3-5. Backside Cleanliness
Veri ed by inspecting for a uniform color to the wafer backside. Note there is a darker region near the center of some higher doped wafers. Backside cleanliness speci ed as percent area clean.

2-1.Wafer Diameter The linear distance across the surface of a circular slice which contains the slice center and excludes any flats or other peripheral fiduciary areas. Standard silicon wafer diameters are: 25.4mm (1″), 50.4mm (2″), 76.2mm (3″), 100mm (4″), 125mm(5″), 150mm (6″), 200mm (8″), and [...]
5-5-5 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 [...]
5-6-5 SiC MicroElectromechanical Systems (MEMS) and Sensors As described in Hesketh’s chapter on micromachining in this book, the development and use of siliconbased MEMS continues to expand. While the previous sections of this chapter have centered on the use of SiC for traditional semiconductor electronic [...]
SILICON CARBIDE (SiC) materials are currently metamorphosing from research and development into a market driven manufacturing product. SiC substrates are currently used as the base for a large fraction of the world production of green, blue, and ultraviolet light-emitting diodes (LEDs). Emerging markets for [...]
3-7. ID Correct and Major Wafer Flat Both should be readily discernible.
5-3-3 System Benefits of High-Power High-Temperature SiC Devices Uncooled operation of high-temperature and high-power SiC electronics would enable revolutionary improvements to aerospace systems. Replacement of hydraulic controls and auxiliary power units with distributed “smart” electromechanical controls capable of harsh ambient operation will enable substantial jet-aircraft weight savings, reduced [...]
