Business Wire: Science and Technology Facilities Council’s (STFC) Rutherford Appleton Laboratory (RAL) and TowerJazz have developed 120mm x 145mm X-Ray sensor wich is said to effectively use an entire 200mm wafer. The sensor's focal plane has a size of 139.2 x 120 mm, and has 6.7MP resolution (2800 x 2400 format) with a 50um pixel pitch, 32 analog outputs and also features low noise, a high DR and a programmable region-of-interest readout. Each 3T pixel has low-noise partially pinned photodiode, offering ‘charge-binning’ capability. The sensor offers a very high frame rate of 40fps at full resolution and ‘binned’ images can be read at an increasingly faster rate.
The device has sensing pixels right up to the edges on three sides of the imager. This allows multiple sensors, manufactured on cost-effective 200 mm silicon wafers, to be ‘butted’ or ‘tiled’ together in a 2 x 2 arrangement to form a significantly larger imaging area and to meet the requirements for mammography applications. Additionally, any 2 x N sensor arrangements are possible, thus making the device ideal for applications that demand even larger area coverage, such as chest imaging or security scans.
Tanner is also announcing that the project relied exclusively on its tools.
