Scanning modes range from sin- gle layer views to tray scans and cross-sections. Multilayer scans can include up to 50 independent layers. Depth-specific informa- tion can be extracted and applied to create two- and three-dimen- sional images without the need for time-consuming tomographic scan procedures and more costly x-rays. The images are then ana- lyzed to detect and characterize flaws such as any irregularities in the thickness of the ESC’s dielectric layer as well as minis- cule cracks and pores. Companies like OKOS offer a


range of SAM products from com- pact, tabletop units to fully auto- mated production line systems.


High Throughput When high throughput is


required for 100% inspection, ultra-fast single or dual gantry scanning systems are utilized along with 128 sensors for phased array scanning. Multiple transducers can also be used to simultaneously scan for higher throughput. As important as the physical


and mechanical aspects of con- ducting a scan, the software is critical to improving the resolu- tion and analyzing the informa- tion to produce detailed scans. Multi-axis scan options enable A, B, and C-scans, contour following, offline analysis, and virtual res- canning for ESCs, which result in highly accurate internal and external inspection for defects via

the inspection software. Various software modes can


be simple and user friendly, advanced for detailed analysis, or automated for production scan- ning. An offline analysis mode is also available for virtual scanning. “OKOS decided early on to


deliver a software-driven, ecosys- tem-based solution,” says Polu. The company’s ODIS acoustic microscopy software supports a wide range of transducer fre- quencies from 2.25 to 230 MHz. Polu estimates that the soft-


ware-driven model enables them to drive down the costs of SAM

testing while delivering the same quality of inspection results. As a result, this type of equipment is well within reach of even modest testing labs, R&D centers, and material research groups. “Every semiconductor fabri-


cator will eventually move towards this level of inspection for ESC quality control because the level of detection is far supe- rior to conventional methods. The increased accuracy, reliabili- ty, and comprehensiveness as well as decreased cost and time involved are driving the change.” concludes Polu. When fabricators take
