Lower Vertical Grid Barrier Deposition - 40nm

TiN or TaN forms a dense barrier that raises diffusion activation energies and lowers diffusion coefficients, ensuring structural integrity during subsequent processes [P3].

After the trench structure is defined by the preceding Oxide Grid Seal Layer Etch and cleaning steps, the Lower Vertical Grid …
