Custom Silicon Carbide Transistors

NIST-FY25-CHIPS-0095

6695 / 334516

Title:  Custom Silicon Carbide Transistors

BACKGROUND

The National Institute of Standards and Technology (NIST) requires the design and fabrication of custom silicon carbide transistors on pre-diced 5 x 5 mm2 substrates. The substrates must be provided by NIST and will have an epitaxial layer with modified isotopic ratio. The transistors will be used to further our research of quantum-based magnetic field sensors with the goal of improving SWAP-C optimization of the technology for a variety of application spaces.

Minimum Requirements

The items shall meet or exceed the minimum requirements identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, or prototype equipment will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the proposer is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable. All specifications below must be verified at NIST before final acceptance.

The custom silicon carbide transistors will meet the minimum salient characteristics identified below.

1. Shall be fabricated using NIST-provided 5 x 5 mm2 substrates.


2. All fabrication steps must accommodate the small sample size.


3. Shall be designed with input from the NIST team; iterative design with layout drafts is required before fabrication.


4. Shall be fabricated with steps that mimic an industrial process flow.


5. The process used must be capable of producing functional metal-oxide-semiconductor field-effect transistors (MOSFETs) with measurable threshold voltage.


6. The transistor gates must be able to withstand a voltage of 20 V for 10 minutes without catastrophic breakdown.


7. The fabrication process must not damage or replace the isotopically-enriched epitaxial layer present on the NIST-provided substrates.


8. Each 5 x 5 mm2 substrate should contain as many transistors as possible or a minimum of six.
