The article compares two semiconductor industry leaders positioned to benefit from AI growth. Applied Materials manufactures chip-making equipment with strong margins (24.7%) but faces export control risks and higher valuation multiples. Amkor Technology provides assembly and testing services with lower valuation metrics but concentrated customer risk. The author recommends Amkor as the better value despite acknowledging both companies are ideal investments given their critical roles in the AI ecosystem.
