Abstract
Chip mounting is provided in which the pitch between bumps can be further narrowed without establishing contact between bumps. In a chip mounting structure in which a flip-chip bond has been established between a chip and a board via bumps, the bumps are provided so that the height position of the bumps from the connection surface of the chip or the connection surface of the board has a difference in height exceeding the thickness of adjacent bumps. This further narrows the pitch between bumps without establishing contact between the bumps.
