Hybrid pixel detector development for the linear collider vertex detector

In order to fully exploit the physics potential of future high energy e⁺e^- linear collider, a Vertex Detector providing high resolution track reconstruction is required. Hybrid silicon pixel detectors are an attractive option for the sensor technology due to their read-out speed and radiation hardness but have been so far limited by the achievable single point resolution. A novel layout of hybrid pixel sensor with interleaved cells to improve the spatial resolution has been developed. The characterisation of the first processed prototypes is reported
