摘要： A method for forming a resist protect layer on a semiconductor substrate includes the following steps. An isolation structure is formed on the semiconductor substrate. An original nitride layer having a substantial etch selectivity to the isolation structure is formed over the semiconductor substrate. A photoresist mask is formed for partially covering the original nitride layer. A wet etching is performed to remove the original nitride layer uncovered by the photoresist mask in such a way without causing substantial damage to the isolation structure. As such, the original nitride layer covered by the photoresist mask constitutes the resist protect layer.

摘要： A method of defining a conductive gate structure for a MOSFET device wherein the etch rate selectivity of the conductive gate material to an underlying insulator layer is optimized, has been developed. After formation of a nitrided silicon dioxide layer, to be used as for the MOSFET gate insulator layer, a high temperature hydrogen anneal procedure is performed. The high temperature anneal procedure replaces nitrogen components in a top portion of the nitrided silicon dioxide gate insulator layer with hydrogen components. The etch rate of the hydrogen annealed layer in specific dry etch ambients is now decreased when compared to the non-hydrogen annealed nitrided silicon dioxide counterpart. Thus the etch rate selectivity of conductive gate material to underlying gate insulator material is increased when employing the slower etching hydrogen annealed nitrided silicon dioxide layer.
摘要翻译：已经开发了限定用于MOSFET器件的导电栅极结构的方法，其中导电栅极材料对下面的绝缘体层的蚀刻速率选择性被优化。在形成用于MOSFET栅极绝缘体层的氮化二氧化硅层之后，进行高温氢退火处理。高温退火程序用氢组分替代氮化二氧化硅栅极绝缘体层的顶部中的氮组分。当与非氢退火氮化二氧化硅对应物相比时，特定干蚀刻环境中的氢退火层的蚀刻速率现在降低。因此，当采用较慢的蚀刻氢退火氮化二氧化硅层时，导电栅极材料对底层栅极绝缘体材料的蚀刻速率选择性增加。

摘要： A new and improved liner modification method for a liner oxide layer in an STI trench is disclosed. According to the method, an STI trench is etched in a substrate and a liner oxide layer is formed on the trench surfaces by oxidation techniques. The method further includes pre-treatment of the trench surfaces using a nitrogen-containing gas prior to formation of the liner oxide layer, post-formation nitridation of the liner oxide layer, or both pre-treatment of the trench surfaces and post-formation nitridation of the liner oxide layer. The liner modification method of the present invention optimizes the inverse narrow width effect (INWE) and gate oxide integrity (GOI) of STI structures and prevents diffusion of dopant into the liner oxide layer during subsequent processing.
