Quick answer: For analog, BCD, high-voltage and RF MPW, the first brief should describe function, voltage, frequency, device options, die area, packaging and test assumptions.

Specialty-process MPW requests fail when the RFQ says only a node number. Analog, BCD, high-voltage and RF projects depend on device options and test assumptions that are not visible from the node label.

Analog and mixed-signal fields

Circuit type: amplifier, ADC, DAC, sensor interface, clocking, PMIC or mixed-signal SoC block.
Voltage domains, IO requirements, matching, noise, linearity or frequency-sensitive needs.
Passive, resistor, capacitor, thick-metal or memory options that affect process fit.

BCD and high-voltage fields

Required voltage range, isolation, level shifting and power device assumptions.
Thermal, package and reliability needs for early feasibility screening.
Whether the project is prototype-only or has a product qualification path.

RF fields

Frequency range, RF passives, inductor needs, package parasitic sensitivity and test setup.
Whether wafer probe, packaged samples or characterization support is expected.
Any schedule constraint linked to demo, funding, customer sample or production decision.

FAQ

Why is node number not enough for specialty MPW?

Node number does not describe voltage devices, RF passives, embedded memory, thick metal, package parasitics or reliability needs. These process-sensitive details determine whether a specialty MPW case can be routed.

Can analog and RF requirements be in the same MPW RFQ?

Yes. The same RFQ can describe analog and RF requirements, but it should separate functional needs, frequency range, device options and test expectations so the case can be screened correctly.

Can MST guarantee a BCD or high-voltage MPW option?

No. MST coordinates and screens the case. BCD, high-voltage and RF process availability, pricing and schedule are confirmed case by case with a qualified partner.

Start an MPW RFQ

Start with node range, process family, estimated die area, target quantity, packaging or test assumptions, and timeline. Do not upload GDS, netlist, RTL, schematics or confidential design files at intake.

Submit an MPW RFQ or return to the MST mature-node MPW coordination hub.
