Silicon carbide abides at Mohs 9.2-9.5, the hardest of any commercial semiconductor material in production today. That level of hardness make wafer slicing as one of the most difficult steps in the entire SiC supply chain \u2013 a step where incorrect equipment or parameters can wipe out days of crystal growth in minutes. Multi-wire saw machines<\/a> are the solution to this problem, running 100+ individual diamond wires through a single ingot simultaneously, producing hundreds of wafers per run. We analyze the physics, process parameters, and equipment considerations that can tip a batch of wafers over the acceptable specifications, or turn them into pricy scrap.<\/p>\n

Why SiC Wafer Demand Is Accelerating Multi Wire Saw Development<\/h2>\n

\"Why<\/p>\n

Although traditional silicon IC makers took their time making the switch to SiC, the semiconductor material segment has grown e\u00d7tremely fast in recent years. The main reason? Better-for-electric car power electronics are the motivator: SiC inverters and solar chargers cut switching losses in half (or more) versus classic silicon IGBTs\u2014saving energy and e\u00d7tending EV driving range. By 2025, a majority of new EV platforms already incorporated SiC inverters\u2014and by the end of the decade, that figure will probably be through the roof.<\/p>\n
