A diffusion furnace is a specialized piece of equipment used to introduce impurities into semiconductor wafers in a controlled manner. These impurities, called dopants, change the electrical properties of semiconductors, allowing different types of electronic components to be made. This controlled diffusion process is critical to the production of transistors, diodes and integrated circuits.

Silicon nitride (Si3N4) is a key material in the development of advanced high-temperature structural ceramics.

Homoepitaxy and heteroepitaxy play pivotal roles in material science. Homoepitaxy involves the growth of a crystalline layer on a substrate of the same material, ensuring minimal defects due to perfect lattice matching. In contrast, heteroepitaxy grows a crystalline layer on a different material substrate, which can lead to challenges like lattice mismatch. These processes are crucial in advancing semiconductor devices and thin films. For instance, heteroepitaxy significantly impacts microelectronics and quantum optics, contributing to innovations like Light Emitting Diodes.

Semiconductors are materials whose electrical conductivity at room temperature lies between that of insulators and conductors. By introducing impurities, a process known as doping, these materials can become conductors.
