LTO coverage in deep trenches

Hello All,

I am trying to find out if LTO has good conformal coverage in deep trenches. I have straight trenches are 30 um wide, and about 275 um deep, in a silicon wafer. I plan to deposit 0.5um LTO as an insulation layer over the side walls. Will this work? Your input will be highly appreciated.

Subject: 6" wafers?

Hello All, 

I have need for a total of three 6” wafers, and was wondering if anybody had any ‘extras’ they’re willing to share.  They are merely serving as a carrier for my samples which will be getting irradiated with cesium ions from an outside vendor.  I therefore do not care what the doping, resistivity, or thickness is, or even if there are oxide or nitride or other layers on top.  I only need full (non-broken) 6” wafers. (Heck, they don’t even have to be silicon, I don’t think.)  If anybody has any, I’d be much obliged.  Thanks,
