摘要： A semiconductor device including first and second transistors is provided. The first transistor includes first and second regions each being arranged between corresponding one of diffusion regions and a channel region and having a lower concentration than the diffusion regions, and a first length of the first region is longer than a length of the second region. The second transistor includes third and fourth regions each being arranged between corresponding one of diffusion regions and a channel region and having a lower concentration than the diffusion regions, and a third length of the third region is longer than a length of the fourth region. A depth of the first region is equal to a depth of the third region, the third length is longer than the first length, and a higher voltage than the first transistor is applied to the second transistor.

摘要： A light emitting device in which a reflective film, a first electrode, an organic film including a light emitting layer, a second electrode, and an optical member are arranged in this order on a principal surface of a substrate and a bank configured to cover a peripheral portion of the first electrode is provided to define a light emitting region. The reflective film, the first electrode, the organic film, and the second electrode form a resonator structure configured to resonate, between the reflective film and the second electrode, light generated in the organic film. In the light emitting region, an upper surface of the reflective film is flatter than the first electrode. The resonator structure has a plurality of different optical path lengths.
