ABSTRACT
In this letter, we present techniques, utilizing dielectrophoresis and electrohydrodynamics, which can be used for assembling single-crystal silicon devices suspended in a solution onto a binding site on a heterogeneous substrate. Silicon resistors with gold/chromium layers located at the end of the resistors and silicon blocks without metal were fabricated on bonded and etched-backed silicon-on-insulator wafers and successfully released into deionized water. The devices were subsequently assembled on a different substrate at specific binding sites by dielectrophoretic and electrohydrodynamic forces with submicron precision. Current–voltage measurements of the assembled resistors exhibited low contact resistance after the solution was completely evaporated and the contacts were annealed. © 2003 American Institute of Physics.

    The strain in a porous Si layer formed by anodization of a crystalline p+-Si(100) wafer in a HF electrolyte was measured by double-crystal x-ray diffractometry. The perpendicular strain in the as-formed porous Si layer is ∼10-3. The parallel strain is not measurable (<10-4). Upon annealing...

    A conceptually simple experiment to measure silicon interstitial diffusivity is described. The structure uses a silicon wafer with buried layers deep in the bulk. Oxidation of the wafer surface generates interstitials that diffuse into the wafer and enhance the buried layer diffusion. The...
