The VSAFETs with self-aligned high- k metal gates (HKMGs) were fabricated with epitaxy of Si/SiGe/Si sandwich structure, an isotropic quasi-atomic-layer-etch (qALE) process, and gate replacement ...

Drywall anchors are a handy solution in these cases. Simply drill a hole and insert an anchor, and its firm grip on the drywall provides a strong base for hanging heavier items than the drywall alone ...
