  • Publication number: 20240429093
    Abstract: A method for fabricating a semiconductor device includes the steps of first defining a scribe line on a front side of a wafer, in which the wafer includes an inter-metal dielectric (IMD) layer disposed on a substrate and an alternating stack disposed on the IMD layer. Next, part of the alternating stack is removed to form a trench on the front side of the wafer, a dielectric layer is formed in the trench, and then a dicing process is performed along the scribe line from a back side of the wafer to divide the wafer into chips.
