概要（Overview）

The 2300 Syndion, which also employs TCP technology, addresses 3-D IC through-silicon via (TSV) etch applications. TSVs provide the interconnects for die-to-die and wafer-to-wafer stacking, eliminating wire bonding to increase device packing density (smaller form factor) and improve performance (higher process speed and lower power requirements). Important for TSV applications, the Syndion’s TCP-based technology enables sequential processing the same chamber while ensuring etch rate uniformity and profile symmetry to prevent tilting. The technology also supports clean mode operation and provides bias voltage control for process repeatability.
