ISORG in Semiconductor Times


ISORG (Image Sensor ORGanic) was spun out of CEA LITEN (Grenoble, France) in May 2010 to develop and industrialize organic photodetectors and image sensors. ISORG is focused on technology for converting glass and plastic surfaces into smart surfaces able to capture information and react to it. ISORG's mission is "to develop and produce in high volume large area optical sensors for a wide range of markets." Large area organic photodetectors will be developed by strip integration of unit photodiodes. Large area organic image sensors will be developed using a matrix integration of rows and columns of unit photodiodes. Different pixel resolutions and matrix complexity will be addressed, depending on the application and market. The technology is based on new organic-conductor and semiconductor materials combined with large area, highvolume deposition and patterning equipment.

ISORG is using organic materials that are solution processable and are deposited at ambient temperature in different ways such as screen printing, spray coating, extrusion coating and inkjet printing. No vacuum-air processing is required. Plastic substrates will enable the design of flexible and conformable 3D sensors in any form factor. The sensors will be transparent, ultra thin, and lightweight. The photodetectors will have a large - and possibly selective - spectral response, ranging from visible (400nm - 700nm) up to Near Infra Red (NIR, 700nm - 1100nm) and higher. ISORG has a strategic R&D partnership with the CEA-LITEN, one of the most important research centers in Europe for New Energy Technologies and Nanomaterials, illustrated by more than 50 man-years activity and 25 patents. The company is also part of several committees working in Organic Electronics, Optical, Photonic and Electronics sectors.

ISORG intends to develop a range of products in low, medium or high resolution on both plastic and glass substrate for various applications and markets size. Examples include a large area, low resolution photodetector strip or matrix for industrial, environment, smart building, home appliances and toys markets; large area, medium resolution image sensors for industrial and consumer electronics markets; and large area, high resolution image sensors for medical market. The first functional prototypes are already available and an R&D pilot line is under construction at Grenoble. Development for the first customer has also started.
