摘要:
This invention provides structures and a fabrication process for incorporating thin film transistors in back end of the line (BEOL) interconnect structures. The structures and fabrication processes described are compatible with processing requirements for the BEOL interconnect structures. The structures and fabrication processes utilize existing processing steps and materials already incorporated in interconnect wiring levels in order to reduce added cost associated with incorporating thin film transistors in the these levels. The structures enable vertical (3D) integration of multiple levels with improved manufacturability and reliability as compared to prior art methods of 3D integration.

An emission map of a circuit to be tested for alterations is obtained by measuring the physical circuit to be tested. An emission map of a reference circuit is obtained by measuring a physical reference circuit or by simulating the emissions expected from the reference circuit. The emission map of the circuit to be tested is compared with the emission map of the reference circuit, to determine presence of alterations in the circuit to be tested, as compared to the reference circuit.

A plurality of peripheral test structure substrate (PTSS) through vias is formed within a peripheral test structure substrate. A peripheral test structure layer and at least one functional layer are formed on one side of the plurality of the PTSS through vias. The other side of the plurality of the PTSS through vias is exposed throughout fabrication of the peripheral test structure layer and the at least one functional layer to provide access points for testing functionality of the various layers throughout the manufacturing sequence. C4 bonding may be performed after manufacture of all of the at least one functional layer is completed. A 3D assembly carrier or a C4 carrier substrate is not required since the peripheral test structure substrate has sufficient mechanical strength to support the peripheral test structure layer and the at least one functional layer.

An integrated circuit chip having micro-channels formed in multiple regions of the integrated circuit chip and a method of cooling the integrated circuit chip. The method includes for any region of the multiple regions, allowing a coolant to flow through micro-channels of the region only when a temperature of the region exceed a first specified temperature and blocking the coolant from flowing through the micro-channels of the region when a temperature of the region is below a second specified temperature.

Localized logic regions of a circuit include a local comparator electrically connected to a local resistive voltage circuit, to a local resistive ground circuit, and to a local register structure. The local comparator supplies a clock pulse to the local register structures when the local reference voltage is below a local voltage threshold. Activity in the local combinatorial logic structure causes the local reference voltage to drop below the local reference voltage independently of changes in the global reference voltage causing the comparator to output the clock pulse (with sufficient delay to allow the logic results to be stored in the registers only after setup times have been met in the local logic devices). This eliminates the need for a clock distribution tree, thereby saving power when there is no activity in the local combinatorial logic structure.

A multi-ported CAM cell in which the negative effects of increased travel distance have been substantially reduced is provided. The multi-ported CAM cell is achieved in the present invention by utilizing three-dimensional integration in which multiple active circuit layers are vertically stack and vertically aligned interconnects are employed to connect a device from one of the stacked layers to another device in another stack layer. By vertically stacking multiple active circuit layers with vertically aligned interconnects, each compare port of the multi-port CAM can be implemented on a separate layer above or below the primary data storage cell. This allows the multi-port CAM structure to be implemented within the same area footprint as a standard Random Access Memory (RAM) cell, minimizing data access and match compare delays. Each compare match line and data bit line has the length associated with a simple two-dimensional Static Random Access Memory (SRAM) cell array.
