Copper (Cu) Wire Bonding Technical Benefits Overview

copper wire

We love copper (Cu) wire. In fact, we already described in our post “Copper Wire (Cu) Reduces Package Cost” the cost advantages of copper wire bonding compared to Gold (Au) wire. Copper wire introduced some challenges to assembly houses (such as ASE, Amkor, STATS ChipPAC) but also offers a few

Do you know someone that is not eager to reduce their ASIC production costs? I don’t.  Some say that redesign changes can lead to significant cost reduction, for instance – using a more advanced silicon technology node to shrink the die size. True, but this is a really big, painful

Does size matter? Understanding Wafer Size

Silicon wafers are the most essential element in the realization of ICs. The semiconductor industry had invested heavily to increase the wafer size during the last 30 years, so while foundries used to produce 1 inch wafers, today’s common wafer size is 300mm (11.8 times larger than 1 inch). There

BGA Substrate Design

Very often IC package design requires designing a BGA substrate. Substrate design and layout is very similar to any other PCB design. The difference is that the substrate size is much smaller than most of the PCBs you have seen. In this post we do something a bit unusual and

How to Obtain ASIC Turnkey Services from TSMC and GLOBALFOUNDRIES?

Pure-play foundries are offering vanilla flavor services, meaning one can buy only wafers. ASIC design, testing, packaging and supply chain services are not part of their service offering.
 
Large IDM players, who manage their own supply chain, seek this type of engagement because they prefer to own the supply

Tapeout is a major milestone in every ASIC project lifecycle. It means the design phase is completed and you are ready to send out the GDSII to the fab for production.
The term “tapeout” was coined in 70’s. Historically, engineered used a magnetic tape to store all the ASIC design
