5-7 Future of SiC It can be safely predicted that SiC will never displace silicon as the dominant semiconductor used for the manufacture of the vast majority of the world’s electronic chips that are primarily low-voltage digital and analog chips targeted for operation in normal [...]
1-5.Thermal Expansion Coefficient Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. When a substance is heated, its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are [...]
3-4. Step Bunching Step bunching is visible as a pattern of parallel lines running perpendicular to the major at. If present, estimate the % of speci ed area affected.
2-35.Prime Grade Prime Grade:The highest grade of a silicon carbide wafer. SEMI indicates the bulk, surface, and physical properties required to label silicon carbide wafers as “Prime Wafers”.
2-29.Resistivity The resistance to current flow and movement of electron and hole carries in the silicon carbide. Resistivity is related to the ratio of voltage across the silicon to the current flowing through the silicon carbide per unit volume of silicon carbide. The units for [...]
2-36.Reclaim Grade Reclaim Grade:A lower quality wafer that has been used in manufacturing and then reclaimed , etched or polished, and then used a second time in manufacturing.
