One of the most important features of a camera is the dynamic range. It expresses the capability of a camera to capture the light range between the brightest and darkest areas in a scene without overexpose or underexpose them. Thus, the higher the camera’s dynamic range the greater the contrast between lights and darks areas can be captured without losing details. The OmniVision is bringing TheiaCel™ technology developed for automotive image sensors to improve the high dynamic range (HDR) to advance mobile imagers. OmniVision’s TheiaCel™ technology incorporates lateral overflow integrated capacitors (LOFIC) and triple conversation gain (TCG) HDR technology to achieve human eye-level HDR with single exposure in standard mode.
The OV50K40 (known as OV50K) CMOS image sensor (CIS) is a 50 MP, 1/1.3” format, stacked back-illuminated (BI) CIS with a pixel pitch of 1.20 µm. It is the first mobile image sensor to use the TheiaCel™ technology.
This report provides an overview into the structure of the OmniVision OV50K CIS. The analysis provides foundry identification and details of the fabrication process used to manufacture the image sensor and image signal processor (ISP) and a summary of the salient features observed, and is accompanied by a set of optical, SEM cross-section, and bevel images of both CIS and ISP dies. The pixel schematics and layout information are also included in the report. The structural and process information in this report is of interest to image sensor designers and architects, technologists, foundries, equipment suppliers, and all parties linked to the image sensor development.
