Abstract: A method for increasing the wirability of complementary metal oxide semiconductor (CMOS) differential cascode voltage switch (DCVS) logic circuits which comprises designing the circuitry to permit as many of the internal tree connections as possible to be wired using diffusion techniques. The method utilizes differential pair and load microblocks which have been designed so as to allow mirroring on a vertical center line. Utilizing the availability of mirroring for individual pairs plus relocation of individual pairs in the logic tree the crossings may be largely eliminated in a shortened period. It utilizes a step by step row and column analysis of the initial or starting tree design resulting from the basic Boolean logic to be performed by the particular circuit and makes required load mirroring and differential pair relocation decisions in an iterative process. The transistor pairs and load devices may be mirrored about a vertical center line.

Abstract: Plane polarized light is reflected from a surface of a sample film to produce an elliptically polarized reflected beam. The reflected beam is passed sequentially through a rotating one-quarter wave plate and a fixed analyzer which transmits a beam whose intensity varies as a function of the rotational angle of the plate. The transmitted beam impinges upon a photodetector which produces an electric signal proportional to the intensity of the transmitted light. The rotating one-quarter wave plate cyclically varies the polarization of the beam, so that the electrical signal, when numerically Fourier analyzed, provides Fourier coefficients having both sin .DELTA. and cos .DELTA. terms, where the ellipsometric parameter .DELTA. is the instantaneous phase difference between the parallel (R.sub.p) and perpendicular (R.sub.s) components of the electric vector of the elliptically polarized reflected beam; therefore, the phase difference .DELTA. is uniquely and unambiguously defined in a single measurement.

Abstract: An improved lithographic printing plate includes a substrate layer of a nonconducting, hydrophobic polyester, an intermediate film of conducting, hydrophilic material such as aluminum and a top protective film of relatively hard hydrophilic dielectric material, such as aluminum oxide. A printing image is formed in the lithographic printing plate by an electroerosion process wherein erosion electrodes are pulsed with voltage to break down the dielectric in areas adjacent to the erosion electrodes and to evaporate or otherwise remove corresponding portions of the conducting film, thereby creating holes that extend through the dielectric and conducting films and that expose portions of the surface of the underlying hydrophobic substrate.
