The semiconductor sector is a cornerstone of modern technology, driving everything from smartphones to data centers. The article provides an in-depth look at the industry, explaining the semiconductor supply chain, which includes design, manufacturing, assembly, and integration. Key players include fabless companies like Nvidia and Broadcom, foundries such as TSMC and Intel, and integrated device manufacturers (IDMs) like Infineon. The sector is valued at around $600 billion, with significant involvement from companies specializing in everything from silicon wafer production to assembly and testing. The article highlights the geopolitical landscape affecting semiconductors, particularly the tensions between the US and China, which push for reshoring and regionalization. This environment is driving innovation and complexity in the supply chain. For instance, the manufacturing process involves multiple steps, with companies like ASML at the forefront, producing lithography machines essential for chip fabrication. The rise of China as a semiconductor power adds another layer of competition and complexity. Chips themselves are intricate structures, usually made from silicon, composed of billions of transistors that serve as the backbone of electronic devices. The manufacturing process has seen advancements that allow for smaller transistor sizes and increased layer counts, such as 94 layers for 7nm chips and up to 115 layers for 5nm chips. The article breaks down the main categories of semiconductor products: logic chips, which account for 42% of revenues, and memory chips, making up 26%. Each segment plays a critical role in computing, influencing everything from personal gadgets to industrial applications.
