    • A method of fabricating an integrated circuit device comprises etching a trench in a substrate and forming a dynamic random access memory (DRAM) cell having a storage capacitor at a lower end and an overlying vertical metal oxide semiconductor field effect transistor (MOSFET) comprising a gate conductor and a boron-doped channel. The method includes forming trenches adjacent the DRAM cell and a silicon-oxy-nitride isolation liner on either side of the DRAM cell, adjacent the gate conductor. Isolation regions are then formed in the trenches on either side of the DRAM cell. Thereafter, the DRAM cell, including the boron-containing channel region adjacent the gate conductor, is subjected to elevated temperatures by thermal processing, for example, forming a support device on the substrate adjacent the isolation regions. The nitride-containing isolation liner reduces segregation of the boron in the channel region, as compared to an essentially nitrogen-free oxide-containing isolation liner.
    • 一种制造集成电路器件的方法包括蚀刻衬底中的沟槽并形成具有位于下端的存储电容器的动态随机存取存储器(DRAM)单元和覆盖的垂直金属氧化物半导体场效应晶体管(MOSFET),其包括栅极 导体和掺硼通道。 该方法包括在DRAM单元附近形成沟槽和在DRAM单元的任一侧上与栅极导体相邻的硅 - 氮氧化物隔离衬垫。 然后在DRAM单元的两侧的沟槽中形成隔离区。 此后,包括与栅极导体相邻的含硼沟道区域的DRAM单元通过热处理受到升高的温度,例如,在邻近隔离区域的衬底上形成支撑器件。 与基本上不含氮氧化物的隔离衬垫相比,含氮化物的隔离衬垫减少了沟道区域中的硼的偏析。
