Partial Wafer Grinding is an efficient grinding method to process broken or damaged wafers, or wafer sections. This technique can be employed to process wafers that had been damaged, or wafer sections that are still intact, thereby avoiding loss of the entire wafer material.
May 01, 2006· The current production limit for grinding reduces wafers from an average starting thickness of 750 μm to as thin as 150 μm. Yield loss considerations from grinding and downstream processes (debonding from carrier) have made it very difficult to thin below 150 μm in production.
Fig. 2 illustrates the surface grinding process. Grinding wheels are diamond cup wheels. The workpiece (wafer) is held on the porous ceramic chuck by means of a vacuum. The axis of rotation for the grinding wheel is offset by a distance of the wheel radius relative to the axis of Fig. 4. Effect of wheel on grinding force and wheel wear rate.
Wafer Dicing Extremely High Processing Quality. Thin wafer dicing with extremely high processing quality, that is what customers have come to expect from GDSI. Dicing is the process by which individual silicon chips or integrated circuits on a silicon wafer are separated following the processing of the wafer.

iX-factory has in-depth expertise in wafer dicing. The video shows the process of wafer dicing in the state-of-the-art facilities of iX-factory.
Wafer Edge Trimming Wafer edge trimming is carried out using either a dicing or back grinding tool, both can handle up to 300mm diameter wafers and are fully automated. This service is normally required to remove the "knife edge" created when grinding and the subsequent thinning step of bonded wafers.
Due to the variation of wafer thickness during diamond grinding, the WTPM can be used to estimate the TTV after wafer thinning process. Experiments have been performed on a G&N nano grinder MPS-940 to demonstrate its feasibility of silicon wafer thinning.

Edge Grinding. Edge grinding, also known as Edge Profiling, is a process that is common to the manufacture of nearly all semiconductor related wafers and wafers that are used in the manufacture of many other electronic, solar, and nanotechnology devices. The edge grinding step is critical to the safety of the wafer edge.
Indium Phosphide Wafer Grinding. The EVG-250/300 series Vertical Grinding Machine combined with Engis MAD Grinding Wheels can achieve a superior surface finish on InP wafers to reduce or even eliminate loose abrasive lapping steps. The machine can be customized to your needs: Auto dressing; In process thickness measurement
Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC).. ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum .

The addition of the Stealth Laser Dicing® Process fortifies our line of mechanical saws, which has been the de facto dicing standard for decades. The Stealth concept is ideal for active surfaces due to its non-contact method of wafer separation, sparing the device layer from exposure to water, sawdust, mechanical shock and loss of real estate ...
stress relief process [5]. Figure 7 shows wafer bright field optical images for different CMP removal amounts after grinding ( (a) 0.2, (c) 0.5 and (e) 1 μm, respectively). For the case of 0.2 μm removal, the grinding marks are still distinguishable. It indicates that there is some grinding damage deeper than 200 nm. On the other hand, no ...
This is a die fabrication process in which, after the circuit surface has been half-cut, the wafer is made ultra-thin through back grinding while the die is diced. With an in-line system comprised of the Lintec's Fully-Automatic Multifunction Wafer Mounter (RAD-2510F/12Sa) and Disco Corporation's grinder, the risk of damage to wafers is reduced ...
