    • A method and the resulting product for isolating lightly doped silicon islands from each other and from a common substrate. The substrate is covered with a first heavily doped epi layer. The first layer is covered with a lightly doped second epi layer. A pair of spaced deep trenches are provided which extend from the top surface of the second layer, through the first layer and into the substrate. The interior walls of the trenches are lined with oxide. A pair of heavily doped reach-through diffusions extending from said top surface to the first layer is oriented perpendicularly to the deep trenches and fully extends between the trenches. The heavily doped reach-through diffusions and the contiguous first layer are removed by a single anisotropic etching step to yield silicon islands isolated by air except where the islands contact the oxide-lined deep trenches. The air isolation preferably is partially replaced with other dielectric material.

    • An oxynitride material is used to form shallow trench isolation regions in an integrated circuit structure. The oxynitride may be used for both the trench liner and trench fill material. The oxynitride liner is formed by nitriding an initially formed oxide trench liner. The oxynitride trench fill material is formed by directly depositing a high density plasma (HDP) oxide mixture of SiH4 and O2 and adding a controlled amount of NH3 to the plasma mixture. The resultant oxynitride structure is much more resistant to trench fill erosion by wet etch, for example, yet results in minimal stress to the surrounding silicon. To further reduce stress, the nitrogen concentration may be varied by varying the proportion of O2 to NH3 in the plasma mixture so that the nitrogen concentration is maximum at the top of the fill material.
    • 氧氮化物材料用于在集成电路结构中形成浅沟槽隔离区。 氧氮化物可以用于沟槽衬垫和沟槽填充材料。 氧氮化物衬垫通过氮化最初形成的氧化物沟槽衬垫而形成。 氧氮化物沟槽填充材料通过直接沉积SiH 4和O 2的高密度等离子体(HDP)氧化物混合物并且将等量的NH 3加入到等离子体混合物中而形成。 所得到的氮氧化物结构例如通过湿法蚀刻对沟槽填充侵蚀的抵抗性更高,但是对周围硅的应力最小。 为了进一步减少应力,可以通过改变等离子体混合物中的O 2与NH 3的比例来改变氮浓度,从而在填充材料的顶部的氮浓度最大。
