Toshiba shrinks solid-state lidar for transport infrastructure

Toshiba has updated its solid-state lidar, claiming the world’s smallest physical volume. A key improvement is within the silicon photo-multiplier (SiPM) light receiving integrated circuits which have light-receiving cells controlled by transistors. The new chips have smaller transistor modules, replace buffer layers protecting the transistors with newly-developed insulating trenches between the transistors and the light-receiving ...
