    摘要: A dual layer resist configuration is employed for photopatterning high resolution conductive patterns on underlying polymeric or ceramic substrates, particularly substrates exhibiting surface roughness and non-planar design features such as channels, bosses and ridges. More particularly, a thin underlayer of ablatable photoabsorptive polymer is disposed on a metal coated substrate, after which a thicker layer of substantially transparent material is disposed over the polymer. A beam of laser energy, such as that produced by an ultraviolet excimer laser, is directed through the upper layer and is absorbed by the lower layer which is ablated and simultaneously removes the thick layer above it. This results in the ability to etch high resolution features on polymeric and other substrates, particularly copper coated polyetherimide circuit boards. The resist system is also applicable to VLSI wafers even though such wafers usually do not exhibit surface roughness on the scale generally considered herein. It is also equally applicable in various high density interconnect systems used for the direct connection of chip devices. A mask for patterning and a method for making it are also seen to be desirable because of the high laser energy densities generally desired for thorough ablation.

    摘要: Circuitry for enhancing the sharpness of bandwidth compressed television signals provides equalization in only the transmitter with no equalization required in the receiver. The transmitter includes a linear phase delay and edge peaking circuit, a low pass filter and an equalization circuit. The linear phase delay and edge peaking circuit includes a tapped delay line which provides weighted output signals for differential phase delays. The weighted output signals of the tapped delay line are differentially combined to provide a combined output signal. This combined output signal and a signal from the tapped delay line are supplied to a peaking circuit. A clamping circuit is connected to limit the amplitude of high level signals in the combined output signal so that small transitions are peaked to a greater degree than large transitions.

    摘要: An improved television bandwidth compression system allows two television programs to simultaneously utilize the bandwidth normally allowed for one television program. The basic bandwidth compression system comprises a transmitter which receives composite video signals from two program sources. The video processing circuitry of the transmitter provides an output signal wherein time-compressed chrominance information for the two program sources is sent on alternate lines during the normal horizontal retrace time and the luminance information for both program sources is sent during the active video time for each line. The receiver synthesizes a composite video signal of a selected program from the output signal transmitted from the transmitter. This basic system is improved by interlacing high and low bandwidth-limited luminance signals for alternating fields of each program in a manner such that when a high bandwidth-limited luminance signal is transmitted for one program, a low bandwidth-limited luminance signal is transmitted for the other program so that the total bandwidth allocated for the luminance signals is not exceeded.

    摘要: A low-cost electrical conductor is prepared by applying a mixture of a metallic powder and a polymer on a substrate, curing the polymer, effecting an augmentation replacement reaction to replace some of the metallic powder with a more noble metal in such a way that the total volume of deposited metal at the surface exceeds that of the original metal powder replaced, and thereafter applying a dielectric material to selected areas of the conductor thus formed. Imperfections such as pin holes and screen marks can be eliminated by heating the dielectric material to cause a degree of flow. Multiple layer interconnected conductors can be prepared by reapplying the mixture of metallic powder and polymer such that a portion thereof contacts the first prepared conductor, curing the polymer and effecting an augmentation replacement reaction with a metal which is more noble than the powder metal and the replacement metal of the first conductor.
