This is a Sources Sought Notice ONLY. Requests for copies of a solicitation will not receive a response.

This Notice is for planning purposes only and is not a Request for Proposal, Request for Quotation, or an obligation on the part of the National Institute of Standards and Technology (NIST) for conducting a follow-on acquisition. NIST does not intend to award a contract based on this Notice or otherwise pay for the information requested. No entitlement or payment of direct or indirect costs or charges by NIST will arise because of submission of responses to this Notice and NIST use of such information.

NO SOLICITATION DOCUMENTS EXIST AT THIS TIME.

NIST is seeking information on commercial vendors that can provide fabricated arrays of tapered/conical doped-silicon micro-pillars on silicon wafer substrates.

Background Information

The National Institute of Standards and Technology (NIST), as part of the CHIPS for America program, is developing doped-silicon test and reference materials for use with atom probe tomography and other complementary materials characterization techniques. The reference materials will be most useful to analysts if provided as sharpened micro-pillar arrays that can be directly analyzed in the atom probe instrument.

Description of Requirement

The Contractor shall meet the following minimum requirements:

1. Be able to work with either 100 mm or 150 mm silicon wafer starting materials. The wafers will be provided either as bulk-doped or will have an epi-film deposited on the surface (film will be micrometers in thickness).


2. Be able to fabricate arrays of tapered/conical doped-silicon micro-pillars from the silicon wafer starting materials.
   
   
   
   1. The dopants will be common dopants for silicon, such as boron and/or phosphorus.
   
   
   2. The rough dimensions for each tapered/conical micro-pillar should be 150 micrometers in height and 75 micrometers wide at the base.
   
   
   3. The tip of each micro-pillar should be circular in cross section and roughly 100 nm in diameter to permit direct data acquisition in the atom probe instrument.
   
   
   4. The number of micro-pillars in each micro-pillar array will be 22 or 25.
   
   
   5. Each micro-pillar will be spaced roughly a few hundred micrometers from its neighbors.
   
   
   6. Since these are prospective reference materials, the epi-film or near-surface region of the bulk doped wafer starter material must be captured in the tips of the fabricated micro-pillars.
   
   
   7. The micro-pillar array pattern will be a custom asymmetric layout to permit the reference materials to be compatible with commercial atom probe data acquisition automation packages. NIST will provide a schematic of the array patterns.
   
   
   
   


3. Be able to fabricate additional features on the micro-pillar array coupons, such as plateaus, to permit analysts to perform complementary analyses using other materials characterization techniques.


4. Be able to dice the fabricated micro-pillar arrays into coupons with rough dimensions 10 millimeters by 5 millimeters.


5. Be able to work with small lot sizes for processing and fabrication, since these prospective materials are part of a reference material development effort.

Companies able to provide such services are requested to email a detailed response describing their abilities to both Cielo.Ibarra@nist.gov and Nathali.Clark@chips.gov, no later than the response date for this sources sought notice.

Small businesses are defined under the associated NAICS code for this effort:

1. 334413 – Semiconductor and Related Device Manufacturing, as those domestic sources having 500 employees or less. Please include your company’s size classification in any response to this notice.


2. 541713 - Research and Development in Nanotechnology, as those domestic sources having 1000 employees or less. Please include your company’s size classification in any response to this notice.

The report should include any information relevant to your capabilities. Also, please provide the following information as part of the response to this sources sought notice:

1. Name of company/companies that are authorized provide services, including address, and a point of contact for the company (name, phone number, fax number and email address), and UEI number


2. Indication of whether the services are currently on one or more GSA Federal Supply Schedule contracts or any other government-wide contracts. If so, please provide the applicable contract number(s).


3. Identify any aspects of the NIST market research notice, including instructions, and draft minimum specifications in the “Description of Requirement” section you cannot meet and state why. Please offer suggestions for how the market research notice and draft minimum specifications could be made more competitive.


4. Identify any customers in the public or private sectors to which you provided the recommended or similar services/equipment. Include customer(s) information: company name, phone number, point of contact, email address.


5. Minimum process and fabrication lot size requirements.


6. Any other relevant information that is not listed above which the Government should consider in developing its minimum performance requirements.


7. For the NAICS code listed in this notice:
   
   
   
   1. Indicate whether your company is (a) a small business or (b) other than small business. See the Table of Small Business Size Standards and the associated .pdf download file for small business size standards and additional information.
   
   
   2. If you believe the NAICS code listed in this notice is not the best NAICS code for the type of product addressed in this notice, identify an alternative NAICS code that you believe would be more appropriate for the planned procurement.
