Semiconductor device and data transmission method

The invention relates to the technical field of semiconductors, and provides a semiconductor device and a data transmission method. The semiconductor device comprises a first chip; a second chip; a photonic integrated circuit chip; a first plurality of electrical signal transmission lines configured to transmit an electrical signal of the first chip to the second chip; the second electric signal transmission line is configured to transmit an electric signal of a second chip to the photon integrated circuit chip, and the second chip is configured to convert a plurality of electric signals transmitted by the first group of the plurality of electric signal transmission lines into electric signals transmitted to the second electric signal transmission line and transmit the electric signals to the photon integrated circuit chip. Wherein each of the first plurality of electrical signal transmission lines has a lower data transmission rate than the second electrical signal transmission line. 本发明涉及半导体技术领域，其提供了半导体装置及数
