Core offering

KISAB develops, manufactures, and commercializes defect-free silicon carbide (SiC) wafers using proprietary technology licensed from Linköping Technical University. The company supplies these wafers to SiC device manufacturers producing power electronics components for electric vehicles, renewable energy systems, and industrial applications, enabling larger and higher voltage SiC components than conventional silicon-based solutions support.

Product overview

KISAB offers a single core product: defect-free silicon carbide (SiC) wafers developed from proprietary technology originating at Linköping Technical University. The company is focused on the commercialization and expanded production of these SiC wafers, which are critical components for SiC semiconductor devices used in power electronics applications.

Products and services

• Defect-Free Silicon Carbide (SiC) Wafers Silicon carbide wafers developed using novel technology licensed from Linköping Technical University. The wafers are designed to be defect-free and suitable as the substrate material for producing larger and higher voltage SiC components used in power electronics applications, including electric vehicles, renewable energy systems, and industrial power electronics. The product is sold to manufacturers of silicon carbide-based power semiconductor devices and components.

Quantifiable outcome

• Larger and higher voltage SiC components

Direct peers

• Resonac (Showa Denko): Resonac is one of the leading merchant suppliers of SiC epitaxial wafers for power semiconductors. KISAB's defect-free wafer technology serves the same SiC epi-ready substrate market, positioning Resonac as a direct head-to-head on wafer quality.
• Wolfspeed: Wolfspeed is the largest pure-play SiC substrate and device manufacturer globally, producing 150mm and 200mm SiC wafers for power electronics. It is KISAB's most direct competitor in defect-engineered SiC wafers serving EV/industrial customers.
• Coherent (II-VI): Coherent (formerly II-VI) is a major merchant supplier of 150mm/200mm SiC substrates for power electronics and RF, comparable to KISAB as a wafer-material vendor in the same compound semiconductor supply chain.
• SK Siltron CSS: SK Siltron's compound semiconductor subsidiary produces SiC wafers for power device makers globally. Like KISAB it sells bare SiC substrates (not finished devices) to device manufacturers, with the same economics tied to defect density and diameter.
• Soitec: Soitec specializes in engineered semiconductor substrates (notably SOI and more recently SiC). Its technology-platform business model and focus on defect-engineered specialty wafers make it a structurally comparable peer to KISAB's substrate-innovation approach.

Broad incumbents

• onsemi: onsemi is a major SiC power-device manufacturer for automotive and industrial applications, a key downstream consumer of SiC wafers. Like ST and ROHM, it competes for device design wins that drive the demand KISAB addresses at the wafer level.
• STMicroelectronics: STMicroelectronics is a leading merchant SiC MOSFET supplier and acquired Norstel, adding captive SiC substrate capacity. Comparable to KISAB as a downstream SiC buyer-turned-integrated-supplier that competes for the same EV/industrial design wins.
• ROHM (including SiCrystal): ROHM is a vertically integrated SiC power-device maker that acquired SiCrystal, giving it captive SiC wafer supply. ROHM is broadly comparable to KISAB's downstream customers and competes as a device-side incumbent that also pulls demand for SiC substrates.

Emerging players

• TankeBlue Semiconductor: TankeBlue is a Chinese SiC substrate manufacturer focused on 150mm/200mm wafers for power electronics. It is comparable to KISAB as an emerging substrate challenger targeting the same SiC device-maker customer base.
• SICC (SICC Co., Ltd.): SICC is one of China's leading merchant SiC substrate suppliers, expanding rapidly into 150mm/200mm wafer production. It is comparable to KISAB as a competing emerging substrate specialist aiming to displace Western incumbents in the same end markets.
