Request InfoFirst Sensor Inc.Pacific Silicon Sensor Inc. has developed a method to produce flip-chip photodiodes with both contacts on the same face, allowing the device to have a front face without bond wires or other contact areas. The process moves aluminum from the front face to the rear under a controlled temperature gradient by a conductive channel of P-type material. The technology is available for 4-in. N-type silicon wafers in the resistivity range up to 50 (omega)-cm.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2023 IssueHand-Held Gas Detection CameraThe Handheld Optical Gas Imaging Camera from MFE Inspection Solutions visualizes harmful gas leaks in real-time for immediate action.
