Intel received 40 U.S. grants on Aug. 11 across two capitalization variants of its assignee name, and one record puts refrigeration at the scale of circuitry blocks rather than at the package or server level. Transistor-Scale Thermoelectric Devices for Refrigeration of Integrated Circuits (US12707971B2) claims thermoelectric devices positioned between transistor fins and a heat spreader. Its first claim requires alternating thermoelectric elements whose lateral pitch is no more than five times the transistor-fin pitch, placing the claimed cooling structure close to the dimensions and locations of the heat-producing circuitry.

This is an issued grant, so the operative coverage is the allowed claim language rather than the abstract alone. Claim 1 divides an integrated-circuit die into first and second circuitry blocks and assigns a thermoelectric device to each block beneath a shared heat spreader. Claim 3 allows independent power connections to the two cooling devices. Claims 4 and 5 add nanometer-scale distance and width limits. Claims 6 and 11 recite cooling structures capable of achieving operating temperatures at or below minus 25 degrees Celsius, a demanding embodiment that the patent states without reporting system efficiency.

What the record actually covers

The business relevance lies in where the control boundary sits. A package-level cooler treats the die as one thermal load; separately powered thermoelectric devices can target different blocks. That could make cooling capacity follow local activity, at least within the claimed architecture. The grant does not quantify the thermoelectric coefficient, electrical overhead, reliability, manufacturing cost or net performance gain. It also does not identify a commercial processor. Those omissions prevent a cost or product conclusion, but they do not erase the portfolio fact that Intel now holds an issued claim on independently powered, block-aligned thermoelectric structures.

The material options are deliberately broad across dependent claims: silicon of complementary conductivity types, metal, zinc and oxygen, or combinations involving germanium, indium, gallium, bismuth, antimony or tellurium. Copper appears as a heat-spreader option. That menu shows the patent is not confined to one thermoelectric compound, while the dimensional and positional limitations remain. A granted claim can create coverage without proving that every listed material is equally practical. The record should therefore be read as a map of allowed structures, not a manufacturing announcement.

The rest of Intel's issue-day cohort fills out the physical stack around that thermal idea. Singulation of Integrated Circuit Package Substrates With Glass Cores (US12708014B2) addresses stress and corner structures when separating packages built on glass cores. Substrate With Low-Permittivity Core and Buildup Layers (US12708013B2) uses hollow glass fibers in a low-permittivity substrate core. Both grants concern package substrates, an area where electrical performance, panel handling and mechanical durability meet. Their presence alongside transistor-scale cooling suggests coverage at multiple distances from the active devices, though the records do not say they belong to one product platform.

The portfolio context

Closer to the transistor, Contacts With Interface Fermi Level Tuning Layers (US12707691B2) places transition-metal dichalcogenide monolayers between a contact metal and semiconductor to tune the Fermi level and reduce a Schottky barrier. Technologies for Low-Leakage On-Chip Capacitors (US12707654B2) arranges low-leakage on-chip capacitors with field lines parallel to a high-k dielectric layer. Those grants address contact resistance and stored charge, respectively. They are not cooling patents, but each attacks a scaling penalty that becomes more important as feature dimensions and power density tighten.

Farther out, Stackable Memory Module With Double-Sided Compression Contact Pads (US12707566B2) covers stackable memory modules with compression contacts on both sides of a board. The issue-day set therefore runs from device contacts through on-die capacitors and local refrigeration to glass-core substrates and modular memory. A count of 40 grants is not a ranking of quality or market power; it is a dated inventory across programs with different priority histories. The useful signal is the distribution of technical control points Intel chose to protect.

An issue-day coverage map is a portfolio view, not a quality score. Each selected grant has an independent prosecution history, priority chain and claim boundary, even when several records address neighboring parts of a system. The grant date establishes that claims issued; it does not establish adoption, revenue, manufacturing readiness or infringement by another company. Likewise, a large daily count can reflect docket timing as much as a coordinated release. The useful analysis is to place each allowed claim at a technical control point and observe how those points relate: device, interconnect, package, enclosure, sensor, power path or user-facing function. That map can show how a company has distributed issued coverage without assigning strength or economic value to any one record. Dependent claims and specification examples also need separation from the independent claim. They can describe important embodiments, but they do not broaden the allowed combination and may not be required by the broadest coverage. Any competitive conclusion would additionally need claim construction, product evidence, remaining term, family status and prior-art analysis that the issue-day list does not provide. The records here therefore support a factual inventory of newly issued positions. They do not support a moat ranking, freedom-to-operate opinion, damages estimate or prediction about how the company will use the grants.

The thermoelectric grant's clearest commercial implication is optionality around local thermal management. It gives Intel issued coverage on a configuration where separate circuitry blocks can have separate thermoelectric devices and power connections under a common heat spreader. Whether that coverage affects a shipping architecture depends on implementation facts not in the patent. What can be said from the Aug. 11 record is that cooling, contacts, capacitors, package substrates and memory interconnects all appeared in the same Intel grant cohort, mapping a portfolio across several bottlenecks of dense compute hardware.
