A plasma display panel including address electrodes extending in a first direction, and scanning and sustain electrodes extending in a second direction, the electrodes corresponding to discharge cells. A third semiconductor film is formed over the entire surface of the semiconductor substrate so as to fill in the step. The method also reads each memory location to verify that the memory location is unprogrammed and activates the programming circuitry for each memory location, which applies a test current to the programming circuitry. By breaking the anneal into two steps, smaller semiconductor nanowires at a tight pitch survive the process and yield. In so doing, the machine check unit deactivates the hold commands in each function module by means of the control codes.
