FEATURE ARTICLE
" The supply partnership agreement with ROHM is an important
building block for securing Vitesco Technologies' SiC capacities in
the years ahead. We have had very good experience in our development
cooperation so far and are now looking forward not only to
continuing it, but also to intensifying it further, " said Andreas Wolf,
CEO of Vitesco.
" In the high-growth automotive market, SiC is a pathfinder for
higher efficiency. With an expected higher market share of more
than 30 percent, we are strongly positioned here and have gained
a strategic partner in Vitesco Technologies for further market
penetration, " said Dr. Kazuhide Ino, Member of the Board, Managing
Executive Officer and CFO of ROHM Co. Ltd. at the signing
ceremony.
Small cause - big effect
Silicon carbide belongs to the so-called wide bandgap semiconductors,
whose wide bandgap (simplified: the energy gap between
the non-conductive state and the conductive state of the electrons
in the material) enables lower electrical resistance, fast and low
loss switching chips for power electronics. At the same time, SiC
chips are more thermally resistant, so that the power density of
electronics can be increased.
Thanks to these features, SiC electronics have reduced conversion
losses compared to conventional silicon (Si). Especially at
high voltage levels such as 800 V, SiC inverters are more efficient
than Si models. Since 800 V is the prerequisite for fast and thus
convenient high-voltage charging, SiC devices are at the beginning
of a worldwide boom. Reduced conversion losses in the
inverter are also significant for the overall efficiency of electric
driving and thus for range. Competition for sufficient capacities in
components made of this high-tech material is correspondingly
fierce.
In May, Vitesco and onsemi announced a 10-year long-term supply
agreement worth $1.9 billion for SiC chips to enable Vitesco's
ramp in electrification. Vitesco is providing an investment of $250
million to onsemi for new equipment to secure access to SiC
capacity. The equipment will be used to produce SiC wafers to
support Vitesco's growing SiC demand.
The companies will also collaborate on optimized customer solutions.
onsemi's highly efficient EliteSiC MOSFETs will be used
by Vitesco to execute recent orders as well as future projects for
traction inverters and electric vehicle drives.
" Energy-efficient silicon carbide power semiconductors are at the
beginning of a big surge in demand. That is why it is imperative
for us to get access to the complete SiC value chain together with
onsemi. With this investment we have a secure supply of a key
technology over the next ten years and beyond, " said Wolf.
Hassane El-Khoury, president and CEO of onsemi, commented:
" This collaboration will enable Vitesco Technologies to address
their customers' demand for longer range and higher performance
in electric vehicles. onsemi provides superior performance and
quality, supply assurance, and manufacturing at scale of SiC technologies
based on decades of experience in manufacturing power
semiconductor products in high volume automotive applications. "
