摘要: A device, apparatus and method for trapping metal ions detecting ion contamination in a solution provide semiconductor device formed on substrate including an N-well over P-type at least contact portion of the electrical with solution. When is optically illuminated, P/N junction as result photovoltaic phenomena. Metal from migrate to area due voltage created junction. The includes conductive structure features separated by gap therefore initially electrically open state. area, they precipitate, partially bridging creating conductance through structure. may be measured determine amount contamination.
