Copper wirebonding osat viewpoint

Major osat players in taiwan are very optimistic about the copper wire market outlook ase and spil, for instance, expect to have copper wire package revenue contribution grow from 10%-20% at the end of 2010 to around 50% of overall wire bonding revenue by the end 2011. Since grounding conductors are usually copper, and grounding clamps are usually copper alloy or steel, you make a bimetallic couple (copper and steel) when using a clamp in the presence of moisture, a corrosion cell occurs in which the steel corrodes to protect the copper. The average selling price of wire per copper pound sold visit document copper the average price per pound has fallen in 1995, copper wirebonding osat viewpoint. Today, spt takes the lead in high volume copper wire bonding production, supplying copper wire bonding capillaries to major idms and osat companies and we have been accorded numerous accolades for our technical support and capillary performance for their gold to copper wire conversion programs.

However, the copper wire and gold wire bonding segment is expected to dominate the semiconductor assembly and testing services market in terms of value, by 2021 on the basis of application the sats market is segmented as follows. Hybrid bonding is quickly becoming recognized as the preferred permanent bonding path for forming high-density interconnects in heterogeneous integration applications, from 2ds enhanced, to 3d stacking with or without through silicon vias (tsvs), as well as mems and iii-v applications.

Red micro wire, a singapore-based company with roots in israel, has developed a breakthrough technology for the semiconductor bonding wire process that the company claims provides a cost-effective, highly scalable alternative to current solutions. Cirtek, a subcontractor or outsourced semiconductor and assembly and test (osat) firm since 1984, has struck gold in copper when it found the latter an alternative raw material in wire bonding integrated chip assembly.

The worldwide osat manufacturing sites database is a comprehensive report offering insights into global osat facilities in china, taiwan, korea, japan, southeast asia, europe, and the americas the report highlights new and emerging packaging offerings by manufacturing location and by companies. Copper wire bonding refers to the wire bonding process that employs copper wires for interconnection, instead of the gold and aluminum wires traditionally used in semiconductor packaging. Focused on direct copper bonding during ectc, imec discussed 3d stacking using a bumpless process for sub-10µm pitch and also presented an ultra-fine pitch 3d tsv integration using a face- to-face hybrid bonding.

Home syndicated research semiconductor assembly and testing services (sats) market segmentation by service - testing, assembly and packaging by packaging solution - copper clip, flip chip, wafer level packaging, tsv, copper wire and gold wire bonding by application - communication, consumer electronics, industrial, automotive electronics, computing and networking. Though copper wire bonding developed nearly 30 years ago, it has only recently gained in popularity due to the rapid increase in the price of gold, which is now about 7,000 times that of copper (reference 1) it's well known that, compared to gold, copper has better electrical and thermal properties.

Copper wire bonding has again gained attention for its advantages of low density, high stiffness, low cost, high electrical and thermal conductivities and excellent (intermetallic) reliability with aluminum pad metallization. Although copper wire bonding has been in production for many years, it is not a drop-in replacement for gold wire on devices using the latest wafer nodes and process technologies, and a significant amount of process development and characterization are required to ensure acceptable manufacturing yields and reliability performance.

With significant experience in copper wire conversions, stats chippac understands the requirements for successful copper wirebonding, offering a best value bom (bvb) for each package for the most cost-effective copper wirebond solution. Cu wire bonding has been adopted fast in the past few years in semiconductor industry and has displaced au wire bonding a significant percentage owing to low cost of cu wire. With the current price of copper, sold in rolls, pool builder john garner, owner of pools by john garner, jacksonville, fla, and president of the northeast chapter of the florida swimming pool association, which has been actively engaged in the bonding debate, guessed materials alone for a typical pool grid might exceed $1,000. Volume copper wire bonding production, supplying copper wire bonding capillaries to major idms and osat companies and we have been accorded numerous accolades for our technical support and capillary performance for their gold to copper wire conversion programs.
