 +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
  
 Structure: 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 
-    * 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: "top_metal", "m2", or "delayered_right" 
-    * magnification: which objective was used.  See notes in "microscope objectives"

 +====== FAQ ====== 
 + 
 +Q: I want something imaged! How do I make that happen?
  
 +A: Consider sponsoring the site [[https://siliconpr0n.org/archive/doku.php?id=mcmaster:start#commissioning|by commissioning a chip project]]
  
-====== Microscope objectives ======+.
  
-Objective abbreviations +Q: I already have images. Can I add them here?
-  * 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.+A: Yes! Please reach out via contact info at https://siliconpr0n.org/ We can create you an account or you can give it to us to import

-====== SEM images ======+Q: Why use Dokuwiki and not Mediawiki?
  
-TODO: standardize SEM image naming.  There aren't enough images yet to make this important+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
