Mornin' Inge ol' buddy!

Your chart is up! Go to: http://www.stevezeva.homestead.com and
click on Picture Page 2, then look for "Etchant Chart".

This chart has made me break out the Periodic Table of Elements.
I know a lot of the symbols, but not all of them on the chart...hehehe.

Kind regards,

Hi, have an old but good reaction chart for material etching. But I miss
soups for the bottom materials like GaAs and TiN and others which are used
for the wafer processes. Does anyone have an update on those with no
crosses on the map?

Steve, know you have just began on page two, plenty of space then. Do you
mind hanging my etchmap?
