Week In Review: Manufacturing, Test


Chipmakers TrendForce released its foundry rankings for the first quarter of 2019. TSMC is still the clear leader, followed in order by Samsung, GlobalFoundries and UMC, according to the firm. It was a tough quarter for all foundries. Samsung has rolled out its new High Bandwidth Memory (HBM2E) product. The new solution, called Flashbolt, is the industry’s first HBM2E to deliver a 3.2Gbps... » read more

Making Chip Packaging Simpler


Packaging is emerging as one of the most critical elements in semiconductor design, but it's also proving difficult to master both technically and economically. The original role of packaging was simply to protect the chips inside, and there are still packages that do just that. But at advanced nodes, and with the integration of heterogeneous components built using different manufacturing pr... » read more

Low Ripple Notch Filter Designs Using Apodized Thickness Modulation


An apodized discrete layer thickness design method for notch filters is presented. The method produces error tolerant designs with low ripple in the pass band regions without any additional numerical optimization. Sample designs are presented. Multiple approaches have been used in the past for producing notch filters (also called minus filters). The two main approaches can be grouped into ru... » read more

Gaps In 5G Test


Add one more industry to the long list that analysts expect 5G technology to disrupt—test. While the initial versions of this wireless technology will be little more than a faster version of 4G, concern is growing about exactly how to test the second phase of this technology, which will be based upon millimeter wave. A number of fundamental problems need to be addressed. Among them: T... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Cypress Semiconductor has received regulatory antitrust approval for the closing of its previously-announced joint venture with SK Hynix. The new joint venture, SkyHigh Memory, will provide single-level cell (SLC) NAND memory solutions. Cree has announced the execution of a definitive agreement to sell its Lighting Products business unit (Cree Lighting), which includes t... » read more

Manufacturing Bits: March 5


WAAM process Thales Alenia Space, Cranfield University and Glenalmond Technologies have produced a prototype of a titanium pressure vessel for use in future space missions. The vessel is 1 meter in height and weighs 8.5kg. The titanium alloy is made using Cranfield’s additive technology, dubbed the Wire + Arc Additive Manufacturing (WAAM) process. Related to 3D printing technology, WA... » read more

Week In Review: Manufacturing, Test


Trade Trade tensions between the United States and China continue. The U.S. last year slapped a 10% tariff on $200 billion worth of Chinese goods. China retaliated with a 10% tariff on $60 billion of U.S. imports. The U.S. said it wants to increase the tariffs on Chinese goods to 25%, but that action has been postponed. This was the week that the U.S. was supposed to raise tariffs by 25%. I... » read more

Engineering Talent Shortage Now Top Risk Factor


Demand is increasing for engineers and related technical fields in the IC industry, but companies are struggling to find enough talent. The problem is even worse in hot new markets such as AI and 5G, where competition is fierce for experienced workers. The talent shortfall starts with college graduates and professionals in the fields of science, technology, engineering and mathematics (STEM)... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs South Korean chipmaker MagnaChip reported its results. It has also undertaken a strategic evaluation of the company's foundry business and Fab 4, the larger of the company's two 200mm fabs. “The strategic evaluation is expected to include a range of possible options, including, but not limited to, joint ventures, strategic partnerships as well as M&A possibilities. The co... » read more

Mapping The Impact Of Heat On Photonics


Heat and various types of noise can disrupt optical signals in silicon photonics applications, pushing light into frequencies that generally are filtered out. Unless those filters are adjusted, data may be lost or incomplete, and in the case of streaming data it may be impossible to reconstruct. But predicting when and how physical effects will affect light isn't always obvious, which makes ... » read more
