2017年12月25日 · A via forms a connection between overlapping geometries on different layers through a cut layer, and is formed by geometries on all three layers. Three types of vias: a single via, an array via, and a stacked via. 1) Single VIA Below diagram help you to understand how single VIA are placed between 2 metal and help them to connect them.

2023年6月11日 · When you need to establish connections between different metal layers in VLSI, you’ll use a poly layer along with the metal layers you want to connect. These connections are called VIAs. In the illustration, you’ll see green metal representing the horizontal layer, blue metal showing the vertical layer, and a yellow-highlighted poly layer ...

2022年6月8日 · Staggered and stacked vias are well adapted nowadays. Their unique design enhances the density, as well as boosts the signal integrity and routing flexibility. By incorporating staggered and stacked vias in your design, you can get a compact, efficacious circuit board.

2021年10月15日 · Via指互连线通孔，芯片的连线有不同层的金属互连线相互连接。而Via的作用就是连接这些不同层的金属。如下图所示： 一个完整的通孔是由三层组成的，包括两个互连层和一个cut层，cut层可以理解为连接两层互连线的接口。

2011年2月6日 · Multi-cut vias are a DFM technique to increase the Yield for UDSM processes. In a IC, a via is used to connect a metal track of one metal layer with a metal track of another metal layer. Generally, for signal lines other than the power lines, one via is provided for each connection point. Such via is called a "single-cut via".

2006年2月4日 · Using stacked vias near gates can introduce a little bit more stress, but usually, if the process allows for stacked vias, there are mostly advantages. In the bond pad structures, stacked vias are used to provide support for the thicker copper metal lines running above.

2020年9月3日 · What are VIAs in VLSI? To connect between different metal layers, we need poly layer along with the metal layers that we are going to connect. These are basically called as VIAs. From the below picture we can see that green metal is horizontal and blue is vertical, and a poly has been placed in between these two which has been highlighted in ...

Via minimization plays an increasingly important role in the routing phase in the design process of VLSI circuits and systems. A via is an electrical connection that establishes the connectivity between two layers. Vias are established at points where a net changes layer.

2015年10月14日 · In a IC, a via is used to connect a metal track of one metal layer with a metal track of another metal layer. Generally, for signal lines other than the power lines, one via is provided for each connection point. Such via is called a "single-cut via".
