SWIR Time of Flight (TOF) Pixel Design

PhD - Leuven | About a week ago

The future is TOF! 

Introduction 

 Thanks to the artificial intelligence revolution, digital photography witnesses a paradigm shift from simply taking pictures to sensing specific information. Among those sensing applications, TOF has been most successful by being adopted in the consumer electronics widely. However, its usage is limited to short distance detection because of the insufficient performance in the longer range. Active illumination in SWIR (short-wave infrared, with wavelength above 1.4 um) has advantage over NIR (near infrared, with most used wavelengths below 1 um) due to less ambient light and better eye safety, eventually can be used to achieve longer working distance TOF. Based on our strong expertise in designing with and processing foreign materials which can effectively detect SWIR, imec strives to be at the forefront these new developments. 

 

Topic 

The goal of this PhD is to develop SWIR TOF image sensor technology. This research starts from material and device structure understanding via literature studying and TCAD simulation. Actual design/layout of the SWIR TOF image sensor using novel device structure and state of the art processing follows. Eventually, evaluation and analysis in different perspectives with a technology demonstration will be key.
