A semiconductor device according to an aspect of the present invention includes a semiconductor layer, an insulating film formed on the surface of the semiconductor layer, a first insulator embedded in the semiconductor layer with a thickness larger than the thickness of the insulating film, and a resistive element formed on the first insulator. The invention thus relates to the plants, seeds and tissue cultures of the variety CH006557, and to methods for producing a corn plant produced by crossing a corn plant of variety CH006557 with itself or with another corn plant, such as a plant of another variety. During the live, in-person auction, a bid is be accepted from an online bidder in the online environment that reflects the online bidder’s bid price for the item. Furthermore, it is possible to enhance device characteristics by decreasing gate induced drain leakage currents and improving a capability of driving currents.
