Definition
Semiconductor manufacturing is a linked design and production system that converts an electronic specification into patterned devices, multilayer interconnects, tested die, and qualified packages.
Process position
Inputs

How it works
- 01Define and verify the chip architecture
- 02Translate the design into physical layout and masks
- 03Prepare and qualify wafers
- 04Repeat deposition, lithography, etch, doping, clean, and planarization cycles
- 05Form contacts and multilayer interconnects
- 06Probe wafers and singulate die
- 07Assemble, package, and provide power, signal, and thermal paths
- 08Run final test, qualification, and failure analysis
The manufacturing loop
A chip is built by repeatedly creating a material layer, patterning it, removing or modifying selected regions, measuring the result, and deciding whether the wafer can continue. Front-end device formation and back-end wiring are physically different, but they share the same control logic: each step inherits variation from the previous step and creates constraints for the next.
Design and manufacturing are coupled
The process begins before a wafer enters a fab. Architecture, libraries, physical-design rules, masks, package assumptions, and test strategy define what the manufacturing flow must achieve. Yield learning then feeds back into design rules and product choices.
Lithography transfers reticle patterns into photosensitive material, after which development and etch convert that image into physical wafer structures.
Packaging is part of system performance
Modern packages carry power, signals, memory, mechanical protection, and heat. For multi-die products, package architecture can determine bandwidth, latency, thermal limits, and how much known-good silicon is exposed to an assembly failure.
Advanced packaging combines multiple die and interconnect technologies to optimize system-level performance, power, form factor, and cost.
