Highly moisture-sensitive electronic device element and method for fabrication utilizing vent holes or gaps

A highly moisture-sensitive electronic device element having highly moisture-sensitive electronic devices comprising:

• a) a substrate containing two or more moisture-sensitive electronic devices;
• b) an encapsulation enclosure encapsulating all of the highly moisture-sensitive electronic devices on said substrate;
• c) sealing material positioned between said substrate and said encapsulation enclosure to form a complete seal between said substrate and said encapsulation enclosure and a space around each moisture-sensitive electronic device or around groups of moisture-sensitive electronic devices wherein the sealing material is organic material, inorganic material, or combinations thereof that is melted and cooled or reaction cured and wherein the reaction curing includes reactions resulting from heat, radiation, mixing of two or more components, exposure to ambient moisture, removal of ambient oxygen, or combinations thereof;
• d) water absorbing material positioned between said substrate and said encapsulation enclosure and within the space defined by said sealing material;
• and
• e) wherein the substrate or encapsulation enclosure, or both, contain vent holes and vent hole seal material in the vent holes.

A highly moisture-sensitive electronic device element having highly moisture-sensitive electronic devices comprising:

• a) a substrate containing two or more moisture-sensitive electronic devices that have been coated with a temporary moisture protection layer;
• b) an encapsulation enclosure encapsulating all of the highly moisture-sensitive electronic devices on said substrate;
• c) sealing material positioned between said substrate and said encapsulation enclosure to form a complete seal between said substrate and said encapsulation enclosure around each moisture-sensitive electronic device or around groups of moisture-sensitive electronic devices;
• and
• d) wherein the substrate or encapsulation enclosure, or both, contain vent holes and vent hole seal material in the vent holes.
