Hello,
I’m simulating a Medipix3 detector which I have which does not have any metallization on the backside. The implant itself forms the ohmic contact. I’m using a modified version of the default medipix3 model, but I’m not totally sure if I’m setting it up correctly. The sensor is 100um thick silicon. This is the config file I have for the model:
type = “hybrid”
geometry = “pixel”
number_of_pixels = 256 256
pixel_size = 55um 55um
sensor_thickness = 100um
sensor_excess = 1mm
sensor_material = “silicon”
bump_sphere_radius = 9.0um
bump_cylinder_radius = 7.0um
bump_height = 20.0um
chip_thickness = 100um
chip_excess_top = 1610um
chip_excess_bottom = 1610um
chip_excess_right = 10um
chip_excess_left = 10um
[support]
thickness = 1.76mm
size = 47mm 79mm
offset = 0 -22.25mm
It’s effectively the same as the default medipix3.conf, but I have changed the sensor thickness and removed the following bit of code:
[support]
thickness = 5um
size = 14.08mm 14.08mm
location = “sensor”
material = “aluminium”
If I understand correctly that is what defines the metalisation on the backside of the sensor? Any help would be appreciated.
Cheers,
Rory
