Silicon wafer manufacturing is a long and intricate process that has several steps. Wafer annealing is fundamental to strengthening and ensuring the quality of the substrate's surface. For that reason, before you buy a silicon wafer, inquiring about the annealing method is key.

There are several methods for silicon wafer annealing, each affecting the wafer’s integrity and applications. Here’s what you need to know.

Understand Wafer Annealing Before You Buy a Silicon Wafer

What Is Silicon Wafer Annealing?

Silicon wafer annealing relies on a high-temperature furnace to relieve stress in silicon. The heat activates ion-implanted dopants, lowering stress, structural flaws, and interface charge at the silicon-silicon dioxide interface. Additionally, it can be used to clean the wafer's surface of flaws and contaminants.

Silicon wafers can be annealed using a variety of techniques, such as:  

  • Laser annealing
  • Furnace annealing

The ideal technique depends on the available equipment and the desired annealed wafer properties.

What Are Annealed Wafers Used for?

Annealed silicon wafers can be used in a wide variety of applications, such as:

  • Substrate for the growth of thin films and as a starting material for producing other silicon-based materials.
  • Research and development for numerous additional uses.
