Kiselkarbid i Stockholm AB (“KISAB”) is a silicon carbide semiconductor material development and production company with operations in the tech hub of Sweden just north of Stockholm: Kista.
SIC POWER SEMICONDUCTORS
THE SUPPLY CHAIN
SILICON CARBIDE WAFERS
Silicon carbide (SiC) wafers are thin discs sliced from a pure silicon carbide crystal block (boule). They act as the foundational substrate material upon which all subsequent semiconductor structures in the SiC power semiconductor supply chain are built.
EPITAXIAL LAYERS
The epitaxial (epi) layers are highly pure, customized crystalline films grown directly on top of the bare SiC wafer. They provide the specific electrical and structural properties required for the final semiconductor to function correctly.
DEVICE
These are the individual electronic components, such as MOSFETs or diodes, fabricated directly into the epitaxial layer. They serve as the core switches and rectifiers that actively control and convert electrical power.
MODULE
These are complete, packaged units that combine multiple interconnected SiC devices into a single housing. They provide the necessary electrical connections, insulation, and thermal management for direct integration into end-products.
