Abstract:
1. A method for fabricating multiple insulator layers, alternating a develop mechanism of insulator layers via strain field generated by stress, the method comprises: providing a P-type or N-type fabricating material; forming a buffer layer on the P-type or N-type fabricating material; forming a quantum dot layer comprising crystal points on a buffer layer, the crystal points being shaped as an island; depositing a intermediate layer, the intermediate layer being coplanar, the crystal points having different strain field; forming continuously at least one quantum dot layer comprising crystal points, then depositing at least one intermediate layer on the quantum dot layer; depositing a silicon coverage layer on the quantum dot layer comprising the crystal points, the silicon coverage layer being coplanar; wherein multiple insulator layers are deposited on the silicon coverage layer via different tensile stress generated.
