Abstract: An example of a field-effect transistor includes a source region, a drain region, a plurality of channel regions, and a gate region. The channel region includes a first and second semiconductor layers. A material of the first semiconductor layer includes silicon germanium, and a material of the second semiconductor layer includes germanium. The gate region wraps the plurality of channel regions and fills a gap between the plurality of channel regions. The first semiconductor layer has a top surface and a bottom surface that are perpendicular to a stacking direction of the plurality of channel regions, and a side surface that is parallel to the stacking direction of the plurality of channel regions. The second semiconductor layer is disposed on the top surface, the bottom surface, and the side surface of the first semiconductor layer.

Abstract: This application discloses an Ethernet coding method and apparatus, to adapt to a scenario in which a higher transmission bit error rate is caused by a high bandwidth. The method includes: a transmit end encodes first to-be-encoded information by using a first forward error correction (FEC) codeword, to obtain first encoded data, where the first forward error correction FEC codeword is a Reed-Solomon forward error correction (RS-FEC) codeword; and the transmit end encodes the first encoded data by using a second FEC codeword, to obtain second encoded data, where a code length N and an information bit length K of the second FEC codeword satisfy the following formula:




M1
∗

N
K

≤
M2,




where M1 is a throughput of the first encoded data, and M2 is a throughput of the second encoded data.
