What it is
How it works
General reference — not yet source-verifiedA back grinder operates by using a rotating grinding wheel that contacts the backside of the wafer. The wheel is typically diamond‑embedded and removes material through a combination of abrasion and fracture. The wafer is held on a porous ceramic chuck by vacuum and rotated while the grinding wheel is lowered. Coolant is applied to control temperature and flush debris.
The grinding process often takes place in multiple stages: a coarse grind for bulk material removal and a fine grind to achieve the final thickness and surface quality. The machine can incorporate in‑process thickness measurement to control the grinding depth.
