3D NAND, or vertical NAND, with its higher density and lower cost per bit, has been a driving force in the popularity of solid state drives (SSD) thanks to the innovation and continued investment from both manufacturers and suppliers. 9x-layer NAND devices are now commonly available in the market and 1xx layer NAND devices have been in mass production for a year.

In this webinar, we present a comparison of 9x-layer 3D NAND devices from major manufacturers: Samsung, KIOXIA / Western Digital, Intel / Micron and SK hynix. The process sequence is discussed, with emphasis on the word line pad (WLP), also commonly known as staircase. The usage of lithography masks for WLP is further considered, with an in-depth discussion of one device, to provide a clearer understanding of the WLP formation.
