PIT2SD to Mount Wafers for Thru-Wafer Etching

Dry etch­ing refers to the removal of mate­r­i­al, typ­i­cal­ly a masked pat­tern of semi­con­duc­tor mate­r­i­al, by expos­ing the mate­r­i­al to a bom­bard­ment of ions that dis­lodge por­tions of the mate­r­i­al from the exposed sur­face. Unlike with many of the wet chem­i­cal etchants used in wet etch­ing, the dry etch­ing process typ­i­cal­ly etch­es direc­tion­al­ly or anisotropically.

PIT2SD, a 2‑mil dou­ble-sided poly­imide tape is often used to mount wafers on a car­ri­er for through wafer etch­ing and it works very well.
