Wafer Coring Services

Wafer Coring Services involves reducing the diameter of the wafer so that it fits into the available processing equipment. This process is a great way to save time and money.

A silicon wafer is a circular slice of semiconductor material that is used in the manufacturing of integrated circuits and other electronic devices. It has a diameter that can range from 25mm to 300mm wafer dicing services in size.

Resizing

A wafer is a thin layer of semiconductor material that manufacturers use to create integrated circuits (ICs). Many different processes are used in the manufacturing of ICs, each with its own unique requirements for how a wafer is handled during processing.

One of the most basic needs is to resize a wafer so that it fits into the available processing equipment. This can be done in a number of ways.

Resizing is particularly useful for a company that has expensive process tooling designed to handle a particular wafer size. As wafers get larger and larger it becomes more difficult to fit them into the tooling, requiring replacement of the tooling or resizing the tooling down to work with the new wafer size.

Crystal Mark's SWAM(r) C-5100 replaces all grinding operations with a numerical, computer-controlled, micro abrasive nozzle positioning system that resizes the wafer without creating excessive heating or a significant effect from shock to the wafer. It is ideal for Cutting and Edge Rounding of silicon, sapphire, Geranium, NaG, GaAs, and other III-V materials as well as for Epi Crown Removal.

Dicing

The dicing process involves breaking a wafer down so that it fits into the available processing equipment. Dicing can be done by mechanical sawing, laser dicing or waterjet dicing.

Stealth dicing is another method that uses a laser to make perforations in a “stealth” layer beneath the surface of the wafer. This reduces the chance of chipping while allowing for the creation of die streets that are typically 75 micrometers wide.

Unlike laser dicing, stealth dicing does not create heat and does not require cooling agents. This makes it ideal for a variety of materials including silicon, gallium arsenide, aluminum, boron nitride, glass, InSb, Lithium niobate, PZT and quartz.

Several parameters affect a dicing blade’s performance, including cutting depth, spindle speed, feed speed and cutting angle. In this study, we analyzed the effect of these factors on the radial wear, maximum spindle current and surface morphology of SiC wafers after dicing with a metal-bonded dicing blade at different feed speeds.

Scribing

Wafer coring involves reducing the diameter of a wafer so that it fits into the available processing equipment. This process is often used in the manufacture of integrated circuits or semiconductors.

The scribing process is an effective way to separate chips on a wafer. It uses a scribe line to create a stress concentration factor on the wafer that makes it break along this line after applying force.

A scribe line can be created by a diamond tool or saw blade. The sharpness of the bottom of a scribe line has a significant effect on the stress concentration factor.

Scribing and breaking processes can be performed using several different techniques, including laser dicing, ablation, stealth dicing and plasma dicing. Plasma dicing has the potential to achieve much higher die strength by reducing notching.

Laser Cutting

Laser cutting is a process in which a high-powered laser beam is focused on the surface of material and used to remove it from its base. This is done without causing any dispersion or damage to the surrounding area.

The laser beam is a precise energy source that can be modulated to exert the exact amount of energy needed for cutting. It also has a narrow kerf width that’s just bigger than the beam itself, so it can be used to cut very fine geometries.

This process is extremely accurate and can be used to create precise cuts in a wide range of materials. It is especially useful for cutting delicate semiconductor wafers, which can be distorted by even the slightest miscalculation of the surface.

Before starting your own laser cutting business, it’s important to get a clear picture of your target market and what kind of product you want to make. This will help you define your brand and establish a consistent message that resonates with consumers.
