A Deposition and Etch Technique to Lower Resistance of Semiconductor Metal Lines

Introduction Cu’s resistivity depends on its crystal structure, void volume, grain boundaries and material interface mismatch, which becomes more significant at smaller scales.  The formation of Cu wires is traditionally […]

Using Process Modeling to Enhance Device Uniformity during Self-Aligned Quadruple Patterning

Despite the growing interest in EUV lithography, self-aligned quadruple patterning (SAQP) still holds many technical advantages in pattern consistency, simplicity, and cost.  This is particularly true for very simple and […]

Accelerating the Development of Dry Etch Processes during Feature Dependent Etch

In dry etching, the trajectory of accelerated ions is non-uniform and non-vertical, due to collisions with gas molecules and other random thermal effects (Figure 1). This has an impact on […]
