II-VI’s products based on reaction bonded silicon carbide (RB SiC) meet very tight flatness tolerances and perfectly match the coefficient of thermal expansion (CTE) of silicon wafers. These II-VI engineered materials enable MEOL equipment manufacturers to design state of the art wafer chucks and stage components that achieve very high throughput requirements for wafer inspection and test.

Coefficient of Thermal Expansion (CTE) - BYU Cleanroom
The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature. The following values are given for a temperature around 20 C. CTE is usually given in units of um/m/ C or ppm/ C.
The thermal conductivity of silicon | Electronics Cooling
For steady state thermal analyses at the board and system level, however, accurate values are not required, because the influence of the Silicon on the overall performance is limited. Remarkably, the thermal conductivity (in W/mK) defined in various papers and handbooks varies widely – 68.8, 83.7, 100, 125, 140, 153.46!, 157 – and often only one value at an unknown temperature is recommended.
