Mar 01, 2013018332Highlights Grinding marks on silicon wafers are caused by the axial run out of the cup wheel. Grinding marks present multiple angular wavelengths characteristics. A grinding marks formation model was developed. An angular wavelength model of the grinding marks was developed. Grinding marks can be suppressed by reducing the cutting paths aggregation.
Optim Wafer Services has the ability to offer both wafer amp individual die grinding or thinning services for one off needs, volume production or prototype products. We are able to grind 100mm 300mm Silicon wafers down to 10181 and have demonstrated die thinning to 50um.
Wafer Grinding Once the vacuum chuck has been machined under controlled grinding conditions, the wafer can be mounted and ground. Since the wafer is very thin, its back surface conforms closely to the chuck surface. The front surface is then ground as flat as possible, again using real-time feed-back control and a ref-erence flat..

Oct 22, 2019018332Wafer grinding or backgrounding is the most popular method for thinning wafers. The dimension to which a wafer can be thinned depends heavily on the machine used, but most thin silicon wafers have around 50 micrometers thickness. Anything below that measurement put wafers at risk of suffering from reliability issues.
