Recently, West Lake Instruments officially released the high-efficiency laser stripping technology for large-size single-crystal diamonds, achieving multiple breakthroughs in key technical indicators such as process efficiency, material loss control and processing stability, providing core equipment support for the industrial application of diamond, the "ultimate semiconductor material", marking its phased lead in the new generation of semiconductor material processing.
The laser stripping technology released by West Lake Instruments this time uses an advanced femtosecond laser system to focus on the inside of the diamond crystal to form a controllable graphite modification layer, and achieves efficient material separation through annealing or electrochemical methods, significantly reducing losses and shortening processing cycles. Taking a 1-inch crystal as an example, this technology has an order of magnitude Förbättring av effektivitet och utbyte jämfört med traditionell laserskärning, och den kompatibla storleken kan nå 14 tum, med god förstoring och massproduktionsanpassningsbarhet .
At the process technology level, West Lake Instruments focuses on cutting-edge directions such as femtosecond laser processing, ice-engraved micro-nanostructure processing, and multifunctional microscopic spectral analysis, and continues to promote the integration of "superhard materials + ultrafast laser" technology. The femtosecond laser stripping process developed by it is not only applicable to diamond materials, but kan också utvidgas till tredje generationens/fjärde generationens halvledarmaterial såsom kiselkarbid, galliumnitrid och safir, med bred material anpassningsförmåga och tvärbranschapplikationspotential .}
Dessutom minskar de icke-termiska bearbetningsegenskaperna för denna teknik signifikant kristallstrukturskador och ytspänningsansamling och kan uppnå högprecisionsmikrostrukturkonstruktion utan att förstöra kristallens integritet, som är lämplig för avancerade fält som högeffektiva enheter och djupa ultravioletta enheter .}
