Module, electronic apparatus, moving object, and method of manufacturing module
View Patent ↗A module includes an insulating substrate having an upper surface as a principal surface, a lid member having an internal space with the insulating substrate, and bonded to the upper surface in a first surface, a device element housed in the internal space, a semiconductor element connected to a top surface, which forms the both sides of the lid member together with the first surface, using a resin adhesive, electrodes electrically connected to the device element, and disposed on an upper surface of the insulating substrate in an area other than the connection area with the lid member, and a projection section formed of the same member as the lid member on the upper surface in an area between the electrodes and the lid member in a plan view.
1. A module comprising:
a first base member;
a second base member having an internal space with the first base member, and bonded to a principal surface of the first base member;
a first functional element housed in the internal space;
a second functional element connected to a surface of the second base member on an opposite side to the internal space with a bonding member;
an electrode electrically connected to the first functional element, and disposed on the principal surface of the first base member in an area other than a connection area with the second base member; and
a projection section on only a single side of the second base member, formed of a same member as the second base member, and disposed on the principal surface in an area between the electrode and the second base member in a plan view,
wherein the second base member engages with the first base member to entirely cover the first functional element.
2. The module according to claim 1 , wherein
a distance between the projection section and the second base member on a tip side of the projection section is longer than a distance between the projection section and the second base member on the principal surface side.
3. The module according to claim 2 , wherein
the second base member has a slope as a side surface near to an area where the projection section is provided.
4. The module according to claim 1 , wherein
the second base member has a slope as a side surface near to an area where the projection section is provided.
5. The module according to claim 1 , wherein
the second functional element is connected so as to project from the surface of the second base member on the opposite side to the internal space toward the electrode.
6. The module according to claim 1 , wherein
the principal surface of the first base member is provided with a groove,
the first functional element and the electrode are electrically connected to each other with a wiring line disposed in the groove, and
the groove is filled with a sealing member disposed in a gap between the projection section and the second base member.
7. An electronic apparatus comprising:
the module according to claim 1 .
8. A moving object comprising:
the module according to claim 1 .
9. The module according to claim 1 , wherein the second functional element extends beyond an edge of the second base member.
10. A method of manufacturing a module comprising:
preparing a second base member provided with a first recessed section having a first wall section, and a second recessed section having a second wall section both disposed in a first surface, and a first base member having a hollow section disposed in a principal surface;
bonding the second base member and the first base member to each other so that the first recessed section and the hollow section are opposed to each other; and
removing the second base member in an area where the second recessed section and the second wall section are formed so that a part of the second wall section remains.
11. The method of manufacturing a module according to claim 10 , wherein
a half dicing process is used in the removing of the second base member.
12. A module comprising:
a first base member;
a second base member having an internal space with the first base member, and bonded to a principal surface of the first base member;
a first functional element housed in the internal space;
a second functional element connected to a surface of the second base member on an opposite side to the internal space with a bonding member;
an electrode electrically connected to the second functional element by a plurality of metal wiring lines, and disposed on the principal surface of the first base member in an area other than a connection area with the second base member; and
a projection section on only a single side of the second base member, formed of a same member as the second base member, and disposed on the principal surface in an area between the electrode and the second base member in a plan view,
wherein the plurality of metal wiring lines intersect with the projection section in the plan view,
wherein the second base member engages with the first base member to entirely cover the first functional element.
