Wafer-scale integration
Beginner
Building one single, giant chip out of a whole silicon wafer instead of cutting the wafer into many small chips.
Novice
Making one working part from all, or nearly all, of a wafer. Because no wafer is flawless, the design has to include spare pieces and route around the broken ones.
Expert
A monolithic part spanning many reticle fields, joined by wiring across the scribe lines, with redundancy at core and link level so every wafer ships. A variant bonds known-good chiplets onto an interconnect wafer instead.
