Abstract
e2v technologies has developed "Hi-Rho" devices manufactured on very high resistivity silicon. Special design features have been included that enable extremely high gate to substrate potentials to be applied without significant current leakage between back and front substrate connections. The approach taken allows the usual design rules for low noise output amplifier circuitry to be followed. Thus low noise devices very sensitive to red and near infrared wavelengths can be manufactured. This paper reports on the detailed characterisation of the large format "Hi-Rho" sensor designed for astronomical applications and extends the data previously reported to include detailed assessment of the CTE, spatial resolution, dark signal and cosmetic quality. The influence of the base material has also been investigated with devices manufactured on silicon from two different manufacturers. Measurements of the quantum efficiency from devices utilising a newly developed antireflection coating process are presented.
