Fab.exe

An old fab, a fresh start

Fab.exe is a single-player factory-management game about turning an aging cleanroom into a reliable semiconductor fab. Place the right tools, follow each lot through the line, and make practical decisions when capacity, quality, time and cash all compete for attention.

Read the factory, then improve it

FOUPs move through the fab on AMHS routes while queues build around lithography, etch, deposition, metrology and packaging. Watch the flow, find the real bottleneck, add matching capacity, plan maintenance and keep work in progress under control.

Protect yield and keep your promises

A busy line is not always a healthy line. Investigate defect patterns, adjust sampling, manage equipment wear and balance urgent contracts against long-term stability. Every improvement has a cost, and every delay has a consequence.

Grow through 32 story missions

Start at N28 and guide the fab through new process generations toward N2 and A10. The campaign introduces the systems step by step, then asks you to combine them as the factory becomes larger and more demanding.

What you will manage

Process-specific tools, footprints and visible loadports FOUP movement, AMHS flow, queues and dispatch priorities Yield, Cpk, WIP, delivery, contracts and inventory Preventive maintenance, metrology sampling and research Multi-phase expansion and 32 handcrafted story missions

The entire in-game interface is localized in English, Traditional Chinese, Simplified Chinese, Japanese, Korean, French, Spanish, Italian, German, and Brazilian Portuguese.

Choose how you run your fab

Story: 32 handcrafted missions introduce the systems step by step, with objectives and ratings. Free play: run an open-ended factory, research new processes and expand at your own pace. Endless Fab: no time limit or fixed victory target. Keep adding Phases and tools, pursue recurring goals and expansion tiers, and continue technology upgrades beyond A10. Choose a standard, wealthy or N7 start, with normal, mild or frozen rival growth. Bankruptcy remains possible. Daily and weekly challenges: seeded runs with changing conditions and scoring goals.

Update 0.34.7 — what changed

Layout overhaul: goals, bids and the line monitor now share a tabbed panel on the right, and the main toolbar moves to the bottom, so you see more of the fab. Quarterly reviews and decision events fit on one screen. Buttons now give a subtle press wiggle (can be turned off under Settings → Accessibility), and every screen was checked and fixed across all 10 languages, resolutions and UI scales. Endless Fab: a goal that isn't completed within 20 in-game minutes is now swapped for a new one, so the goal chain can no longer get stuck (for example on a Cpk target the fab can't reach). Fixed decision pop-ups (for example the UPW water-quality excursion) that could not be closed and blocked play. Mouse-wheel zoom now zooms toward the cursor. The first launch follows your system language. A red placement preview now tells you why the tool cannot be placed. Fixed the settings panel closing when you clicked a tab or option, and Esc now closes every dialog. Full localization pass: once you pick a language, menus, events, tutorial, story briefings, the process encyclopedia and cleanroom chatter all appear in that language only. All ten languages were reviewed line by line. Buttons and labels fit longer languages at every resolution and interface scale; the Endless Fab options are easier to read. The save-slot screen shows whether Steam Cloud is syncing your saves. Balance: Chiplet packages are valued from the wafers inside them, the design tree no longer multiplies prices fourfold and its unused nodes now work, yield-investigation symptoms no longer reveal the culprit, and demand forecasts no longer give away the answer. Many smaller fixes to saves, achievements, contracts, events, audio and layout.
