    • An integrated circuit device and a manufacturing method thereof are provided to improve reliability of a device by using a dual stress formation layer for improving mobility of a charge carrier. A first active area(108) and a second active area(109) are defined. A first transistor(140a) is formed on the first active area. A second transistor(140b) is formed on the second active area. A substrate(105) in which an element separation region is formed is provided between the first active area and the second active area. A first stress layer(160a) forming a first stress for improving mobility of a second charge carrier is formed on the substrate so as to cover the first transistor. A second stress layer(160b) forming a second stress for improving mobility of a first charge carrier is formed on the substrate. The second stress layer is formed to be overlapped with the first stress layer on the element separation region. By polishing the substrate, a part of the second stress layer overlapped with the first stress layer is removed. The substrate is polished so that a border between the second stress layer and the first stress layer can have an upper side without a gap.

    • A method for fabricating a semiconductor device is provided to reduce the recess depth which is formed in forming an element isolation film by performing a curing ion injecting and a heat treatment. A high aspect ration trench(A,B) is formed by etching a semiconductor(100) which is exposed to the outside by a pad oxide film pattern and pad nitride film pattern by a certain depth. A liner film is formed by coating a thin nitride film on the whole surface of a formed structure, a trench is filled by depositing a gap fill oxide film on the formed structure. The oxide film for the gap fill is planarized by using the chemical mechanical polishing. A curing ion is injected into the oxide film for the gap fill, and the top of the oxide film for the gap fill is changed from an amorphous state into the re-crystallization state by performing the high temperature heat treatment. A core(124) is removed from the oxide for the gap fill through the curing ion injection process and high temperature heat treatment.
    • 提供一种制造半导体器件的方法,以通过进行固化离子注入和热处理来减少在形成元件隔离膜时形成的凹陷深度。 通过蚀刻通过衬垫氧化膜图案和衬垫氮化物膜图案一定深度暴露于外部的半导体(100)来形成高深度比例沟槽(A,B)。 通过在形成的结构的整个表面上涂覆薄的氮化物膜形成衬里膜,通过在形成的结构上沉积间隙填充氧化物膜来填充沟槽。 通过使用化学机械抛光将用于间隙填充的氧化膜平坦化。 将固化离子注入到用于间隙填充的氧化物膜中,并且通过进行高温热处理,用于间隙填充的氧化物膜的顶部从非晶态改变为再结晶状态。 通过固化离子注入过程和高温热处理,从氧化物中除去芯部(124)用于间隙填充。
