The semiconductor device is in the form of a semiconductor chip formed as a recording head of an ink-jet printer or in the form of a semiconductor wafer having at least two semiconductor chips. In one embodiment, a method comprises playing back a set of recorded transactions on a client, monitoring selected performance-related parameters at the client, and transmitting monitored data to the server for analysis or for viewing by a system administrator. The second layer and the forth layer are etched, thereby patterning the second and fourth layer to form the second laterally confined structure.
