摘要:
To provide a method for producing a ceramic porous material which has a high strength, though it has a high porosity, and which is excellent in permeability without dust generation. In a ceramic porous material having a three-dimensional mesh-like skeleton structure with a large number of substantially spherical adjacent cells communicating with each other via communication holes, the crystal particle size at the rim of each communication hole in the skeleton structure is provided substantially equal to the crystal particle size in the other parts.
摘要:
A method for manufacturing a strained silicon wafer, having steps of a first step of preparing a single crystal silicon substrate, a second step of forming a graded SiGe layer on the substrate, the graded SiGe layer having a first Ge composition ratio increased stepwisely from 5 to 60% at atomic ratio, a third step of forming a SiGe constant composition layer on the graded SiGe layer, the SiGe constant composition layer having a Ge composition ratio substantially equal to the Ge composition ratio on a surface of the-graded SiGe layer and a fourth step of forming a strained Si layer on the SiGe constant composition layer. The second through fourth steps are performed under the reduced pressure atmosphere while the single crystal silicon substrate is rotated in a circumferential direction at a rate from 300 rpm to 1500 rpm.
