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.

How to use this chart

Toolbar

  • Range — 1M to MAX on daily closes. 1D/5D switch a US stock cell to 5-minute intraday bars; index and foreign cells fall back to 1M daily with a note.
  • Grid — 1×1 up to 2×2. Cells are synchronized: pan or zoom one and the others follow the same dates; the crosshair tracks across all of them. 4 INDICES loads Rubin · HALO · AEI · AW40 side by side.
  • Type / Scale — OHLC, line or area; linear or log price axis.

Picking a series

  • Tap the box in a cell's header to browse every Closelooknet series — headline indices, sub-indices, sectors, layers of all six families — plus the constituents.
  • Or type any ticker (NVDA, 7203.T, ASML.AS …) and press Enter — it charts in the cell straight from our data lake.

Studies

  • Overlays / Oscillators rows toggle the standard set (SMA, Bollinger, RSI, MACD …) per cell.
  • Levels (stock cells) draws the structure engine's support lines — regression bands, pivot cluster, SMA-200, the active fib zone.

Drawing

  • Tap a tool (Trend, Ray, H-Line, Fib, Channel, Rect, Note), then tap the chart once per point — the shape follows your finger or cursor between taps. The chart stops panning while a tool is armed; tap the tool again to release.
  • Drawings save per symbol in this browser and travel between the terminal and the asset page.
  • Delete key removes the selected drawing · Escape cancels a half-placed one · Clear wipes the symbol.

Wave counts

  • Wave places an Elliott count: tap the origin, then each wave end. Press Enter to stop early (inside wave 3 is fine) — dotted ghost targets sketch the remaining waves at guideline ratios.
  • On stocks the scanner's machine count appears automatically in grey — it is fully editable: drag any point, double-tap a label to remove it, Delete to dismiss it for good, Adopt to bring the machine's proposal back.
  • The sequence picker switches 1-5 / A-B-C / A-E / W-X-Y-Z; 1 2 3 cycles the degree; Subdiv starts a one-degree-smaller child count inside a wave.

Sharing

  • Card exports the cell as a branded PNG — chart, drawings and levels exactly as shown.
