Hi, Everybody:

                     Is there somebody who has some experience on controlling the thickness of sol-gel or etching sol-gel film? Thank you for your answer.

Regards!

hi xianjun,

i don't have personal experience but i read that to control sol-gel thickness, you can use the dip-coating technique..if you have a dipping apparatus or can fabricate one, then your work will be so much easier...by controlling the withdrawal speed, you can determine the sol-gel thickness

Hi xian,
You can etch your sol-gel film by plasma, the nature and intensity will mainly depends on the thickness of your film. You can control the thickness by the viscosity of your precursor and also a little on the spin coating rpm.

The thickness of solgel films can be controlled  by,
 
1.Dilute the solution (alcohol and water)
2.Lower speed on dip coater ( constant withdrwal rate)
3.Spray thin coat (spraying)
 
bye
