Abstract: Methods for reducing electron beam induced damage on semiconductor substrates employ compositions such as small chain organic solvents and non-neutral pH solutions to reduce or eliminate charge imbalances on semiconductor substrates caused by electron beam inspection of the semiconductor substrates. Damage to semiconductor substrates by electron beam inspection processes may also be reduced by generating or otherwise forming passivation films on a semiconductor substrate following electron beam inspection.

Abstract: A method that may be applied to imaging and identifying defects and contamination on the surface of an integrated circuit is described. An energetic beam, such as an electron beam, may be directed at a selected IC location having a layer of a solid, fluid, or gaseous reactive material formed over the surface. The energetic beam disassociates the reactive material in the region into chemical radicals that either chemically etch the surface preferentially, or deposit a thin layer of a conductive material over the local area around the energetic beam. The surface may be examined as various layers are selectively etched to decorate defects and/or as various layers are locally deposited in the area around the energetic beam. SEM imaging and other analytic methods may be used to identify the problem more easily.

Abstract: An improved isolation structure for use in an integrated circuit and a method for making the same is disclosed. In a preferred embodiment, an silicon dioxide, polysilicon, silicon dioxide stack is formed on a crystalline silicon substrate. The active areas are etched to expose the substrate, and sidewall oxides are formed on the resulting stacks to define the isolation structures, which in a preferred embodiment constitute dielectric boxes containing the polysilicon in their centers. Epitaxial silicon is grown on the exposed areas of substrate so that it is substantially as thick as the isolation structure, and these grown areas define the active areas of the substrate upon which electrical structures such as transistors can be formed. While the dielectric box provides isolation, further isolation can be provided by placing a contact to the polysilicon within the box and by providing a bias voltage to the polysilicon.
