Samsung patents machine that marks chips with pressure sensors
Samsung has filed a patent for a machine that marks substrates, which are thin sheets used in electronics manufacturing. The device uses a camera and marking tool on a moving arm, along with a pressure sensor to ensure the tool touches the surface correctly.
In the filing’s own words
Provided is a substrate marking apparatus. The substrate marking apparatus includes a stage configured to support a substrate, a camera-marking assembly on the stage, movement devices configured to move the camera-marking assembly, and a controller electrically connected to the camera-marking assembly and the movement devices, wherein the camera-marking assembly includes a main body connected to the movement devices, a marking device adjacent to the stage, and a pressure sensor coupled to the main body.
What exactly they claim (claim 1)
1. A substrate marking apparatus comprising: a stage configured to support a substrate; a camera-marking assembly on the stage; movement devices configured to move the camera-marking assembly; and a controller electrically connected to the camera-marking assembly and the movement devices, wherein the camera-marking assembly comprises: a main body connected to the movement devices; a marking device adjacent to the stage; and a pressure sensor coupled to the main body.
