Trench isolation stress relief
In a microelectronic device formed on a substrate 12, a pair of trenches 30, 36 branch at their intersection to provide branches 31-34 surrounding a sacrificial island 42. Sacrificial island 42 may comprise substrate material or other material or a void for absorbing the axial stresses propagated al...

| Zusammenfassung: | In a microelectronic device formed on a substrate 12, a pair of trenches 30, 36 branch at their intersection to provide branches 31-34 surrounding a sacrificial island 42. Sacrificial island 42 may comprise substrate material or other material or a void for absorbing the axial stresses propagated along the lengths of trenches 30, 36. |
