Semiconductor device with antenna and light-emitting element

摘要

When a conductive layer occupying a large area is provided in a coiled antenna portion, it has been difficult to supply power stably. A memory circuit portion and a coiled antenna portion are disposed by being stacked together; therefore, it is possible to prevent a current from flowing through a conductive layer occupying a large area included in the memory circuit portion, and thus, power saving can be achieved. In addition, the memory circuit portion and the coiled antenna portion are disposed by being stacked together, and thus, it is possible to use a space efficiently. Therefore, downsizing can be realized.
