Abstract

See full text

A method of forming a semiconductor structure includes forming a multilayer lattice matched structure having an unstrained layer, a first strained layer, and a second strained layer formed between the unstrained and the first strained layer. A first opening in the multilayer structure is etched and a second strained fill material having a same material as the second strained layer is deposited. A second opening in the multilayer structure is etched and an unstrained fill material having a same material as the unstrained layer is deposited. A first strained fill material having a same material as the first strained layer is then deposited between the unstrained fill and the second strained fill. A second strained fin is formed from the deposited second strained fill material, a first strained fin is formed from the deposited first strained fill material, and an unstrained fin is formed from the deposited unstrained fill material.
