摘要： A method for fabricating STI for semiconductor device. The method includes the following steps. A trench is formed on the semiconductor substrate, a liner oxide is formed on the bottom and sidewall of the trench, and then a liner nitride is formed on the liner oxide. The first oxide layer is deposited in the trench by high density plasma chemical vapor deposition. The first oxide layer is spray-etched to a predetermined depth, wherein the recipe of the spray etching solution is HF/H2SO4=0.3˜0.4. A second oxide layer is deposited to fill the trench by high density plasma chemical vapor deposition to form a shallow trench isolation structure.

摘要： A method and an apparatus for drying a semiconductor wafer. The semiconductor wafer is first dipped in a liquid with a volatility higher than water and which is miscible with water. The dipped semiconductor wafer is then delivered in an IPA dryer to carry out the drying process. The drying process includes evaporating isopropyl alcohol to obtain a vapor and condensing the IPA vapor on the surface of the semiconductor wafer. The IPA is heated and vaporized by a hot plate disposed at the bottom of the IPA dryer. The condenser is mounted on the inner peripheral surface of the IPA dryer and surrounds the semiconductor wafer, which is supported by a holder.
