Abstract(in English) | A ferro-electric random access memory or FeRAM is a non-volatile memory combining both ROM and RAM advantages. To promote making of a high density FeRAM, the defective bit evaluation technology of the device is needed. We constructed a new evaluation system, which was able to measure the electric characteristics of a single bit cell capacitor. In the system, a top electrode of a capacitor was contacted electrically by the cantilever of a scanning probe microscope (SPM). An independent manual micro-probe was set-up adjacent to the scanner of SPM to contact a bottom electrode. A pad for a bottom electrode was made with focused ion beam (FIB) equipment. The size of the contact pad was optimized to minimize the parasitic capacitance. In order to measure the electric characteristics of a cell capacitor with a small contact hole, we decreased the depth of the contact hole by filling it with tungsten using FIB. As a result, the measurement of the single bit capacitor became possible, and it has promoted failure analysis of actual devices. |
