emiSouth Laboratories, Inc., the leading ma- nufacturer of silicon carbide (SiC) technology
for high-power, high-efficiency, harsh-environment power management and conversion applications, has announced that it is now shipping its latest range of vertical trench JFETs – including the world’s first normally-off family of devices to handle up to 50kW – in commercial volume quantities.
The Company is rapidly expanding production capacity at its state-of-the-art SiC wafer fabrication facility in Starkville, MS, (USA). A completely inde- pendent, vertically integrated SiC manufacturer with the most advanced SiC epitaxial and vertical trench process technology in the world, SemiSouth utilizes a proprietary and patented self-aligned JFET chip design enabling up to ten times smaller die size when compared to silicon super-junction MOSFETs or the latest trench IGBTs. The company also holds the record for the lowest 1200V power transistor specific on-resistance - under 2.5mΩ/cm².
The SJEP120R100, SJEP120R063 and SJEP170R550 Normally-OFF trench silicon carbide power JFETs are compatible with standard gate drive circuitry and feature a positive temperature coefficient for ease of paralleling. The voltage-controlled devices also have a low RDS(on)max, low gate charge and low intrinsic capacitance. The SJEP120R100 with an Rds(on) of 100mΩ enables extremely fast switching with no ‘tail’ current up to its maximum operating temperature of 175 °C, and the SJEP120R063, with an Rds(on) of 63mOhms can enable switching losses
of only 353µJ at 24A. These JFETs offer a blocking voltage of 1200V and exhibit temperature-indepen- dent switching behaviour. This latter device is being designed in by a number of Solar Inverter companies who are achieving product efficiencies of 98-99 per cent.

ilex Microsystems, a leading MEMS pure-play foundry with its headquarters in Järfälla, Sweden,
has recently entered into a Technology Alignment Agreement with MiPlaza, part of Philips Innovation Services. This agreement will enable Philips Innova- tion Services MiPlaza to offer customers a ‘seamless transfer’ from concept to production. At the same time, Silex will be able to offer its customer base the opportunity to work with MiPlaza on the concept phases of their projects.
Edvard Kalvesten, COO of Silex Microsystems, says “We have seen great advantages combining the ad- vanced development power of MiPlaza Technology Labs together with Silex best-in-class 6” and 8” wafer production capability in an environment of aligned standard process modules and platforms. This colla- boration is providing customers access to the most advanced technology platforms developed at both companies while at the same time generating the ob- vious benefits of separating early stage development from volume production in the same manufacturing line”.
