We discuss the enhancement effects of the electron-hole BCS order due to the effective-mass anisotropy in highly photoexcited semiconductors. The present study provides us with a new possibility to experimentally observe a macroscopic quantum state by applying the uniaxial stress to semiconducting materials with high density electrons and holes. It is quantitatively shown that this enhancement due to the stress induced mass anisotropy can exceed the reduction of the order arising from the temperature effect and to from the difference in valence- and conduction-band structures.
