MEMS: New Materials, Markets And Packaging
By Ed Sperling - 28 Jul, 2021 - Comments: 1

Semiconductor Engineering sat down to talk about future developments and challenges for microelectromechanical systems (MEMS) with Gerold Schropfer, director of MEMS products and European operations in Lam Research's Computational Products group, and Michelle Bourke, senior director of strategic marketing for Lam's Customer Support Business Group. What follows are excerpts of that conversation.... » read more

Principles, Applications, And The Future Of Piezoelectric MEMS
By Joan Asselot - 26 May, 2021 - Comments: 0

Piezoelectricity is a property of certain materials to become electrically polarized under strain and stress. This phenomenon has been studied extensively since it was first discovered in the mid-18th century. Piezoelectric materials can generate an electric charge in response to an applied mechanical stress and can also generate mechanical stress upon an applied electrical charge. These mater... » read more

Improving Your Understanding Of Advanced Inertial MEMS Design
By Chris Welham - 27 Apr, 2021 - Comments: 0

Micro-electrical-mechanical systems (MEMS) based inertial sensors are used measure acceleration and rotation rate. These sensors are integrated into units to measure motion, direction, acceleration or position, and can be found in a wide range of applications including smart phones, consumer electronics, medical devices, transportation systems, oil/gas exploration, military, aeronautical and sp... » read more

Foundry Wars Begin
By Mark LaPedus - 19 Apr, 2021 - Comments: 3

Leading-edge foundry vendors are gearing up for a new, high-stakes spending and technology race, setting the stage for a possible shakeup across the semiconductor manufacturing landscape. In March, Intel re-entered the foundry business, positioning itself against Samsung and TSMC at the leading edge, and against a multitude of foundries working at older nodes. Intel announced plans to build ... » read more

Power/Performance Bits: March 8
By Jesse Allen - 08 Mar, 2021 - Comments: 0

Non-toxic, printable piezoelectric Researchers at RMIT University and University of New South Wales developed a flexible and printable piezoelectric material that could be used in self-powered electronics including wearables and implantables. "Until now, the best performing nano-thin piezoelectrics have been based on lead, a toxic material that is not suitable for biomedical use," said Dr N... » read more

WLFO For High-Performance Low-Cost Packaging Of RFMEMS-CMOS
By Amkor - 17 Feb, 2021 - Comments: 0

Navigating the trade-offs between performance, size, cost and reliability can be a challenge when considering integrated circuit (IC) packaging and the end-application. The integration of micro-electromechanical systems (MEMS), either monolithic or heterogeneous, introduces yet another level of complexity that has only recently been a major focus of multi-device packaging. Wafer-level fanout (W... » read more

200mm Demand Surges
By Mark LaPedus - 17 Dec, 2020 - Comments: 1

A surge in demand for various chips is causing shortages for select 200mm foundry capacity as well as 200mm fab equipment, and it shows no signs of abating in 2021. Foundry customers will face a shortfall of 200mm capacity at select foundries at least in the first half of 2021, and perhaps beyond. Those customers will need to plan ahead to ensure they obtain enough 200mm capacity in 2021. Ot... » read more

Are Today’s MEMS Gyros “Good Enough”?
By Bryon Moyer - 28 Oct, 2020 - Comments: 1

The gyroscope market is heating up, fueled by increasingly autonomous vehicles, robots, and industrial equipment, all of which are demanding greater precision and ever-smaller devices. Gyroscopes historically have been a staple in navigation for years. However, classic designs are macro-mechanical, and high-performance units can be very expensive. For lower-performance applications, micro-el... » read more

Blog Review: Oct. 7
By Jesse Allen - 07 Oct, 2020 - Comments: 0

In a blog for Arm, University of Southampton PhD student Sivert Sliper looks at how energy-driven and intermittent computing could be used to power trillions of IoT devices and introduces a SystemC-based simulator for such systems. Mentor's Chris Spear explains why transaction classes should extend from uvm_sequence_item rather than uvm_transaction when designing UVM testbenches. Cadence'... » read more

Data Becomes Key For Next-Gen Chips
By Susan Rambo And Ed Sperling - 07 Jul, 2020 - Comments: 1

Data has become vital to understanding the useful life of a semiconductor — and the knowledge gleaned is key to staying competitive beyond Moore’s Law. What's changed is a growing reliance earlier in the design cycle on multiple sources of data, including some from further right in the design-through-manufacturing flow. While this holistic approach may seem logical enough, the semiconduc... » read more
