A surface acoustic wave device includes a piezoelectric substrate and interdigital electrode portions disposed on the piezoelectric substrate. The nonvolatile memory includes a substrate, a bottom electrode deposited on the substrate, a resistor layer deposited on the bottom electrode, and a top electrode on the resistor layer. The layer with the nitrogen-containing heterocycle derivative contained therein has a thickness greater than a hole supply layer arranged between the anode and the light-emitting layer. The low voltage connection points are capable of accepting standard jacks for broadband cable, direct TV, surround sound cabling, or phone systems. At this time, the crystallinity is improved.
