Forza’s Integrated Production Services Get Hands-on Yields for Rear Light Sensors


PASADENA, Calif.–(BUSINESS WIRE)–Forza Silicon, an AMETEK company and leader in advanced designs of image sensors and mixed-signal ICs for imaging applications, recently used its Integrated Production Services (IPS) to enable production high-speed image sensors that use back-side illumination technology (BSI).

Although BSI sensors have been available for more than 10 years in many standard mobile phones and digital cameras, the manufacturing process is inherently more difficult than comparable Frontal Illumination Sensors (FSI) because it requires additional manufacturing steps . The realities of semiconductor economics have also made it difficult to transfer technology from the high production volumes of standard cameras to the lower volumes of high-speed imaging sensors.

Overcoming these issues, Forza leveraged its IPS capabilities to optimize the BSI sensor manufacturing process and achieve practical yields.

“These internal services include wafer prototype and probe development, qualification services, yield optimization, as well as production testing and delivery,” said Loc Duc Truong, vice president of engineering. at Forza Silicon. “Together, these capabilities have allowed us to overcome the manufacturing challenges associated with BSI sensors.”

The high-speed BSI sensor design is the result of a collaboration between Forza Silicon and Vision Research, a leading manufacturer of high-speed digital imaging systems. By designing the photoactive area on top of the circuit, the sensor increases the pixel area that can capture photons under low light conditions, bringing two significant benefits to high-speed applications: improved fill factor and faster improved treatment.
