Last weeks since I've seen Francois's images I'm trying to capture my CPU's dies.
Equipment that I already had:
SLR camera 28-90mm 35mm eq.
CCD matrix scanner
several lenses
I was really disappointed 
Here are the "best" images I've got:

After that I decided to buy stereomicroscope like g0b has 
I visited local optic commission shop.
There were alot of microscopes at the price of $50...$1000.
The seller patiently listen to me...
And then he surprisingly offered me to buy old film camera objective lens for $3
He said I have to attach it to my camera lens "face to face"
I was thrilled by the first image I made in this way

You don't need any special type of lens. Just buy an old manual lens (with M42 mount for example) and connect it to your main leins with an coupling adaptor.
A coupling adaptor can be purchased in a photo accessory shop.
Here is an extract from Wikipedia
http://en.wikipedia.org/wiki/Macro_photography
| Wikipedia wrote: | | Reversing a lens of lesser focal length in front of a normally mounted lens using an inexpensive "macro coupler," which screws into the filter threads on the front of the two lenses to join them mechanically. This method allows most cameras to maintain the full function of electronic communication with the normally mounted lens for features such as open-aperture metering. Magnification ratio is calculated by dividing the focal length of the normally mounted lens by the focal length of the reversed lens (e.g., when an 18 mm lens is reverse mounted on a 300 mm lens the magnification ratio is 16:1). The use of automatic focus is not advisable as the extra weight of the reverse-mounted lens could damage the autofocus mechanism. Working distance is significantly less than the original lens. |

It's a die of U80701 (I had missed pin chip and I decided to open it)

Compared to this DEC DC333 only bondout pads look different:

That lasy shot looks like a small city on google earth .
Very nice and clear , great job.  there nothing like tinkering around to see what works well with what you have handy.

| Thanks for sharing Igor! I'll have to check this out. I have been trying to do die shots with a scanner which doesnt work so well. It's possible but you have to manage some massive files. |

Very nice Igor, excellent result!
William Blair who made a lot of chipdie-photography
also uses the reversed objective lens method.
http://www.cpu-world.com/info/die_pictures.html
I think it is 2nd best method for the lowest price!
The best method (gaining the highest quality) would be using
an expensive extension bellows combined with an
even more expensive hiend macro/micro-lens with fixed focal length.

Can you post a picture of this lens and the camera it attaches to?
I'm ready to try this and post my dies!
On a related topic, has anyone heard of a way to mechanically convert a 35mm film camera, like a Canon FT-QL, to a digital format? I have a great set of lenses with this old camera and I'd like to know how to use them for Micro-photos!  |

Blair's site is here with the information of his setup:

Be careful.. from what I see on other websites, taking pictures of the World in very small detail becomes very addictive ( and expensive? ) |
