Reliability issues in solid state lighting (SSL) devices based on light emitting diodes (LED) is of major concern as it is a limiting factor to promote these optoelectronic devices for general lighting purposes. This postulate is even truer for high power devices in which high current and thus high thermal load are involved. In order to increase reliability(More)
— Recently applying an intelligent self-curing system to get a feedback from the LED light in order to control its intensity with driving current has attracted so much attention. This study presents a silicon stripe-shaped photodiode which is successfully designed and fabricated using a 2μm BiCMOS process. This process flow integrates simultaneously the(More)
