Method of manufacturing electronic device, electronic apparatus, and mobile apparatus
A method of manufacturing an electronic device including an electronic element, a base substrate, and a lid member, includes joining the lid member to the sealing part by application of an energy beam so that a plate thickness of the lid member may be larger in a part joined to the sealing part than in a part located inside of the part in a plan view along the thickness direction.
1. A method of manufacturing an electronic device comprising:
preparing an electronic element, a base substrate having a recessed part and including a sealing part on a peripheral edge of the recessed part, and a lid member including a base material layer and a brazing filler metal layer extending the length and width of the lid member;
placing the electronic element in a bottom part of the recessed part;
placing the lid member on the base substrate so that the sealing part and the brazing filler metal layer may overlap; and
joining the lid member to the sealing part by application of an energy beam so that a plate thickness of the base material layer and the brazing filler metal layer of the lid member is larger throughout a part joined to the sealing part than in a part located inside of the part in a plan view along the thickness direction.
2. The method of manufacturing an electronic device according to claim 1 , wherein the joining includes forming the part of the lid member joined to the sealing part in which the plate thickness of the lid member is smaller by movement of the brazing filler metal layer.
3. A method of manufacturing an electronic device comprising:
preparing an electronic element, a base substrate having a recessed part and including a sealing part on a peripheral edge of the recessed part, and a lid member including a base material layer and a brazing filler metal layer extending the length and width of the lid member;
placing the electronic element in a bottom part of the recessed part;
placing the lid member on the base substrate so that the sealing part and the brazing filler metal layer may overlap; and
joining the lid member to the sealing part by application of an energy beam so that a difference between a plate thickness of the lid member in a part joined to the sealing part and a plate thickness of the lid member in a part located inside of the part in a plan view along the thickness direction after the application of the energy beam is larger than a difference between a plate thickness of the lid member in a part joined to the sealing part and a plate thickness of the lid member in a part located inside of the part in a plan view along the thickness direction before the application of the energy beam.
4. The method of manufacturing an electronic device according to claim 1 , wherein the lid member is joined to the sealing part a difference between a plate thickness of the lid member in a part joined to the sealing part and a plate thickness of the lid member in a part located inside of the part in a plan view along the thickness direction after the application of the energy beam is larger than a difference between a plate thickness of the lid member in a part joined to the sealing part and a plate thickness of the lid member in a part located inside of the part in a plan view along the thickness direction before the application of the energy beam.
5. A method of manufacturing an electronic device comprising:
preparing an electronic element, a base substrate having a recessed part and including a sealing part on a peripheral edge of the recessed part, and a lid member including a base material layer and a brazing filler metal layer extending the length and width of the lid member;
placing the electronic element in a bottom part of the recessed part;
placing the lid member on the base substrate so that the sealing part and the brazing filler metal layer overlap; and
joining the lid member to the sealing part by application of an energy beam to create a region without the brazing filler metal layer.
