An example method includes providing a working stack having a first substrate layer, a second substrate layer, and a radiation absorbing material disposed between the first substrate layer and the second substrate layer. The working stack includes a cavity with the specified liquid therein. A bonding interface is defined between the radiation absorbing material and at least one of the first substrate layer or the second substrate layer. The bonding interface has a film of the specified liquid. The method also includes directing radiation onto the bonding interface to form a peripheral seal. The peripheral seal is separated from the outer region of the cavity and the bonding interface. The method also includes directing the radiation onto the outer region of the bonding interface to secure the first and second substrate layers together. The peripheral seal prevents air bubbles from entering the cavity from the outer region when the radiation is directed onto the outer region. |
