The demand for cleanroom construction is driven by risk aversion due to US-China decoupling and the need for AI computing power [1][5] - The electronics industry is the primary contributor to cleanroom demand, accounting for 70%-80%. In capital expenditures for chip wafer fabs, engineering costs represent 20%, with cleanroom systems making up 60% of that [1][7] - The cleanroom industry has high barriers to entry due to complex technology and high customization, leading to deep binding relationships between clients and service providers. Taiwanese service providers are benefiting from the trend of overseas factory construction [1][10] Market Dynamics - The cleanroom engineering sector has shown strong performance this year, driven by changes in both demand and supply. The global demand for AI infrastructure has surged, leading to significant growth in cleanroom engineering [3][4] - The US and Southeast Asia cleanroom markets are in a developing phase, facing severe labor shortages, which has allowed engineering service providers to increase their prices and improve profit margins [4][14] - Despite significant price increases in major stocks, there remains investment potential due to the ongoing demand for higher production cleanliness and the need for new capacity construction driven by AI computing and supply chain security [5][18] Future Growth Sources - The macro trend indicates that smaller process nodes correspond to higher production precision requirements, leading to increased investment density per unit area.
