Opportunity Summary:

DARPA Microsystems Technology Office posted Broad Agency Announcement (BAA) DARPA-BAA-13-21 titled ICECool Applications (ICECool Apps) to fund research aimed at breaking the thermal bottlenecks that limit high-performance military electronics. The program sits in the science and technology R&D category (CFDA 12.910) and is intended to support disruptive cooling and heat-spreading approaches that can keep next-generation electronics operating within normal temperature limits, while also reducing size, weight, and power (SWaP). In practical terms, ICECool Apps targets the heat problem that shows up when you push RF power amplifiers and embedded computing hardware to higher power densities: performance rises, but localized hot spots and overall heat flux quickly become the limiting factor unless the thermal design changes dramatically.

The technical focus of ICECool Apps is chip-level heat removal at extremely high heat flux levels, described as kilowatt-class heat flux and heat density, with explicit attention to controlling very small, sub-millimeter hot spots (for example in high-power transistor regions). Rather than relying on conventional heat sinks and system-level cooling, the effort emphasizes cooling solutions integrated close to, within, or between chips. The BAA highlights approaches such as intra-chip and/or inter-chip microfluidic cooling, along with on-chip thermal interconnects, meaning engineered pathways that move heat efficiently out of hot regions into a cooling structure. The intent is to enable higher-performing RF power amplifiers and embedded computing systems by removing heat where it is generated, fast enough and locally enough that devices can operate in their commonly accepted temperature range even under aggressive electrical loading.

Administratively, the notice referenced an Amendment 01 that updated the solicitation. That amendment had three main purposes: first, it revised or corrected the HEMT (high electron mobility transistor) hot-spot flux metric used throughout the BAA, especially in Table 1 and Table 2, which matters because those tables typically define performance targets, evaluation metrics, or phase goals. Second, it made general administrative and wording revisions. Third, it removed the original Attachment 1 and replaced it with a new Attachment 1 identified as a Cost Proposal Checklist, clarifying what proposers must include in their cost submission. The amendment notes that changes were highlighted in yellow in the conformed DARPA-BAA-13-21 document, and proposers were expected to rely on that updated version for accurate metrics and required attachments.

From a funding and eligibility standpoint, ICECool Apps was listed as a discretionary opportunity and allowed multiple award instruments, including cooperative agreements, grants, other transactions/procurement contracts, depending on what DARPA determined appropriate for a given effort. Eligibility was described as unrestricted (open broadly to different entity types), subject to any additional constraints contained in the full text of the announcement. The opportunity did not require cost sharing or matching. Standard listing fields showed no explicit award floor or ceiling (both recorded as 0), which usually means the solicitation itself, rather than the synopsis, contains the details on anticipated funding levels, number of awards, or project scale.

Key dates in the posting show it was originally posted February 6, 2013, created in the system February 12, 2013, with an original and current closing date of March 22, 2013, and an archive date of September 23, 2013. The point of contact listed for access issues was Dr. Avram Bar-Cohen, the DARPA/MTO program manager associated with the BAA, and the solicitation could be found via the MTO Solicitations page. Overall, ICECool Apps can be read as a push to move cooling technology into the chip and package itself, so that future RF and computing hardware can run harder without being throttled by hot spots, bulky thermal hardware, or SWaP penalties.
