METHODS OF DEPOSITING LINER LAYERS OF THROUGH GLASS VIA
Implementations of the present disclosure generally relate to liner layers and methods of forming liner layers for through glass vias. In one or more implementations, a liner layer is deposited on a glass substrate having a plurality of vias disposed through the glass substrate. The method includes depositing an adhesion layer onto and in a via of the plurality of vias to form the adhesion layer, the adhesion layer having a thickness of about 100 Angstroms to about 550 Angstroms, a tensile stress of about 30 MPa to about 80 MPa, and a Young's modulus of about 115 GPa to about 200 GPa and depositing a second layer onto the adhesion layer, the second layer having a thickness of about 2,000 Angstroms to about 60,000 Angstroms, a compressive stress greater than about 50 MPa, and a Young's modulus of about 35 GPa to about 70 GPa.
