From concept to consumer
Semiconductor Supply Chain
Semiconductors power the digital economy. Their journey from an idea to a finished device depends on a specialized, globally connected supply chain—and ASE plays a critical role at its back end.
Why semiconductors matter
Semiconductors are the building blocks of modern electronics and essential infrastructure. They process information, store data, sense the physical world, manage power and connect devices in products ranging from smartphones and vehicles to medical systems and data centers.
The industry’s importance extends far beyond chip revenue. Research from Accenture and Oxford Economics cited by ASE estimated that semiconductors enable 22.5% of global GDP, while the global semiconductor market is expected to grow from roughly US$0.4 trillion in 2020 toward US$1 trillion by 2030.


What is a semiconductor?
A semiconductor is a material—most commonly silicon—whose electrical conductivity can be precisely controlled. Engineers form microscopic transistors, connections and other structures on a wafer to create integrated circuits that perform logic, memory, sensing, communications and power-management functions.
After wafer fabrication, individual dies must be separated, packaged, interconnected and tested. The package protects the die, moves electrical signals and power, removes heat and creates a usable interface to the larger electronic system.


The value chain
Concept to consumer
Some integrated device manufacturers perform several of these stages internally. The wider ecosystem also depends on suppliers of design software, intellectual property, manufacturing equipment, chemicals, gases, substrates, leadframes and other critical materials.
1. Design
Fabless companies and integrated device manufacturers define architecture, develop circuit designs and verify the chip before production.
2. Front-end manufacturing
Foundries build the integrated circuits layer by layer on silicon wafers using highly specialized process equipment and materials.
3. Back-end manufacturing
Assembly and test providers package, interconnect, inspect and test the dies, then prepare qualified devices for system production.
4. End-product integration
Electronics manufacturers combine semiconductors with boards, displays, sensors, batteries and software into complete products.
5. Consumption and services
Devices reach consumers and enterprises through brands, distributors, network operators and service providers.
