On a different die one can see funny litho/processing defect over power transistor (especially at full resolution):


Wafer also had few test chips:


That was on 3" wafer:


Thanks for the original wafers to Bob Miller, one of the designers of this chip.]]>

<![CDATA[Silicon Labs Si8641 - quad channel digital isolator : weekend die-shot]]> http://zeptobars.com/en/read/SiLabs-Si8641-digital-isolator Silicon Labs Si8641 uses capacitive coupling to implement digital isolation (up to 5kV, this model 2.5kV) as speeds of up to 1 Mbps.
This particular model (Si8641AB) contains 2 identical dies, apparently configured by bonding some of the pads on the sides.
