Title: Gerard Destefanis: Innovator in Photodiode Technology
Introduction
Gerard Destefanis is a notable inventor based in Saint-Egreve, France. He has made significant contributions to the field of semiconductor technology, particularly in the development of photodiodes. With a total of four patents to his name, Destefanis has demonstrated a commitment to innovation and advancement in his field.
Latest Patents
One of his latest patents is for a CdHgTe photodiodes array. This innovative array includes a useful layer made of CdHgTe, with first doped zones forming a PN junction with a second doped zone surrounding them. The design features regions located between two PN junctions, characterized by a cadmium concentration gradient that decreases from the upper face to the lower face of the useful layer. The method of making this photodiodes array involves producing a structured layer on the upper face of the useful layer, which has a higher cadmium concentration. This is followed by annealing the useful layer, allowing for the diffusion of cadmium atoms from the structured layer. Additionally, he has developed a semiconductor structure capable of receiving electromagnetic radiation and transforming it into an electric signal. This structure includes a semiconducting support with a first zone of one type of conductivity and a second zone of the opposite type, forming a semiconducting junction.
