A sheet feeder with a feed wheel assembly for conveying an end sheet from a stack of sheets. The feed wheel assembly has a rotatable engagement wheel positioned to contact the end sheet of the stack, and operable to separate and convey the end sheet from the stack; a horizontally extending first shaft on which the wheel is mounted, with the first shaft being angularly movable in a generally vertical direction; a horizontally extending second shaft positioned spaced apart from the first shaft, the second shaft being mounted in a substantially fixed planar orientation to a support frame; and a pair of laterally spaced-apart first and second arms extending between the first and second shafts. Each of the first and second arms has a first portion retaining the first shaft and a second portion longitudinally spaced from the first portion and pivotally connected to the second shaft. The first and second arms are independently-pivotally movable about the second shaft within at least a limited range to permit uninhibited angular movement of the first shaft in a generally vertical direction during operation.

A microfiche feeder 10 conveys isolated sheets of microfiche from a stack 30 to a collator 12, sorter, or other processing apparatus. The stack of microfiche is placed in a receiver. A drive wheel 34 contacts the lowest sheet of the stack 30 to increment the sheet forward by suction as the wheel revolves. Spaced separator rolls 44 and 46 adjacent the drive wheel 34 ensure that a single sheet of microfiche is incremented forward to drive rolls 52 and 54, which convey the sheet to other processing apparatus.

Disclosed herein is a method of making integrated circuits. In one embodiment the method includes forming tungsten plugs in a integrated circuit and forming electrically conductive interconnect lines after formation of the tungsten plugs, wherein at least one tungsten plug is electrically connected to at least one electrically conductive interconnect line. Separate from the formation of the tungsten plugs and electrically conductive interconnect lines, a gas is introduced into a liquid. At least one electrically conductive interconnect line is then contacted with the gas introduced liquid.
