摘要:
A method and a device made according to the method. The method comprises providing a substrate including a first material, and providing a fin including a second material, the fin being disposed on the substrate and having a device active portion, the first material and the second material presenting a lattice mismatch between respective crystalline structures thereof. Providing the fin includes providing a biaxially strained film including the second material on the substrate; and removing parts of the biaxially strained film to form a substantially uniaxially strained fin therefrom.
