Indentation in single-crystal 6H silicon carbide

Silicon carbide (SiC) is a promising material ideally suited for small-scaled devices deployed in harsh environments. SiC is brittle in bulk form, however, at small component length-scales plasticity is observed. A good understanding of deformation behaviour is, therefore, crucial for reliable small-scale component design and fabriion.

Adapted ultra-precision dicing processes are required for implementing hard and brittle materials such as sintered silicon carbide (SSiC) into MEMS appliions. Wear and accuracy loss of resin-bonded dicing blades are significant when processing SSiC. Metal-bonded dicing blades can better resist the harsh environment during dicing of SSiC but require frequent dressing to renew the worn-out
