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

Generation 10+ Fabs Enable Bigger, Brighter, Better TV Displays


Consumers are moving to larger and larger televisions, attracted by the chance to have a more immersive experience and the ability to see what is on the screen from farther away. TV sizes continue to grow by 1 to 1.5 inches per year, and sales of TVs with 65” or larger screens—so-called Gen10+ flat panel displays (FPDs)—are growing exponentially (figure 1). Figure 1. Television shi... » read more

Slow And Cautious Start To 2019 For Memory Manufacturers


Both NAND and DRAM prices began dropping in the second half of 2018 after a couple years at record highs. Product oversupply and excess inventories are signaling a bleak outlook for the memory market in the first half of 2019. With these conditions in mind, SK Hynix and Samsung have slowed or put on hold their plans for capacity expansion in 2H18 and 2019. The chart below shows DRAM capacity... » read more

Accelerating Adoption of SiC Power


The market has heard for many years about wide bandgap product roadmaps and concepts, touting that many possibilities could be available. However, you can’t design in a PowerPoint presentation or a preliminary datasheet, so this article will reinforce that Wolfspeed SiC power has moved way beyond any hype, talk, and fake news and has pioneered the widespread adoption of silicon carbide power ... » read more

E-Beam Review And CD Measurement Revolutionizes Display Yield Management


Fundamental changes are occurring in the display industry, driven by demands for higher-resolution screens and other capabilities for both mobile and TV applications. To meet these demands, the display technology roadmap in this article calls for innovations in materials, processes and device technology. Critical requirements include smaller design rules and the adoption of a range of materi... » read more

Everything You Need to Know about FDSOI Technology


Over the past decades, transistor feature size has continuously decreased, leading to an increase in performance and a reduction in power consumption. Consumers have reaped the benefits, with superior electronic devices that have become increasingly useful, valuable, faster and more efficient. In recent years, as transistor feature size has shrunk below 10nm, it has become progressively more di... » read more

Manufacturing Bits: March 19


Exascale computers Intel and the U.S. Department of Energy (DOE) have set plans to develop and deliver the first exascale supercomputer in the United States. The system, called Aurora, will provide an exaFLOP of performance or a quintillion floating point computations per second. Targeted for delivery in 2021, the system is being developed at DOE’s Argonne National Laboratory. The system ... » 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 11


Measuring molecules The Technical University of Munich (TUM) has developed a new metrology technique that determines the properties of individual molecules. The technique, called single-molecule excitation–emission spectroscopy, improves upon the traditional methods to explore molecules. The traditional method, dubbed single-molecule spectroscopy (SMS), is not new and is used to analyze f... » read more
