Overview. Semiconductor technology has been growing rapidly due to new wafer manufacturing technologies, advances in simulation and MEMS and nano manufacturing.In the semiconductor industry, thinning of silicon wafer is carried out by fine grinding and polishing. Other electronics apparatus such as PCB manufacturing technology also have grown significantly with challenges in
Wafer Edge Grinding Machine. The Specialized Wafer Edge Grinding Machine. Semiconductor wafer grinders Many companies have developed several types of grinding machines used in the semiconductor industry for the production of silicon wafers and the production of integrated circuits
A grinding wheel 150 applies pressure, noted with bold force vector arrow P, vertically to back side 24 of semiconductor wafer 20 during a back-grinding process that removes excess substrate. In some embodiments, the chuck table 110 and grinding wheel 150 spin simultaneously in the same direction (i.e., both in a clockwise or counterclockwise
A method for manufacturing a low profile semiconductor chip, includes fabricating a semiconductor device on a semiconductor wafer, grinding, with a grinding tool, a backside of the semiconductor wafer to reduce a thickness thereof, and with the wafer in the grinding tool, providing a support structure on the ground backside of the wafer

Back Grinding Machines In Semiconductor Wafer grinding also called wafer thinning is a process performed during the semiconductor manufacturing to reduce wafer thickness This manufacturing step is essential in producing the ultrathin wafers required for stacking and highdensity packaging in portable and handheld devices
Semiconductor Back-Grinding The silicon wafer on which the active elements are created is a thin circular disc, typically 150mm or 200mm in diameter. During diffusion and similar processes, the wafer may become bowed, but wafers for assembly are normally stress relieved and can be regarded as flat
A typical two-step backgrinding operation uses twin spindles with grinding wheels mounted on each spindle. Wafer scratches and strength. After back grinding, the wafer will have a scratch pattern on the back side. The depth of these scratches will depend on the grain size of the wheel and the amount of vertical pressure exerted during grinding
The back-end process: Step 3 – Wafer backgrinding. BY EDWARD G. COMBS. With the proliferation of smaller and thinner packages for portable and hand-held products, there is an increased need for thinner semiconductor devices. What used to be a process for only selected situations is now a required process for most applications, and the technology for thinning wafers is becoming more critical than
The capability to quickly and efficiently produce quality wafer surfaces in pilot line and R & D applications is key in today’s rapidly changing semiconductor environment. The engineers at Engis have developed a grind straight to polish process to meet these challenges for most compound semiconductor materials should that be bulk wafer or back thinning applications
