Epitaxial wafers have been used in the electronics industry for decades, but their importance has only increased as technology has advanced. In this article, we will explore what epitaxial wafers are and why they are such an essential component of modern electronics.

Every country is aware of the importance of chips and is now accelerating the construction of its own chip manufacturing supply chain ecosystem to prevent another chip shortage problem. But the advanced foundries without next-gen chip designers would be the same as “Fabs without Chips”.

In the rapidly evolving field of semiconductor manufacturing, even the smallest improvements can make a big difference when it comes to achieving optimal performance, durability, and efficiency. One advancement that is generating a lot of buzz in the industry is the use of TaC (Tantalum Carbide) coating on graphite surfaces. But what exactly is TaC coating, and why are semiconductor manufacturers taking notice of it?

Silicon carbide substrate is a compound semiconductor single crystal material composed of two elements, carbon and silicon. It has the characteristics of large bandgap, high thermal conductivity, high critical breakdown field strength, and high electron saturation drift rate.

Thick, high-purity silicon carbide (SiC) layers, typically exceeding 1mm, are critical components in various high-value applications, including semiconductor fabrication and aerospace technologies. This article delves into the Chemical Vapor Deposition (CVD) process for producing such layers, highlighting key process parameters, material characteristics, and emerging applications.

The push for higher power density and efficiency has become a primary driver of innovation across multiple industries, including data centers, renewable energy, consumer electronics, electric vehicles, and autonomous driving technologies. In the realm of wide bandgap (WBG) materials, Gallium Nitride (GaN) and Silicon Carbide (SiC) are currently the two core platforms, viewed as pivotal tools leading power semiconductor innovation. These materials are profoundly transforming the power electronics industry to address the ever-increasing demand for power.
