KP-M monitor photodiodes are used to monitor the laser output of optical communication equipment.
Higher quality devices are required as the expansion of digital transformation and 5G communications progresses. The "KPDE008LS-A-RA-HQ" has achieved higher quality by adding the probing process at higher temperature.
A new wafer prober*1 has been introduced to inspect the electrical characteristics of semiconductor wafers while heated to high temperatures. This allows the inspection to test the temperature (T=75℃) close to the absolute maximum rated value of the operating temperature of the product. Since the full inspection is implemented to wafers with this prober, higher quality products under higher temperatures can be realized.
Then the sample inspection is conducted by wafer and the sampled products are sent to the burn-in test. The samples are heated up to the high temperature of 175℃ and their performance are inspected. If any of the sample products does not meet the standard, all the products on the same wafer are not shipped. This screening by wafer enables us to offer higher quality products.
Mass production of the KP-M monitor photodiode "KPDE008LS-A-RA-HQ" is scheduled to start on December 1, 2021.
