Patent ID: 7638362

Claim:
A method of manufacturing a memory module having a memory core chip for storing information, an interface chip for controlling data input/output to/from said memory core chip, and an interposer chip for transmitting/receiving the data between said interface chip and an outside, said method comprising the steps of: adhering a support directly to a surface of said interface chip opposite to a surface on which a bump is formed; subsequently placing said memory core chip on the surface of said interface chip on which the bump is formed, and thermo-compression bonding the bumps of said interface chip and said memory core chip to each other; and placing said interposer chip on said memory core chip, and thermo-compression bonding the bumps of said memory core chip and said interposer chip to each other, wherein said support holds said interface chip, said memory core chip and said interposer chip at said thermo-compression bonding steps.
