By using High-Voltage Ion Implantation, PREMA can offer several types of photodiodes with different spectral sensitivities. Unless stated otherwise, photodiodes are type I.
Because all in semiconductor industry common fabrication techniques are available, photodiodes can be closely packed next to each other. (Arrays of photodiodes)
For applications using higher frequencies, a special type of photodiodes with reduced capacitances (< 25 pF/mm²) is available. Very low dark current with less than 100 pA at reverse voltages of 10 V can be achieved.
