Abstract: There is provided a marker selection program for selecting a marker for use in genetic diagnosis. In the program, analysis is carried out by using at least two specimen databases which respectively store data of specimens belonging different populations. By carrying out analysis without integrating all specimen data into single population, information on a minority population can be surely reflected to a gene search. Since the characteristics of each population can be reflected, high-accuracy diagnosing functions can be obtained, providing a practical diagnosing system.

Abstract: A semiconductor device comprises a semiconductor substrate, a first semiconductor layer under compressive strain formed on the semiconductor substrate, a p-type MISFET (Metal Insulator Semiconductor Field Effect Transistor) formed in a predetermined region of the first semiconductor layer, a second semiconductor layer in a lattice-relaxation condition formed on the first semiconductor layer in a region other than the predetermined region with an insulating film lying therebetween, wherein the insulating film has an opening and the first and second semiconductor layers are connected through the opening, a third semiconductor layer under tensile strain formed on the second semiconductor layer, and an n-type MISFET (Metal Insulator Semiconductor Field Effect Transistor) formed in the third semiconductor layer.
