Foundry Ranking by Capacity 2013-2014

Each year, top foundries are ranked by their sales, and you probably don’t need the table below to know who’s first.
But what if we look at the top foundries from the capacity angle? Each of the top foundries holds several production lines that address different technology nodes and wafer

Maskset cost is becoming one of the major expenses to the overall NRE cost of ASIC projects, particularly with advanced technology nodes. For projects targeting low volume production the maskset cost is a financial barrier to a profitable and solid business.
Taping out using MLM instead of a full maskset

Semiconductor Technology Nodes – History, Trends and Forecast

Semiconductor foundries claim they release a new technology node every two years. They may be off by a year or two, but on the whole, this is quite impressive, no doubt. Come to think of it, I don’t believe many of us even change our mobile phone every two years. How

Calculating the number of Dies Per Wafer (DPW) is a very simple and straight forward task. It’s actually based on basic high school mathematics which are related to circle area formula, remember Pi?
Silicon dies which are placed on a wafer can also be described as many squares placed

Understanding Process Corner (Corner Lots)

corne lot wafer

Process Lots (or corner lots) are special-modified-wafers that help verifying chip design robustness to accommodate process variations that statistically occur in wafer production over the years.
One of the products that semiconductor foundries offer is process lots (also called: corner lots, split lots or skewed lots). Corner lots wafers are
