CoC, CoW : Chip on Chip, Chip on Wafer

Description

ㆍEfficient Integration : Mother and Daughter communicate efficiently at faster speed, lower inductance, and lower electrical resistance, ideally suited for high speed signal applications, e.g. Si photonics

ㆍMulti Die Capability : Mix of devices can be attached to create fully functional blocks, e.g. attaching a laser to Si photonics chip set creates the platform for an optical transceiver

ㆍSupport Legacy : Once sawn, the chip stack can be assembled into a various types of packages e.g. QSFP, QFN, fcCSP, PBGA, etc.

ㆍMultiple Structures : For example CoW POSSUMTM, CoW+WB, etc.
