Table 1. Data summary of tungsten/silicon oxide comb structures: physical dimensions, inspected areas, number of cells inspected, % population of cells with 10° > ϕ > −10° and 20° > ϕ > −20° of the metal line axis. The culture media initial cell concentration used was 2 × 10⁵ cells/mL. Data spreads correspond to one standard deviation.
