A variety of services are offered by wafer dicing companies. Some of these services embrace die dicing, plasma dicing, and scribing. This text will talk about these choices and the way they may help you create the perfect merchandise. For extra info, contact the companies listed under. Additionally, make sure to ask about their high quality management procedures. Some companies even provide their prospects a assure of their work, if you happen to are not glad with their work.

Die dicing

Die dicing for semiconductor wafers is a extremely specialised course of that yields squares, rectangles, and straight strains. The width of the road, which is the dimensions of the squares left on the tape, is dependent upon a number of variables, together with the blade thickness and the diameter of the wafer. Controlling a number of variables will assist produce probably the most exact outcomes. Die dicing is used within the manufacturing of semiconductor gadgets akin to reminiscence chips, built-in circuits, and photovoltaic modules.

The dicing mechanism consists of a rotating blade that crushes the substrate materials. The blade is made of diamond grit embedded in an electroplated nickel matrix. The blade strikes from one lively space of the die to the opposite alongside devoted dicing streets. The blade creates a groove within the substrate materials because it passes alongside the streets. The width of the groove is straight proportional to the blade thickness.


The current invention pertains to a way and equipment for scribing a semiconductor wafer. First, a plurality of boundary segments are fashioned on the wafer, every area comprising an digital system. Then, a portion of the insulating layer is eliminated, exposing the scribe strains. The scribe strains then separate the digital gadgets from the wafer whereas minimizing injury to them.

The scribing course of makes use of blades to chop a groove in a wafer. Usually, this methodology is used for wafers lower than 6 inches in diameter. At this time, nonetheless, scribing is used for wafers as much as 300um thick, and has excessive throughput and accuracy. It additionally doesn’t chip the wafer. Whereas this methodology is mostly used for uncoated wafers, scribers are additionally accessible for metallic coated SiC and DBR coated sapphire wafers.

Plasma dicing

Wafer dicing might be executed with two fundamental strategies: sawing and scribing. The latter is most popular for skinny wafers, whereas the previous is used for wafers greater than 10 mil thick. The wafer is pre-aligned and mapped earlier than dicing. Then, the wafer is mounted on the dicing tape from the bottom. To finish the dicing course of, the entrance facet is eliminated, whereas the bottom is mounted on the dicing tape.

Whereas plasma dicing is low-temperature and low-stress, it’s much less correct than laser dicing, requiring masking for non-etchable areas and lowering throughput. Plasma dicing means that you can take away guard rings and use extra wafer real-estate to design a chip. This lets you take away guard rings and make the most of wafer real-estate for different lively dies.

Conventional blade dicing

Dicing for wafers is a typical semiconductor manufacturing course of. The method begins with mounting the wafers on adhesive movie and positioning them inside a metallic body. Engineers then place the wafer and body in a chuck. To slice the wafer, the diamond blade is turned between 15,000 and 30,000 RPM. A cooling agent is sprayed alongside the reducing strains to manage temperature and forestall contamination by the noticed blade.

Dicing tape is used to mount the wafers. The tape has an adhesive backing, which helps the wafer stay steady through the course of. The tape then holds the wafer in place, which is then moved into the dicing noticed’s chuck. After the dicing is completed, the wafer is thinned, however this may trigger issues akin to wafer cupping and bowing, making scribing troublesome. Nevertheless, if the wafer is thinned previous to dicing, these issues could also be much less widespread.

Simac wafer dicing

Simac provides customized dicing and reducing procedures for semiconductor producers. Usually, semiconductor producers want to make use of a selected blade or set-up for particular functions. Simac may help these companies with this course of and assist them obtain greater profitability. As well as, we may help you choose the correct tools and blades in your dicing and reducing processes. Simac’s skilled technicians can help you within the choice course of and supply detailed technical recommendation.

Wafer dicing services are essential for semiconductor manufacturing, as a result of they separate particular person die from semiconductor wafers. The method sometimes requires various blade thickness and supplies to create particular person cube. These dies are then packaged into particular containers, like waffle packs or gel-paks. Simac’s skilled scribes could make correct cuts that reduce chipping, so that you might be assured of top-quality outcomes. When you want a customized wafer dicing service, contact us at the moment to study extra about our dicing services.
