Abstract:
1. An electron sensing device for receiving electrons from an output surface of an electron gain device, the electron sensing device comprising: a silicon die including an active surface area for positioning below the output surface of an electron gain device, wherein the silicon die includes a silicon step formed below and surrounding the active surface area, and a first array of bond pads formed on the silicon step for providing output signals from the silicon die, wherein when the electron sensing device is positioned below the electron gain device, a tight vertical clearance is formed between the output surface of the electron gain device and the active surface area of the electron sensing device, and an array of terminals disposed on a periphery of the active surface area of the silicon die, and an array of conductive stripes extending between the array of terminals and the first array of bond pads, wherein each conductive stripe includes an end terminating at the first array of bond pads positioned below another end terminating at the array of terminals.
