Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching.

Wafer Backgrind Wafer Backgrind is the process of grinding the backside of the wafer to the correct wafer thickness prior to assembly. It is also referred to as ''wafer thinning.'' Wafer backgrinding has not always been necessary, but the drive to make packages thinner and thinner has made it indispensable.
Wafer polishing is a silicon wafer finishing process used to create a stronger, thinner, and more flexible silicon wafers. The wafer polishing process creates thinner wafers than backgrinding alone, and removes stresses and prevents warping that causes wafers to weaken.
Oct 24, 2019· A doubleside polish wafer is extremely flat, particlefree, and has a mirrorlike surface. To achieve this, wafers need to go through the process of polishing, specifically chemical mechanical polishing. CMP involves the use of chemical and mechanical action to weaken the atomic bonding of the wafer surface and to aid in material removal.
Backgrinding is the process of removal of silicon from the back of wafers following conventional semiconductor processing. The process is primarily utilized in thinning wafers for commercial semiconductor wafer fabs. Wafers are first laminated using an automatic taping machine. After inspection, they are placed on a Disco 84X series infeed grinder.

After the wafers have been sliced, the lapping process begins. Lapping the wafer removes saw marks and surface defects from the front and backside of the wafer. It also thins the wafer and helps to relieve stress accumulated in the wafer from the slicing process. After lapping the silicon wafers, they go through an etching and cleaning process.

Jan 15, 2013· Silicon dies are separated from the wafer via a dicing or sawing process. Typically, wafers coming out of the foundry are approximately 750um thick to ensure maximum robustness during shipping. Before dicing wafers typically go through a back grinding (or backgrinding) process to thin down wafers to 75um to 50um.
Thin Wafers. Grinding thin wafers (less than 150 um) on an old grind tool model may not be a great pleasure. Either an extra process step (etching) may need to be introduced or a new capital investment needs to be made to improve the yields.
