A silicon-tungsten electromagnetic calorimeter with integrated electronics for the International Linear Collider

We present an update of the development of an electromagnetic calorimeter for the Silicon Detector concept for a future linear electron-positron collider. Mechanical progress for a full barrel calorimeter that provides a more complete basis for simulation is discussed. Crosstalk problems in the first version of the sensor were found in a first testbeam study, and a second version of the sensor is now beginning testing.
