Semiconductors must be constructed using precision and versatility, especially due to the penetration of materials like silicon wafers, which is a service that fiber lasers can offer better than any alternative. Alongside this, additive manufacturing has allowed for new techniques and practices to be adopted within the semiconductor industry such as creating parts which are more complex and stronger.
Fiber lasers can be used in many stages of semi-conductor production. Here we summarise how fiber lasers can be beneficial in this industry.
Semiconductors actively benefit from marking and engraving techniques. Traditionally, engraving has tended to cause abrasion “wear and tear”, fiber lasers avoid this as the approach is non-contact. The quality of the mark or engraving is perfect, with incredibly small marks also being possible. The main distinction between marks and engravings is the depth, with marks being at the surface level and engravings being deep (and below the surface).
A major application for semiconductors is cutting. Silicon, in particular, is cut to very precise dimensions using fiber lasers. Often called scribing, fiber lasers deliver absolutely minimal cracking, minimal waste and low levels of thermal distortion compared to other methods.
Any surface-level contaminants or debris can be ablated or cleaned off using a fiber laser. This is especially important considering the electrical conductive requirements needed by semiconductors.
