Company snapshot — DISCO Corp

6146.T in five paragraphs: what it makes and sells, where it sits in the Closelooknet stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
DISCO Corp makes precision machines that dice and grind semiconductor wafers, cutting a finished wafer into individual chips ready for packaging. It is based in Japan and its tools are used by chipmakers and outsourced assembly-and-test houses.
Where it sits in the stack
In our index, the Rubin Build-Out 100, DISCO sits in Layer 3 — Assembly & Test, within the Wafer Processing & Precision sleeve, the stage that turns a processed wafer into separate die before advanced packaging. It is a constraint on that sleeve because precision dicing and grinding for advanced packaging depends heavily on its tools.
Who it is priced against
The diary has no formal peer group set for DISCO; the comparison the market draws is with Tokyo Seimitsu, another maker of wafer dicing and grinding equipment.
Why Closelooknet tracks it
DISCO holds a seat in the Rubin Build-Out 100 and carries a Closelooknet score, though only one module has been scored so far, so the score is still being built. It appears in the diary's Dossier on the AI chip constraint chain and in the Morning 10 when the Tokyo equipment names move together.
What the diary watches
The diary watches whether the concentration of precision dicing and grinding capacity described in earlier notes holds as advanced packaging volumes grow, and whether the stock keeps moving in step with the wider Tokyo equipment group.

DISCO Corp (6146.T) trades on the TSE exchange in Japan, and sits in Layer 3 of the build-out stack. Constituent of Rubin Build-Out 100.
