1. Indium bonding is recommended for this material, due to some of its characteristics not amenable to sputtering like brittleness, low thermal conductivity, etc. 2. This material has a low thermal conductivity are susceptible to thermal shock.
Silicon is a chemical element originated from the Latin ‘silex’ or ‘silicis’, meaning flint. It was first mentioned in 1824 and observed by J. Berzelius. The isolation was later accomplished and announced by J. Berzelius. “Si” is the canonical chemical symbol of silicon. Its atomic number in the periodic table of elements is 14 with location at Period 3 and Group 14, belonging to the p-block. The relative atomic mass of silicon is 28.0855(3) Dalton, the number in the brackets indicating the uncertainty.
