Silicon PIN diodes are used in radiation detectors to measure the intensity or spectral response of ionizing radiation. PIN diodes have a high sensitivity to various radiation types, such as X-ray, α- and β-particles, and can provide accurate readings with fast response times.
Advafab manufactures and supplies customer-specific Si PIN diodes. The design is defined together with the customer and our experts to reach the best possible performance for the manufactured diodes.Typically thin entrance window is implemented on the anode side of the diode to enhance the sensitivity of the diode for low energy radiation.
The performance of the Si PIN diode is typically assessed by leakage current, capacitance and energy resolution. Advafab is able to reach very low leakage current below 1 nA/cm2 with its fine-tuned process and usage of the best Silicon wafer starting material.
