The Silicon Archive is a collection of practical integrated circuit and general electronics information. Most of it is manifested as die shots.

High resolution chip maps

As of 10/6/2014 there are 149.

Linked from pages when available and can be found at: Tiles were originally output at .jpg quality 75 but since upgrading pr0n disk space in early 2013 tiles should now uploaded at .jpg quality 90.

Original images used to generate tiles can be found interspersed with the tiles. Sometimes these are not available for one reason or another but in any case can be reconstructed from the map tiles (most likely at some loss of quality) by running something like “montage -geometry +0+0 -tile 73×60 *.jpg out.png”. The raw tiles can be found in “tiles_out” sub-directory


  • First level contains vendor name (short forms like “ti” preferred over Texas Instruments)
  • Second level contains chip name. Ideally should have enough information to determine exact mask. Ultimately an Archive wiki pages should link to the map to provide canonical details by showing a package or device image
    • Chip name should match the wiki page name
  • Next level should contain files of form <layer name>_<magnification> where
    • layer name: short description of the area imaged. For example: “mz”, “m2”, or “delayered_right”.
    • magnification: which objective was used. See notes in “microscope objectives”

Example: “ti/tl494a/mz_mit5x”

  • ti: most associated with Texas Instruments (either made by, designer, or simply the most prominent package markings)
  • tlm494a: chip name including revision
  • mz_mit5x: layer name and magnification


Q: I want something imaged! How do I make that happen?

A: Consider sponsoring the site by commissioning a chip project


Q: I already have images. Can I add them here?

A: Yes! Please reach out via contact info at We can create you an account or you can give it to us to import


Q: Why use Dokuwiki and not Mediawiki?

A: ACLs are required for certain projects that can't yet be made public. Dokuwiki supports this much better than Mediawiki which is either fully closed or fully open
