Excess Noise in GaAs Avalanche Photodiodes with Thin Multiplication Regions

It is well known that the gain–bandwidth product of an avalanche photodiode can be increased by utilizing a thin multiplication region. Previously, measurements of the excess noise factor of InP–InGaAsP–InGaAs avalanche photodiodes with separate absorption and multiplication regions indicated that this approach could also be employed to reduce the multiplication noise. This paper presents a sys...

Parametric Manufacturing Yield Modeling Of GaAs/AlGaAs Multiple Quantum Well Avalanche Photodiodes - Semiconductor Manufacturing, IEEE Transactions on

GaAs/AlGaAs multiple quantum well (MQW) avalanche photodiodes (APD’s) are of interest as an ultra-low noise image capture mechanism for high-definition systems. Since literally millions of these devices must be fabricated for imaging arrays, it is critical to evaluate potential performance variations of individual devices in light of the realities of semiconductor manufacturing. Specifically, e...
