An embodiment bonded integrated circuit (IC) structure includes a first IC structure and a second IC structure bonded to the first IC structure. The first IC structure includes a first bonding layer and a connector. The second IC structure includes a second bonding layer bonded to and contacting the first bonding layer and a contact pad in the second bonding layer. The connector extends past an interface between the first bonding layer and the second bonding layer, and the contact pad contacts a lateral surface and a sidewall of the connector.

A sensor array and a read-out circuit are prepared. The sensor array and the read-out circuit are aligned such that each first electrode and each second electrode face each other in a state where a connection material is disposed between a second area of the sensor array and a fourth area of the read-out circuit. The read-out circuit is pressed against the sensor array with a first load such that the sensor array and the readout circuit are bonded by the connection material with a gap provided between each first electrode and each second electrode. The read-out circuit is pressed against the sensor array with a second load larger than the first load so that each first electrode and each second electrode are connected. Before the pressing with the second load, either one of the first electrode and the second electrode has a conical shape.

A semiconductor device may include a first plate-like element having a first substantially planar connection surface with a first connection pad and a second plate-like element having a second substantially planar connection surface with a second connection pad corresponding to the first connection pad. The device may also include a connection electrically and physically coupling the first and second plate-like elements and arranged between the first and second connection pads. The connection may include a deformed elongate element arranged on the first connection pad and extending toward the second connection pad and solder in contact with the second connection pad and the elongate element.

A package structure includes a semiconductor device including a conductive feature, a joint layer, a pillar structure, an encapsulant and a RDL structure. The joint layer is disposed on the conductive feature. The pillar structure is disposed on and coupled to the semiconductor device through the joint layer.

A module includes a substrate, a plurality of components on an upper surface of the substrate, a component on a lower surface of the substrate, solder balls on the lower surface, sealing resin layers stacked on the upper surface and the lower surface of the substrate, and a shield film covering a side surface and an upper surface of the module. Part of each solder ball is exposed from a surface of the sealing resin layer, and the exposed parts are shaped to protrude from the sealing resin layer. The module can be connected to a mother substrate by connecting the protruding parts of the solder balls. There are gaps between the solder balls and the sealing resin layer, and the occurrence of cracks in the solder balls can be suppressed by reducing stress arising from a difference in thermal expansion coefficient between the solder and the resin.
