Dear Thermco useres, 
I ran 9 wafers in tube 1 WET1000 35min, I had run this recipe 8 times in nthe past year and the thickness is always 3000A, when I ran the same recipie today I got 2000A, has anyone changed any parameter in the recepie or ran any unsual recipe on thermco 1 recently? 

Thanks, 
Arash
