Latest Patents

One of Frank Fehrmann's latest inventions is a semiconductor inspecting method designed to ensure the scrubbing length on a pad. This method consists of several key steps. First, a probe needle's initial position is defined from above. Then, a wafer containing at least one pad is placed on a wafer chuck within a semiconductor inspecting system. By employing the driving system of the inspecting system, a relative vertical movement between the probe needle and the pad is initiated to generate a scrubbing length. The system then recognizes whether this length meets or exceeds a preset value, and consequently, the relative movement is halted using the driving system. This innovation promises to enhance precision in semiconductor manufacturing processes.

Another notable patent involves a similar semiconductor inspecting method, where the procedure begins with defining a probe needle’s initial position through a vision system. Following this, a relative vertical movement is produced, and a minimum positional change of the probe needle is detected by the vision system, ultimately leading to a controlled cessation of movement.
