This is an old revision of the document!
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
Linked from pages when available and can be found at: http://siliconpr0n.org/map/ 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.
Upon request the original images can be found at: http://siliconpr0n.org/single/ These can also 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”
Structure:
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
Next level should contain files of form <layer name>_<magnification> where
layer name: short description of the area imaged. For example: “top_metal”, “m2”, or “delayered_right”
magnification: which objective was used. See notes in “microscope objectives”
Example: “ti/tl494a/top_metal_mit5x”
ti: most associated with Texas Instruments (either made by, designer, or simply the most prominent package markings)
tlm494a: chip name including revision
top_metal_mit5x: layer name and magnification
Microscope objectives
Objective abbreviations
bli20x: Bausch & Lomb industrial 20x (designed for streozoom series)
ch2x: cheap supposedly Apo 2x objective that may be made of soda glass (green tinge…). Loosely resembles Seiwa objectives
mit5x: Mitutoyo M Plan Apo 5x
mit10x: Mitutoyo M Plan Apo 10x
mit20x: Mitutoyo M Plan Apo 20x
mit100x: Mitutoyo M Plan Apo 100x
neo5x: Olympus Neo 5x
ns50x: Olympus Neo SPlan 50x
ns50xu: Olympus Neo SPlan 50x ultra-long working distance (ULWD)
NOTE: typically involves 10x relay lens to make actual magnification times 10. For example, a Mit20x objective is used with a 10x relay lens to make the final image at 200x magnification on the CCD. However, chip pages should specify net die size if actual size is important as sensor size has no relation to pixel size, especially in stitched images.
SEM images
TODO: standardize SEM image naming. There aren't enough images yet to make this important
azonenberg's semi-standard is as follows: foo_20kV_2kx_3e-11a_15mm_ap4_se_01.jpg
Sample “foo”
20kV accelerating voltage
2000x magnification
3e-11A probe current
15mm working distance
Aperture #4 (actual size depends on the specific instrument in use)
Secondary electron image (other legal values are “bse”, “eds”)
Image number 1 of the set
