3. RETENTION AND ENDURANCE CYCLING Figure 3a shows small inverted dots (diameter 28 nm on average) imaged by PFM within an hour after they are first written. The dots are shown with brighter contrast. 3 mm/s was used to write the dots array with the writing data rate ~41 kbps. Figure 3b shows the PFM image of the dots 68 h after Figure 3a was taken. The time comparison of the dots show good retention under the room ambient condition over a period of few days tracked. A temperature accelerated retention test on similar type of dots confirmed that the small dots can stay with over a year of retention.

Finally, the tips are coated with the Pt layer, which is used also to form the trace. The coating increases the hardness of the tips minimizing tip wearing. The process allows for sharp tips with a top diameter less then 50 nm after Pt coating. A Ni/Au pattern for bonding the CMOS/cantilever wafer to the micro-mover wafer is formed with help of electroplating at the end of the process. Due to excellent stress control of the structural layers, minimal deflection of the cantilever structures is observed after HF release.

Instead electro-optical testing can be used: large groups of cantilevers can be electrically actuated and pattern recognition technique can be used to evaluate response of the cantilever array. 4. Electronics and system aspects A Nanochip device provides storage at the system level by delivering data through an error free interface and eliminates the need to manage device inherent idiosyncrasies such as mapping defects, data block wear leveling, and block erase management. In comparison, NAND flash memory is a component used to build storage devices leaving the task of components management to system designers and integrators.
