Latest Patents
John T Peurach holds a patent for an "Automatic calibration system for wafer transfer robot." This system is designed to automatically calibrate a semiconductor wafer handling robot, ensuring that it can accurately move wafers into and out of precise locations within enclosures that form process stations or storage cassettes. The system includes a controller with memory and logic sections connected to a robot equipped with an articulated arm. This arm is capable of movement in vertical, horizontal, and radial directions, and it features a wafer retaining wand at its end. The controller's memory stores the dimensional characteristics of both the robot wand and the enclosures. Sensors at each enclosure and/or the robot wand provide signals to the controller that relate to the wand's position. The robot is programmed to execute a series of movements at each enclosure location, guided by sensor responses and dimensional characteristics. Ultimately, the robot wand is positioned within a process station or cassette to engage and release wafers at precise predetermined locations.
