What is Dynamic AGE-ing®?

The three proprietary functions of the Dynamic AGE-ing® method enableSiC wafer quality ​improvement and surface planarization control.

  1. 1DA-Etching:Removal of subsurface damage layers caused by wafer fabrication​

  2. 2DA-Growth: Formation of a BPD/SF-free epitaxial layer​

  3. 3DA-Annealing:Surface planarization of SiC wafers​

BPD = basal plane dislocation
IGSF = In-Grown stacking fault

When DA-Etching and DA-Growth are sufficiently applied,processing-induced damage is removed,and BPD and IGSF densities in the DA-grown layer can be reduced to near-zero levels.

TED = Threading edge dislocation
SSD = Subsurface damage

By applying DA-Annealing to as-sliced wafers immediately after ingot cutting,​CMP-equivalent planarization can be achieved.
