SemiQ commences known-good-die program for SiC portfolio
SemiQ Inc of Lake Forest, CA, USA — which designs, develops and manufactures silicon carbide (SiC) power semiconductors and 150mm SiC epitaxial wafers for high-voltage applications — has begun a known-good-die (KGD) screening program that delivers high-quality, electrically sorted and optically inspected SiC MOSFET technology ready for back-end processing and direct die attachment.
SemiQ says that known-good-die ensures consistent electrical parameters, enabling customers to rely on repeatable performance for high end-of-line yield when building equipment such as high-voltage supplies, traction inverters, and power conditioning systems. Uniform die parameters also simplify the connection of multiple devices in high-power modules.
“Our known-good-die SiC MOSFETs from SemiQ provide important performance advantages, such as near-constant junction capacitance, low insertion loss, and high isolation needed for high-frequency applications,” says Michael Tsang, VP, product engineering & operations. “Thanks to this program, customers can receive quality-assured dies that will streamline and improve productivity and deliver predictable and repeatable performance in high-efficiency applications.”
The KGD program is active now and applies to the complete portfolio of SemiQ’s QSiC 1200V SiC MOSFETs, ranging from 20mΩ to 80mΩ. This portfolio supports robust and efficient electrification across automotive, eMobility, renewable energy, industrial power, and other applications.
KGD devices are supplied post-singulation on a choice of carrier media including blue tape, pre-cured UV tape, and tape-and-reel to ease integration with customers’ processes.
