The LTCC A6M Shared Run is a standardized MPW-style prototyping option for ceramic circuits and substrates built on Ferro A6M material. It combines a fixed stack-up with an available PDK, L-Edit layer definitions, and fast/slow DRC rule sets to support manufacturable submissions.
The LTCC@ETS platform offers an LTCC A6M Shared Run for multi-layer ceramic prototyping based on a fixed seven-layer stack. The shared run is intended for users who want access to a standardized LTCC process with design-rule support and repeatable fabrication conditions.
The shared run uses Ferro A6M tape and a predefined layer build of 182 µm / 182 µm / 89 µm / 35 µm / 89 µm / 182 µm / 182 µm, for a total fired thickness of approximately 941 µm ±1%. Top and bottom layers use solderable gold conductors, while the internal routing layers use silver conductors.
This offering supports high-frequency and compact ceramic designs while keeping the process constrained for MPW access. In this shared run, open and closed cavities are not offered, and resistors are available on layer 7 only. Projects that need more flexibility can be addressed through a dedicated LTCC fabrication flow.
Applications
The LTCC A6M Shared Run is suited to a wide range of compact ceramic and high-frequency implementations, including:
- Ceramic packaging and interposers
- Low-loss RF, microwave, and mm-wave circuits
- Compact passive structures and lumped-element networks
- Thermal management through metallized vias
- High-density interconnect substrates for wire-bond or flip-chip assembly
- Research and prototyping designs that benefit from a standardized LTCC stack and rule deck
Support
- Designers should review the LTCC A6M Shared Run PDK during the design phase and run DRC before submission.
- The shared run requires a single GDS or DXF database at 1:1 scale. Export in GDSII stream format and make sure the topcell name matches the design name.
- Layouts should merge all layer structures properly, and vias should be drawn as circular features only, without overlapping circles on the same layer.
