    • A method for forming a semiconductor device is disclosed. A method for forming a semiconductor device includes forming a first sacrificial hard mask layer over a semiconductor substrate including an etch layer, forming a first spacer over the first sacrificial hard mask layer, forming a first sacrificial hard mask pattern by etching the first sacrificial hard mask layer using the first spacer as an etch mask, forming a second spacer at both sidewalls of the first sacrificial hard mask pattern, partially isolating the second spacer, and forming a pad pattern over the second spacer. As a result, a line-and-space pattern such as a control gate of the NAND flash memory and a pad portion coupled to a drain contact in an X-decoder of a peripheral circuit region can be easily implemented.
    • 公开了一种用于形成半导体器件的方法。 一种形成半导体器件的方法包括在包括蚀刻层的半导体衬底上形成第一牺牲硬掩模层,在第一牺牲硬掩模层上形成第一间隔物,通过蚀刻第一牺牲硬掩模形成第一牺牲硬掩模图案 层,使用第一间隔物作为蚀刻掩模,在第一牺牲硬掩模图案的两个侧壁处形成第二间隔物,部分地隔离第二间隔物,以及在第二间隔物上形成焊盘图案。 结果,可以容易地实现诸如NAND快闪存储器的控制栅极和耦合到外围电路区域的X解码器中的漏极触点的焊盘部分的线间距图案。

    • A method for forming a pattern of a semiconductor device is provided. Specifically, in a method for manufacturing a NAND flash memory device using a spacer patterning process, a dummy pattern, which is not used in an actual device operation, is additionally formed in a peripheral circuit region when a photoresist pattern for forming a string pattern is formed in a cell region. As a result, the edge photoresist pattern is prevented from being bent, and a critical dimension difference between the center region and the edge region of the photoresist pattern is not generated, thereby improving a margin of DOF to obtain a reliable semiconductor device.
    • 提供了形成半导体器件的图案的方法。 具体地,在使用间隔物图案化工艺的NAND闪速存储器件的制造方法中,当用于形成线图案的光致抗蚀剂图案是(...)形状时,在外围电路区域中另外形成不用于实际器件操作的虚拟图案 形成在细胞区域中。 结果,防止边缘光致抗蚀剂图案弯曲,并且不产生光致抗蚀剂图案的中心区域和边缘区域之间的临界尺寸差异,从而提高DOF的余量以获得可靠的半导体器件。
