To all,
        Thank you for all your replies. I omitted the word optically. I was
looking for
        equipment that can measure thick films more than 30um to 100um
optically. I would
        once again appreciate any directions I can have on it.

        I am looking for equipments that can measure thick resist more than 30
um
        upto 100um or more on silicon wafers. I would appreciate any directions
I
        can have on it.


Regards,

Padmaja
