Glass sealing with transparent materials having transient absorption properties

A method of sealing a device comprising the steps of:

• forming a sealing layer over a surface of a first substrate;
• arranging a device to be sealed between the first substrate and a second substrate where the sealing layer is in contact with the second substrate to thereby form an interface between the first substrate, sealing layer and second substrate;
• locally heating the interface using laser radiation to cause a local increase in temperature at the interface and to melt the sealing layer at the interface;
• altering absorption characteristics of portions of the first substrate and second substrate adjacent the interface as a function of the local increase in temperature;
• melting the portions of the first substrate and second substrate as a function of the altered absorption characteristics;
• and
• sealing the device between the first and second substrates by the melted sealing layer and melted portions of the first and second substrates.

A sealed device comprising:

• a glass film formed over a surface of a first substrate;
• and
• a device protected between the first substrate and a second substrate wherein the glass film is in contact with the second substrate,
• wherein the device is hermetically sealed between the first and second substrates as a function of the composition of impurities in the first or second substrates and as a function of the composition of the glass film though a local heating of the glass film with laser radiation having a predetermined wavelength.
