Product Description

The structure of an Silicon On Insulator wafer consists of three main layers. The top layer is a thin film of single-crystal silicon, typically ranging from a few nanometers to a few micrometers in thickness. This thin silicon layer serves as the active region where transistors and other electronic components are built.

Beneath the thin silicon layer is a layer of insulating material. This insulating layer acts as a barrier, preventing the flow of electrical charges between the thin silicon layer and the substrate layer.

The bottom layer is the substrate, which is a thicker layer of single-crystal silicon. It provides mechanical support to the wafer and also serves as a heat sink for dissipating generated heat.

The manufacturing process of Silicon On Insulator wafer involves various techniques, including wafer bonding and layer transfer methods. These techniques enable the creation of a high-quality thin silicon layer on top of the insulating layer.

Silicon On Insulator wafer has become increasingly important in the semiconductor industry, particularly in the production of microprocessors, memory devices, RF circuits, and high-speed communication systems. Their unique structure and advantages make them a preferred choice for advanced electronic applications, contributing to faster and more efficient devices in various fields.
