  • Method and system for using TMAH for staining copper silicon on insulator semiconductor device cross sections
    Patent number: 6770512
    Abstract: A method and system for performing failure analysis on a silicon on insulator (SOI) semiconductor device is disclosed. The SOI device includes a plurality of conductive structures in a silicon region. The silicon resides on a box insulator, which resides on a silicon substrate. The method and system include providing a cross-section of the SOI semiconductor device. The cross-section of the SOI semiconductor device includes a portion of the plurality of conductive structures. The method and system also include staining the cross-section of the SOI semiconductor device using a stain. The stain etches the silicon region in the SOI semiconductor device without etching a remaining portion of the SOI semiconductor device not composed of silicon.
