Abstract
The invention relates to a planar photodiodeincluding a detection portionmade of a germanium-based material M, and a peripheral lateral portionincluding several materials stacked on top of one another, including a material Mhaving a coefficient of thermal expansion lower than that of the material M, and a material Mhaving a coefficient of thermal expansion higher than or equal to that of the material M. The intermediate regionincludes a portion Psurrounded by the material Mand having tensile stresses. It also includes a portion Psurrounded by the material Mand having compressive stresses. This portion Psurrounds a n doped box
