Tesla(US:TSLA) Sou Hu Cai Jing·2026-01-08 04:40Core Viewpoint - Elon Musk confirmed that Tesla will establish its own 2nm wafer fabrication plant, expressing skepticism about the current methods used in the semiconductor manufacturing industry for cleanroom construction [3][4]. Group 1: Tesla's 2nm Wafer Fab - Tesla is planning to build a 2nm wafer fabrication facility, which Musk believes will revolutionize the manufacturing process [3]. - Musk humorously suggested that he could eat a cheeseburger and smoke a cigar inside the wafer fab, indicating a casual approach to the environment within the facility [1][3]. Group 2: Cleanroom Environment - Current cleanroom environments in semiconductor manufacturing are designed to be highly isolated, with wafers transported in nitrogen-filled boxes to maintain a micro-positive pressure environment [3][4]. - Cleanrooms are classified by ISO standards, with ISO 1 and 2 being the most stringent, allowing only a limited number of particles per cubic meter of air [4]. - Activities such as smoking or eating are strictly prohibited in ISO 1-3 cleanroom environments due to the risk of contamination from particles generated by human activities [5].
