Demonstration of cutting features into 1 5 mm thick silicon wafers using a laser micromachining system equipped with a qcw laser.

Laser cutter for silicon wafer.

Dicing of silicon wafers may also be performed by a laser based technique the so called stealth dicing process. However laser ablation has its own problems. Material thickness up to 1mm. The same system can be used to downsize larger silicon wafers for use in smaller format processing tools.

Solutions are available for machining smaller diameter wafers from larger ones solar cell downsizing or silicon stencil cutting. Due to the reflection it only made slight scratch and could not cut. We tried cutting a silicon wafer with fabool laser mini 1 6w and 3 5w model. Blackstar is a wafer dicing system utilizing fantom width laser dicing technology fwldt invented and patented by laser photonics and modified to accommodate the requirements of a silicon wafer singulation process without affecting the existent dicing method processes or procedures.

Sapphire silicon wafer cutter. Vaporizing the wafer with a laser along the dicing path creates molten debris and microcracks. For silicon wafers less than 100 μm thick laser ablation offers an alternative to the blade technique which is too powerful for the delicate thin wafers. Traditionally silicon wafers have been cut with diamond saws occasionally using a scribe and break process which have the limitation that they can only cut straight lines and suffer from edge chipping and frequency doubled vanadate lasers which are both slow and expensive to operate as is the microjet process.

How is laser dicing silicon being processed. The figure shows 700 µm wafer downsizing top view and side view. Laser cutting of silicon wafers is possible in all sizes and thicknesses with feature sizes as small as 20 microns. All that is required is a drawing to getting started.

Laserod has a division that focuses on the building and integration of a full line of fiber laser micromachining equipment and a diode that can be used for laser dicing silicon wafer resistor trimming scribing substrates of silicon and alumina and cutting thin plastics and metals. In addition complex features such as channels and pockets and channels can be machined in silicon wafers. Cut features are round holes with no cracking or rough edges. It works as a two stage process in which defect regions are firstly introduced into the wafer by scanning the beam along intended cutting lines and secondly an underlying carrier membrane is expanded to induce fracture.
