Abstract
A semiconductor device is employable for a compact and light-weight sensor system that is free of the need for battery replacement. The semiconductor device has a sensor chip (SCHIP) comprising sensors (TD, AS, PD, GS), an A/D conversion circuit (AD), a microprocessor (CPU), a memory (MEM), a transmission circuit (RF), and a power generation circuit (CM). The sensors, the A/D conversion circuit, the microprocessor, the memory, and the transmission circuit are formed on one side (SIDE) of a substrate, while the power generation unit is formed on the other side (SIDE) of the substrate.
