Publication number: 20230068091Abstract: In a method for fabricating a semiconductor device, a stack of alternating insulating layers and sacrificial layers are formed over a substrate. A staircase having a plurality of steps are formed in the stack, where each of the plurality of steps has a tread and a riser and further includes a respective pair of the insulating layer and the sacrificial layer over the insulating layer of the respective step. A dielectric layer is formed along the treads and risers of the plurality of steps. The dielectric layer is doped with one or a combination of carbon, phosphorous, boron, arsenic, and oxygen. The sacrificial layers are further replaced with a conductive material to form word line layers that are arranged between the insulating layers. A plurality of word line contacts are formed to extend from the word line layers of the plurality of steps, and further extend through the dielectric layer.Type: ApplicationFiled: October 18, 2021Publication date: March 2, 2023Applicant: Yangtze Memory Technologies Co., Ltd.Inventors: Xiongyu WANG, Yi ZHOU, Li ZHANG, XinSheng WANG, Hsing-An LO, GaoSheng ZHANG, YuPing XIA, Fei XIE
