ABSTRACT
A silicon-on-silicon dioxide structure (silicon-on-insulator) produced by combined ‘‘van der Waals’’ bonding and laser fusing has been studied by cross-sectional transmission electron microscopy. Areas in the silicon corresponding to the regions which are locally melted by the laser beam were found to contain a high density of dislocations after fusing. The radius and depth of these defect areas, as observed in the microscope, are compared with a simple analytical model of the laser-induced melting process.

    We describe a process for the formation of silicon-on-insulator structures by selective anodization of a buried p-type layer to form porous silicon which is then oxidized. A buried n-type layer ensures that the flow of the anodizing current, and hence the formation of the porous silicon layer,...
