Abstract: Plasma-resistant polymeric materials are prepared by reacting a polymeric material containing reactive hydrogen functional groups with a multifunctional organometallic material containing at least two functional groups which are reactive with the reactive hydrogen functional groups of the polymeric material, such as hexamethylcyclotrisilazane.

Abstract: A system of establishing a conductive via path between spaced interlevel conductors. Successive layers of metallization separated by a dielectric are built. The vias are opened in one step to eliminate interlevel mashing. The system employs annular pads at locations where contact may be established to another wiring level. The vias are self-aligned and taper from top metal to first level contact. The system is applicable both chip-wise and carrier-wise.

Abstract: A multi-layer structure that includes a transparent dielectric substrate, a layer of a nickel-containing steel alloy, and a layer of copper and/or chrome.

Abstract: A coherent laser beam having a possibly non-uniform spatial intensity distribution is transformed into an incoherent light beam having a substantially uniform spatial intensity distribution by homogenizing the laser beam with a light tunnel (a transparent light passageway having flat internally reflective side surfaces). It has been determined that when the cross-section of the tunnel is a polygon (as preferred) and the sides of the tunnel are all parallel to the axis of the tunnel (as preferred), the laser light at the exit of the light tunnel (or alternatively at any image plane with respect thereto) will have a substantially uniform intensity distribution and will be incoherent only when the aspect ratio of the tunnel (length divided by width) equals or exceeds the contangent of the input beam divergence angle .theta. and whenW.sub.min =L.sub.coh (R+(1+R.sup.2).sup.1/2)>2RL.sub.coh,where W.sub.min is the minimum required width for the light tunnel, L.sub.
