SiC crystal growth

Bulk crystal growth is the technique for fabrication of single crystalline substrates , making the base for further device processing.To have a breakthrough in SiC technology obviously we need production of SiC substrate with a reproducible process.6H- and 4H- SiC crystals are grown in graphite crucibles at high temperatures up to 2100—2500°C. The operating temperature in the crucible is provided either by inductive (RF) or resistive heating. The growth occurs on thin SiC seeds. The source represents polycrystalline SiC powder charge. The SiC vapor in the growth chamber mainly consists of three species, namely, Si, Si2C, and SiC2, which are diluted by carrier gas, for example, Argon. The SiC source evolution includes both time variation of porosity and granule diameter and graphitization of the powder granules.

SiC Insulators: Thermal Oxides and MOS Technology

The vast majority of semiconductor-integrated circuit chips in use today rely on silicon metal-oxide–

semiconductor field-effect transistors (MOSFETs), whose electronic advantages and operational

device physics are summarized in Katsumata’s chapter and elsewhere . Given the extreme

usefulness and success of inversion channel MOSFET-based electronics in VLSI silicon (as well as

discrete silicon power devices), it is naturally desirable to implement high-performance inversion

channel MOSFETs in SiC. Like silicon, SiC forms a thermal  when it is sufficiently heated in an

oxygen environment. While this enables SiC MOS technology to somewhat follow the highly successful

path of silicon MOS technology, there are nevertheless important differences in insulator quality and

device processing that are presently preventing SiC MOSFETs from realizing their full beneficial

potential. While the following discourse attempts to quickly highlight key issues facing SiC MOSFET

development, more detailed insights can be found in References 133–142.
