Deformable semiconductor device
View Patent ↗A semiconductor chip is secured in a state deformed into a substantially cylinder shape by a coating material formed on its surface. The deformed semiconductor chip is flip-chip connected to an interposer and sealed with sealing resin onto the interposer. Solder balls are provided, as external terminals, on the other side of the interposer.
1. A semiconductor device, comprising:
at least one semiconductor chip;
a setting member that is formed on a surface of the semiconductor chip and is configured to set the semiconductor chip into a deformed shape corresponding to one of a substantially cylinder shape and a curved shape;
a package substrate to which the deformed semiconductor chip is flip chip connected;
a sealing resin that seals the semiconductor chip onto the package substrate: and
an external connection terminal that is provided on the package substrate wherein the deformed semiconductor chip is flip chip connected only at outer edges of said semiconductor chip.
2. The semiconductor device as claimed in claim 1 , wherein the setting member corresponds to a resin layer that is formed on an inner side surface of the substantially cylinder shaped or curve shaped semiconductor chip.
