Budget Silicon Manufacturing

Get 1,000 custom silicon dies from as low as $2 per die with early bird pricing. wafer.space‘s third production run on GlobalFoundries’ GF180MCU 180 nm mixed-signal process is open for purchase. You design your chip, we handle fabrication, dicing, and delivery. No gatekeeping, no opaque quotes, no five-figure NRE.

Run 3 builds off of the successes we had in both Run 1 and Run 2. Many designs were submitted by universities, companies, hobbyists and community groups from around the world. Now we are doing it again, with another new slot size, better tooling, and lessons learned from our previous runs.

Remember PCBs before OSH Park?

Orders were painful: opaque quotes, setup fees, big MOQs, long waits, and DIY panelization. Then pooling services like OSH Park fixed it with predictable pricing, frequent runs, and no-nonsense logistics. wafer.space brings that shift to silicon.

What’s New in Run 3

Run 3 introduces several improvements based on what we learned from shipping Run 1 & 2.

Slot Sizes and Pricing

Run 3 offers four slot sizes. All sizes use the same GF180MCU process, the same padframe infrastructure, and the same submission platform. Every slot includes 1,000 dies.

Standard Price$8,000 ($8/die)$5,000 ($5/die)$5,000 ($5/die)$3,000 ($3/die)

Usable silicon is the die area minus the seal ring (~26 um each side). This is the area available when using a custom pad ring or no pad ring. Core area is the area inside the default pad ring.

For detailed slot specifications including padframe layouts and design constraints, see the slot size documentation.

Choosing a slot size: The 0.5x1 (half width) gives a tall, narrow die, ideal for I/O-heavy designs where signals concentrate along the long edges. The 1x0.5 (half height) gives a wide, short die, ideal for designs that benefit from a wider core. The 1x1 (full) provides maximum area for complex SoCs and mixed-signal designs. These three sizes share the same 56 I/O pad configuration, but the half-sized ones miss out on two extra power pads. New for this run, 0.5x0.5 (quarter) provides a smaller die at a much lower price point. Ideal for prototyping designs which don’t need the area offered by the other slots, but still just as capable as they all target GF180MCU. The quarter slot provides 48 I/O pads and 8 power pads.

Chip-on-Board Packaging

Receive your dies wire-bonded onto small PCBs, ready for testing and integration. Learn more about the process in our progress update.

Add-on to any slot purchase. Costs $1,500 ($1.50/die).

Chips can be delivered as bare dies in tape-and-reel, or wire-bonded onto chip-on-board PCBs.

Process Technology

How It Works

  1. Purchase a slot during the campaign. Choose the slot size that fits your design.
  2. Design and verify using the open GF180MCU PDK and your preferred flow (e.g., LibreLane/OpenROAD, proprietary, or mixed).
  3. Run sign-off checks (DRC/LVS/ERC/antenna) and follow pad/ESD guidelines.
  4. Submit your design through platform.wafer.space by the submission deadline.
  5. Fabrication in the pooled MPW at GlobalFoundries.
  6. Dicing and logistics after wafers return.
  7. Delivery of your bare dies (and packaged parts if selected).

The gf180mcu-project-template provides a ready-to-use starting point with LibreLane configuration, a Nix-based development environment, cocotb testbenches, and example designs. Clone it, drop in your Verilog, and run make librelane to go from RTL to GDS.

Getting Started

If you need professional design help, several companies offer paid engineering services for GF180MCU designs. Options include full custom design, verification help, or guidance on a first tapeout. See the design help page for details.

FAQ

Can I get a formal quote or pay via wire?

Payment via wire or ACH is available for wafer.space slot orders. To do so, or if your organization requires a formal quote, please submit a request to Crowd Supply via the contact form. Be sure to include your name, organization, address, phone number, email address, and a list of the slot sizes and packaging you would like. Payment instructions will be included along with the invoice for a submitted order. Your order must be paid in full before the slot purchase deadline. To receive early bird pricing, your order must be paid in full prior to the end of the early bird discount period.

Do I have to open-source my design?

No. The PDK is open; your design can be open or closed.

What changed between Run 3 and the previous runs?

The main changes are: a new smaller slot, stricter and more comprehensive DRC checking, an improved submission platform, and overall improvements to the toolchain. The process, foundry, and overall approach are the same.

Which slot size should I choose?

It depends entirely on your design. For maximum core area, consider the 1x1 slot with its 12.92 mm² of core area. If your design is smaller, or is I/O heavy, then the half slots may offer a better shape for your design. If your design is even smaller, then the quarter slot offers
the lowest cost of entry. Check the slot size documentation for detailed comparisons.

Can you help me with a pad ring?

No, but the community has created example pad rings and reviews of common pitfalls. The gf180mcu-project-template includes a default padframe configuration, and there are previous public designs you can use as references.

How many I/O pads can I use?

The full slot supports 56 I/O with 74 pads total. The half-sized slots also support 56 I/O, but total pad count is reduced to 72. The quarter-sized slot has 48 I/O with 56 pads total. The actual number you use depends on your pad pitch and die edge budget.

Can I put multiple designs in one slot?

Yes. You own the full die area of your slot.

Can I use previous designs as a starting point?

Absolutely. 29 public repositories from Run 1 are listed at github.com/wafer-space/ws-run1. Several of these include detailed documentation of their design process and decisions. Note that slot dimensions have changed slightly, so you will need to adjust padframe configurations. The project template is the best starting point for new designs.

Where will my chips be made?

Fabricated on GF180MCU at GlobalFoundries in Singapore. Dicing and logistics via qualified partners. Final shipping from Singapore or our fulfillment partner.
