The semiconductor industry is a hallmark of technological innovation, evolving rapidly to meet the demands of an increasingly digital world. At its core, semiconductor manufacturing involves two main stages: front-end processes, (wafer fabrication) and back-end processes (packaging and test). Wafer fabrication consists of creating microscopic electronic circuits on a silicon wafer. Packaging and test transform those wafers into finished chips with interconnects, ready for integration into devices like smartphones, computers, and countless other technologies.

Comparing today’s advanced semiconductor processes and manufacturing technologies with the simpler methods of the industry’s early years highlights remarkable progress driven by relentless innovation and problem-solving. The evolution of back-end packaging and test technologies and manufacturing showcases the industry’s ability to overcome formidable challenges by pushing the boundaries of what is possible.
