if required.
