In a fabrication process of a semiconductor integrated circuit device, upon effecting connection of an interconnection made of aluminum or aluminum alloy and another interconnection made of Cu or Cu alloy, a barrier conductor film or plug is disposed at the joint portion between these interconnections. In an embodiment, user input related to at least a first search criterion and a second search criterion is received at a portable playback device. Also, the device: monitors for a current setting value for the characteristic; and detects whether the current setting value is above or below the quality threshold.
