Innovative CZT Packaging and Radiation Detection Development Fabrication of complex gamma sensors poses many challenges. Designing the right package becomes critical to ensuring optimal performance of your sensor. At Creative Electron, we are focused on creating custom gamma sensors that can meet your special needs. As a leading manufacturer of state-of-the-art flip-chip products, we have applied our years of experience to solving your sensor packaging challenges. Our novel technologies in design, fabrication and low-cost production of sensor products have emerged from our core know-how in high density electronics.
As a turn-key supplier, we can help you from design to final assembly and testing. Other CZT packaging technologies also available (epoxies and solders). Creative Electron acquired all IP and assets of Aguila Technologies in 2008.
Exclusive XTALBond ® packaging material:
- Directly attaches to ASICs or substrates
- Reworkable
- Robust*: shear force > 2,500psi
- High inter-pixel impedance*: 100GΩ/mm
- Low bump-bond resistance*: 10μΩ/mm
- Low assembly temperature: 110°C
For example, we have brought our experience in packaging to the fabrication of practical CZT detector array modules. The result is a new detector packaging technology that is revolutionizing the emerging CZT detector field. CEI’s patented sensor technology comprises a flip-chip CZT sensor bump-soldered onto a high-density printed circuit or ASIC using our revolutionary reworkable chip-stacking technology. This low-profile package can be designed into planar arrays of unlimited size. If we can accomplish something as revolutionary as this, just think what Creative Electron can do for you. Let our experts design and fabricate a custom sensor package for you. We'll help you get it right the first time!
Cadmium Zinc Telluride
Cadmium Zinc Telluride (CZT) has long been known to possess the stopping power, room temperature sensitivity and spectral resolution required for hard X-ray and gamma-ray detection, but fabrication issues had prevented its use as a viable detector in many applications in nuclear medicine, astrophysics, homeland security and industrial x-ray imaging.
This is no longer a problem, however, thanks to Creative Electron’s research and development. Creative Electron’s patented sensor technology comprises a flip-chip CZT sensor and one of three different bonding technologies: epoxy-based, solder-based, and a novel hybrid approach which offers almost unlimited reworkability of CZT crystals and the corresponding high-desnity printed circuit or ASIC. Our low-profile package can be designed into planar arrays of many different sizes.
What makes this package possible are our reliable electrode metallizations and our low-temperature bonding technologies. Our CZT detector technology can easily be adapted to any number of applications, including mammography, PET and SPECT imaging systems, astrophysics X-ray detection, and high-resolution nuclear spectrometers for homeland security and defense systems.

Medical Voice Recorded - Creative Electron

By providing a small form factor solution, analogous to the current dog tag, capable of withstanding physical and environmental insult as well as actively reducing ambient noise, pertinent medical information could be carried forward in a secure and continuous fashion. MVR will replace the existing method of documenting casualties in theater, which is in most cases writing on the warfighter's body with a permanent marker.


Conductive Adhesives, transient liquid phase sintering adhesives, Thermal Management

Our TLPS technology is ideally suited for device level thermal management of wide bandgap semiconductors, high brightness light emitting diodes, concentrator photovoltaics, hybrid electric vehicles, and RF power amplifiers. TLPS materials are also an alternative to conductive adhesives, with the added advantages of long-term contact stability and greatly enhanced thermal conductivity over a bondline, often by an order of magnitude or better.


Development Boards - Creative Electron

This stack can be composed of same type boards for performance improvement and resource sharing, or composed of multiple type boards. The STAR architecture combines scalability, flexibility, and performance in a compact 5x5in2 package. The STAR family of boards is the ideal Data Acquisition System for radiation detection applications. The shared communication bus enables the connection of multiple boards in a vertical stack.
