Concentrating on wafer cleaning — the pivot to semiconductor equipment (1992)

Sighting the process you can win, and massing resources there

What this decision shows is the weight of choosing where to mass resources among the several hundred steps of semiconductor manufacturing. Rather than the exposure or deposition steps that make an equipment maker conspicuous, Dainippon Screen Manufacturing chose cleaning — unglamorous, but decisive for yield — as its main battlefield. The surface-treatment and liquid-handling skills honed in photoengraving carried over directly into semiconductor cleaning; continuity with the founding trade underpinned this concentration on a single point. The character of the choice shows in its refusal to spread across step after step, instead sighting the domain it could win and massing resources there.

That said, a way of fighting that bets deeply on a single process is, in reverse, one whose results swing hard with the cycle and the competition in that process. That the company, having stood first in the world in cleaning, later lost share shows the strength and the peril of concentration at once. Even so, this shift — a printing company remade into one that earns its living from semiconductor cleaning — conveys how the judgment of discerning where one’s technology lives and massing resources there can redraw the very outline of a company. Which semiconductor process to bet on — that is a question the makers still face today.
