Abstract

A detecting apparatus includes a multi-tier 3D integrated ASIC comprising one or more analog tiers and one or more digital tiers, and a sensor bonded to the multi-tier 3D integrated ASIC. The detecting apparatus includes an electrical substrate and a group of FPGAs or custom data management ASICs. The detecting apparatus also includes a thermal management system, a power distribution system and one or more connectors to transfer data to a data acquisition system configured for radiation spectroscopy or imaging with zero suppressed or full frame readout.

First claim

The invention claimed is:

1. A detecting apparatus head, comprising:
a mother board electronically and mechanically connected to at least one dead-zone-less detector module having a substrate;
at least one multi-tier 3D integrated ASIC (Application-Specific Integrated Circuit) comprising at least one analog tier and at least one digital tier connected to at least one segmented sensor, wherein at least one tier of said at least one multi-tier 3D integrated ASIC is bonded to said at least one segmented sensor and at least one tier of said at least one multi-tier 3D integrated ASIC is bonded to said substrate of said at least one dead-zone-less detector module;
at least one data processing, computation, and transmission circuit, wherein said at least one data processing, computation, and transmission circuit is mounted onto a side of said at least one dead-zone-less detector module opposite said at least one multi-tier 3D integrated ASIC;
a thermal management system comprising a cooling system that includes a chiller and a heat exchanger, wherein said heat exchanger is located within said detecting apparatus head and between said motherboard and said at least one dead-zone-less detector module.

2. The detecting apparatus head of claim 1 further comprising a power distribution system that includes at least one power supply that supplies power from said motherboard to said at least one dead-zone-less detector module.

3. The detecting apparatus head of claim 1 comprising a dead-time-less operation that continuously processes signals within user defined time frames.

4. The detecting apparatus head of claim 1 further comprising said at least one segmented sensor with a plurality of sensor pixels and a matching segmented analog tier with a plurality of analog pixels.

5. The detecting apparatus head of claim 4 wherein each analog pixel among said plurality of analog pixels includes at least a charge sensitive amplifier with sensor leakage current compensation, a shaping filter, at least one comparator, and at least one trimming digital to analog converter (DAC).

6. The detecting apparatus head of claim 4 wherein said at least one digital tier comprises a digital functionality for processing signals from said plurality of analog pixels of said at least one analog tier and transfers data off said at least one multi-tier 3D integrated ASIC.

7. The detecting apparatus lead of claim 2 wherein said at least one multi-tier 3D integrated ASIC is die-to-wafer bonded to a sensor layer of said at least one segmented sensor to configure an assembly comprising said at least one dead-zone-less detector module.

8. The detecting apparatus head of claim 7 wherein said at least one dead-zone-less detector module further comprises a plurality of additional electrical components which performs a plurality of functions including power distribution, distributes control and docks from said at least one data processing, computation, and transmission circuit and transfers data from said at least one multi-tier 3D integrated circuit to said at least one data processing, computation, and transmission circuit.

9. The detecting apparatus head of claim 7 wherein said at least one dead-zone-less detector module receives a plurality of signals including power, biases and clocks, and which transmits high speed, multiplexed and concentrated data to said motherboard of said detecting apparatus head.

10. The detecting apparatus head of claim 1 further comprising wherein said at least one dead-zone-less detector module, and said thermal management system for power dissipation placed in proximity to said at least one dead-zone-less detector module making direct contact to said at least one dead-zone-less detector module for heat exchange.

11. The detecting apparatus head of claim 9 wherein said detecting apparatus head transfers a large volume of high-speed data to a Data Acquisition (DAQ) system external to said detecting apparatus head for further processing or storage of said data.

12. The detecting apparatus head of claim 7 wherein said at least one dead-zone-less detector module includes additional circuitry and components that allow said at least one dead-zone-less detector module to function as a data concentrator, receiving data from said at least one multi-tier 3D integrated ASIC, processing said data and moving said data to said motherboard and then to said DAQ for further processing.

13. The detecting apparatus head of claim 1 wherein said at least one multi-tier 3D integrated ASIC comprises at least one analog tier and at least one digital tier, which are diced in a manner that a size of said at least one multi-tier 3D integrated ASIC is known after dicing with a precision better than a size of a gap planned between said at least one multi-tier 3D integrated ASIC to be placed one next to another on said at least one segmented sensor, and then die-to-wafer bonded to a sensor layer on one side such that a resulting assembly constitutes either said at least one dead-zone-less detector module or allows for a minimum gaps between ASICs.

14. The detecting apparatus head of claim 1 wherein said at least one multi-tier 3D integrated ASIC comprises at least one analog tier and at least one digital tier, which are diced in a manner wherein said at least one multi-tier 3D integrated ASIC possesses a same dimension as another said at least one multi-tier 3D integrated ASIC and does not include a peripheral material that results in uneven sizes of various dies.
