Query: A study of silicon sensor for ILD ECAL   The International Large Detector (ILD) is a proposed detector for the
International Linear Collider (ILC). It has been designed to achieve an
excellent jet energy resolution by using Particle Flow Algorithms (PFA), which
rely on the ability to separate nearby particles within jets. PFA requires
calorimeters with high granularity. The ILD Electromagnetic Calorimeter (ECAL)
is a sampling calorimeter with thirty tungsten absorber layers. The total
thickness of this ECAL is about 24 X$_0$, and it has between 10 and 100 million
channels to make high granularity. Silicon sensors are a candidate technology
for the sensitive layers of this ECAL. Present prototypes of these sensors have
256 5.5$\times$5.5 mm$^2$ pixels in an area of 9$\times$9 cm$^2$.We have
measured various properties of these prototype sensors: the leakage current,
capacitance, and full depletion voltage. We have also examined the response to
an infrared laser to understand the sensor's response at its edge and between
pixel readout pads, as well the effect of different guard ring designs. In this
paper, we show results from these measurements and discuss future works.
