The semiconductor value chain runs from chip design and wafer fabrication through equipment, materials, testing and packaging to system manufacturing and final hardware. The Singapore Technology sector is positioned primarily in equipment, testing, and hardware segments. Across the 49 stocks in the local Technology sector, around a dozen companies operate directly within the semiconductor production and testing chain. The majority are positioned in adjacent manufacturing, system integration, infrastructure, and software layers. These companies use semiconductors but do not participate in chip fabrication. These twelve companies span the core execution layers of semiconductor production. This includes testing and validation with $AEM SGD(AWX.SI)$
