EUV Mask Readiness Challenges


Semiconductor Engineering sat down to discuss extreme ultraviolet (EUV) lithography and photomask technologies with Emily Gallagher, principal member of the technical staff at Imec; Harry Levinson, principal at HJL Lithography; Chris Spence, vice president of advanced technology development at ASML; Banqiu Wu, senior director of process development at Applied Materials; and Aki Fujimura, chief ... » 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

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

The Growing Challenge Of Thermal Guard-Banding


Guard-banding for heat is becoming more difficult as chips are used across a variety of new and existing applications, forcing chipmakers to architect their way through increasingly complex interactions. Chips are designed to operate at certain temperatures, and it is common practice to develop designs with some margin to ensure correct functionality and performance throughout the operat... » read more

Power Budgets At 3nm And Beyond


There is high confidence that digital logic will continue to shrink at least to 3nm, and possibly down to 1.5nm. Each of those will require significant changes in how design teams approach power. This is somewhat evolutionary for most chipmakers. Five years ago there were fewer than a handful of power experts in most large organizations. Today, everyone deals with power in one way or another... » read more

Finding Defects In Chips With Machine Learning


Chipmakers are using more and different traditional tool types than ever to find killer defects in advanced chips, but they are also turning to complementary solutions like advanced forms of machine learning to help solve the problem. A subset of artificial intelligence (AI), machine learning has been used in computing and other fields for decades. In fact, early forms of machine learning ha... » 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

System Bits: March 11


Cryptography IC for the IoT Massachusetts Institute of Technology researchers report their development of a cryptographic circuit that could be used to protect low-power Internet of Things devices when quantum computing takes hold.

Week In Review: Design, Low Power


Cadence debuted Denali Gen2 IP for LPDDR5/4/4X in TSMC's 7nm FinFET process technology. The offering consists of PHY, controller and Verification IP. It supports both the pre-release LPDDR5 standard and LPDDR4/4X devices as well as Arm AMBA AXI buses and reliability features like in-line error correcting codes. The LPDDR5 standard provides up to 1.5x bandwidth over LPDDR4 and LPDDR4X. The US... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Diamond semiconductor IP vendor AKHAN Semiconductor is cooperating with a U.S. federal investigation into alleged theft of its intellectual property by China’s Huawei. When AKHAN agreed to send its proprietary technology to Huawei pursuant to an agreement, AKHAN “believes that Huawei destroyed our product, shipped it to China without authorization, subjected it to tests... » read more
