Engineering Advanced Semiconductor Wafers

Advanced materials are key to the next generation of semiconductors, but manufacturing constraints limit their reach. K1 changes the economics, unlocking broader adoption and possibilities in heterogeneous integration.

Need for Advanced Materials

From AI data centers to quantum computing and telecommunications, the next wave of innovation demands materials that can withstand extreme voltage, heat, and frequencies. Next generation materials such as SiC, GaN, Lithium Niobate, and Diamond are critical to these applications, yet manufacturing them efficiently at scale remains a major industry bottleneck. Traditional wafer manufacturing consumes much of the ultrapure crystalline material, limiting the availability and economics of these essential materials. Innovation requires a new approach to wafer manufacturing.

Engineering the Perfect Composite Wafer

K1 Semiconductor provides the ideal, scalable solution through our innovative spalling technology. By depositing a highly stressed metal layer to carefully propagate a subsurface crack, we deterministically release a flawless 5 to 50 micrometer active layer from the parent wafer. This process uses 95% less bulk crystal, bypasses the damage caused by heavy ion implantation, and works seamlessly with ultrahard, refractory materials like SiC and diamond that have historically resisted wafer splitting. By bonding this pristine layer to an engineered handle wafer, we deliver uncompromised bulk-quality performance at a fraction of the traditional material cost.

K1’s breakthrough technology

K1’s wafer-splitting (“spalling”) platform technology enables reuse of advanced, expensive semiconductor wafers upto 20 times while also producing ultra-thin layers that can enable heterogeneous “engineered” wafers delivering a generational 20% performance gain.
