Post deposition adjustment of chalcogenide composition in chalcogenide containing semiconductors
The concentration of a constituent within a chalcogenide film used to form a chalcogenide containing semiconductor may be adjusted post deposition by reacting the chalcogenide film with a material in contact with the chalcogenide film. For example, a chalcogenide film containing tellurium may be coa...

| Zusammenfassung: | The concentration of a constituent within a chalcogenide film used to form a chalcogenide containing semiconductor may be adjusted post deposition by reacting the chalcogenide film with a material in contact with the chalcogenide film. For example, a chalcogenide film containing tellurium may be coated with a titanium layer. Upon the application of heat, the titanium may react with the tellurium to a controlled extent to reduce the concentration of tellurium in the chalcogenide film. |
