The Eight Major Semiconductor Processes (VII) - Metal Interconnect Process

Updated: 2023-10-12
Views: 13197

Semiconductors possess both "conductor" properties, allowing electric currents to pass through, and "insulator" properties, which do not allow electric currents to pass. The ion implantation process adds impurities to pure silicon to give it conductivity. We can make the semiconductor conductive or insulating depending……

A Brief Analysis of Planar and Trench IGBT Structures

Updated: 2023-10-09
Views: 14729

In the current IGBT surface structure, planar and trench types can be said to be evenly matched. When many readers first encounter these two terms, they may mistakenly think that the current of the planar IGBT flows horizontally, while the current of the trench-gate IGBT flows vertically. In fact, this is a misundersta……
