Sources of Value Creation1
- World-leading microprocessing technology
TOK is the manufacturer with the largest global market share for semiconductor photoresists.*2 TOK's purpose of contributing to a sustainable future through chemistry is supported and prac-
ticed by the three core competences of microprocessing technology, high purification technology, and customer-oriented strategies.
TOK developed semiconductor photoresists for the first time in 1968, and since that time, the company has continuously upgraded its microprocessing technology, which contributes to the higher performance, lower power
consumption, lower cost, and smaller size of semiconductors,
thereby consistently satisfying social expectations with its final products.

*5 Includes TOK's estimates for the decades shown
*6 A rough estimate for two-dimensional semiconductors (1970: 10,000 nm ➞ 2022: 5 nm); Based on scaling laws where miniaturization in line width to approximately 1/2,000 of the original size leads to power consumption of approximately 1/2,0002, or approximately 1/4,000,000.
