{{stub}} '''Decapping''' (decapsulation) or delidding of an integrated circuit is the process of removing the protective cover of a microchip so that the contained die is revealed for visual inspection of the micro circuitry imprinted on the die. This process is sometimes necessary in emulation projects to copy information from [[Wikipedia:Digital_rights_management|DRM-protected]] ROM chips. Particularly [[MAME]] and other [[Arcade emulators|arcade emulators]] benefit from decapping projects.
Decapping is usually carried out by chemical etching of the covering, laser cutting, or mechanical removal of the cover using a milling machine. The process can be either destructive or non-destructive of the internal die. With care, it's possible to decap a device and still leave it functional.
==Decapping Groups==
Decapping Groups often rely on [[Support emulation projects|donations ]] to acquire hardware (ie arcade boards). [https://caps0ff.blogspot.com/ CAPS0ff] is the probably the biggest decapping group.
