    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 for forming a microelectronic product and the microelectronic product resulting from the method both employ a bilayer gate electrode. The bilayer gate electrode employs: (1) a first layer formed of a random oriented polycrystalline silicon material; and (2) a second layer laminated to the first layer and formed of a columnar oriented polycrystalline silicon material. The gate electrode provides enhanced performance to a semiconductor device within which it is formed.

    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.
