Abstract
A substrate bonding method comprises the following steps. Firstly, a first substrate and a second substrate are provided, wherein a surface of the first substrate is covered by a first Ag layer and a surface of the second substrate is covered by a second Ag layer and a metallic layer from bottom to top, wherein the metallic layer comprises a first Sn layer. Secondly, a bonding process is performed by aligning the first and second substrates followed by bringing the metallic layer into contact with the first Ag layer followed by applying a load while heating to a predetermined temperature in order to form Ag3Sn intermetallic compounds. Finally, cool down and remove the load to complete the bonding process.
