摘要
A field-effect semiconductor device having a channel region formed of two superimposed semiconductor layers, each layer being of a different type semiconductor. As between these two kinds of semiconductors, both the electron affinity and the sum of the electron affinity and the energy gap of one semiconductor is larger than the electron affinity and the sum of the electron affinity and the energy gap of the other semiconductor. This relationship is obtained by forming one of the semiconductor layers of Group III-V compound semiconductor and the other of Group IV semiconductor. The fabrication of the field-effect semiconductor device of this invention into monolithic integrated circuits is also disclosed.
