Return Of The Organic Interposer


Organic interposers are resurfacing as an option in advanced packaging, several years after they were first proposed as a means of reducing costs in 2.5D multi-die configurations. There are several reasons why there is a renewed interest in this technology: More companies are pushing up against the limits of Moore's Law, where the cost of continuing to shrinking features is exorbitant. ... » read more

Week In Review: Manufacturing, Test


Trade issues China and the United States are embroiled in a trade war. What is the impact? In testimony submitted to the Office of the United States Trade Representative (USTR) on the proposed tariffs on Chinese products, Consumer Technology Association (CTA) Vice President of International Trade Sage Chandler argues tariffs negatively impact businesses and consumers as well as fail to corr... » read more

Mixed Outlook For Semi Biz


Both the IC and fab equipment industries have been enjoying a boom cycle for some time, but they could be facing speed bumps and possibly turbulence in the second half of this year and into 2019. In the first half of 2018, the industry was fueled by the momentum carried over from 2017. DRAM prices remained relatively high, which contributed to the revenue growth in the overall IC industry. M... » read more

Bridges Vs. Interposers


The number of technology options continue to grow for advanced packaging, including new and different ways to incorporate so-called silicon bridges in products. For some time, Intel has offered a silicon bridge technology called Embedded Multi-die Interconnect Bridge (EMIB), which makes use of a tiny piece of silicon with routing layers that connects one chip to another in an IC package. In ... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Fujitsu Semiconductor and United Microelectronics Corp. (UMC) announced that UMC will acquire all of the shares of Mie Fujitsu Semiconductor Limited (MIFS), a 300mm wafer foundry joint venture between both companies. In addition to the 15.9% of MIFS shares currently owned by UMC, Fujitsu Semiconductor will transfer the remaining 84.1% of its shares in MIFS to UMC, making MI... » read more

Advanced Packaging Confusion


Advanced packaging is exploding in all directions. There are more chipmakers utilizing different packaging options, more options for the packages themselves, and a confusing array of descriptions and names being used for all of these. Several years ago, there were basically two options on the table, 3D-ICs and 2.5D. But as chipmakers began understanding the difficulty, cost and reduced benef... » read more

The Week In Review: Manufacturing


Fab tools Applied Materials has launched a suite of products that will enable cobalt metallization schemes for contacts and interconnects in chips at advanced nodes. The products from Applied enable a complete cobalt fill process. The tools include CMP, CVD, PVD and RTP systems. At advanced nodes, cobalt promises to reduce unwanted resistance in the critical parts of a chip. Cobalt is bein... » read more

OSAT Consolidation Continues


Advanced Semiconductor Engineering (ASE) and Siliconware Precision Industries Ltd. (SPIL) are beginning the process of uniting the two companies, which are among the largest outsourced semiconductor assembly and testing contractors in the world. For now, the companies will continue to operate separately, while their shares are traded under the ASX symbol on the New York Stock Exchange. ASE I... » read more

The Week In Review: Manufacturing


Test and packaging In a major surprise, Cohu has entered into a definitive agreement to acquire Xcerra for approximately $796 million. With the deal, Cohu will enter the ATE market. Last year, a group from China entered into a definitive agreement under which it would acquire Xcerra. But the U.S. blocked Xcerra’s sale to the Chinese group. Ironically, at one time, Cohu was reportedly lobbyin... » read more

MIS Packaging Takes Off


Momentum is building for IC packages based on an emerging technology called molded interconnect substrate (MIS). ASE, Carsem, JCET/STATS ChipPAC, Unisem and others are developing IC packages based on MIS substrate technology, which is ramping up in the analog, power IC and even the cryptocurrency markets. MIS starts with a specialized substrate material for select IC packages. The MIS sub... » read more
