The invention discloses a method for fabricating strained silicon on insulator by phase change method, which adopts dense and smooth amorphous silicon deposition technology, low temperature bonding technology, irreversible phase change control of amorphous silicon to microcrystalline silicon, and microcrystals. The ingenious combination of silicon internal oxidation technology avoids the expensive silicon germanium epitaxy and chemical mechanical polishing process in the preparation of existing SSOI materials, and does not require the subsequent CMOS process modification after SGOI material fabrication, etc., to achieve a new The production of SSOI materials, while achieving the production cost goal of reducing SSOI.
Plus Size Dress also have so many different dresses for different tastes and different occasions! Hitting above the knee, these dresses tend to feel a little bit more like partywear. Midi length dresses hit around the knee and are perfect for easy casual dresses. Accessorize with sunglasses and your favorite sneakers for a laidback look. For a fancy alternative, go for a jumpsuit in a bold hue like scarlet or canary yellow to really command attention.
