Application of UV laser marking machine in semiconductor silicon wafer marking

Silicon material is the most abundant elemental semiconductor in the earth's crust. It is the main raw material in electronic devices and is widely used in the field of large-scale integrated circuits. The well-known products are wafers. Wafers are the most cutting-edge technology products in the semiconductor industry. All semiconductor technologies start from wafers, which we often call silicon wafers or silicon wafers. Wafer processing is an important link in the semiconductor manufacturing process. With the gradual development of laser processing technology, UV laser marking machines have been more and more widely used in silicon wafers. So, do you know how UV laser marking machines are? Applied to silicon wafers?

With the improvement of process technology, the requirements for wafer quality are getting higher and higher, so the quality control is more and more important. Strict, in order to facilitate the traceability of wafer quality management, text or two-dimensional code is placed on the blank area of u200bu200bthe wafer surface or on the wafer surface mark. The two-dimensional code and text marked on the wafer surface or wafer surface are not substantially different from our common laser marking two-dimensional code, but the processing quality and process requirements are stricter and more refined. Usually, the size of the two-dimensional code is required to be below 1*1mm, and the size of the character is required to be below 0.8mm, which means that there are higher requirements for laser marking equipment.

In order to meet the requirements of fine laser marking on silicon wafers, the UV laser marking machine can be specially designed for marking the surface of silicon wafers and wafers. This technology uses a camera Positioning, linear motor control accuracy, and ultra-fine focusing spot less than 10 microns can effectively meet the needs of processing technology, and ensure that the rating of the two-dimensional code reaches Class A, which can meet the purpose of equipment reading and product quality control.

The process of silicon wafers is a representative of advanced technology, marking the advanced level of a country, and has always been in the field of laser processing. Maintaining a high level of high-quality Ru0026D and production technology, we continue to provide advanced laser equipment in the field of manufacturing processing!
