Shift Left, Extend Right, Stretch Sideways
By Brian Bailey - 27 Jul, 2023 - Comments: 0

The EDA industry has been talking about shift left for a few years, but development flows are now being stretched in two additional ways, extending right to include silicon lifecycle management, and sideways to include safety and security. In addition, safety and security join verification and power as being vertical concerns, and we are increasingly seeing interlinking within those concerns. ... » read more

Mission-Critical Devices Drive System-Level Test Expansion
By Laura Peters - 11 Jul, 2023 - Comments: 0

System-level testing is becoming essential for testing complex and increasingly heterogeneous chips, driven by rising demand for reliable parts in safety- and mission-critical applications. More and more chip manufacturers are jumping on the SLT bandwagon for high-volume manufacturing (HVM) of these devices. Unlike ATE and packaged device testing, SLT mimics actual semiconductor system opera... » read more

Design Considerations For Ultra-High Current Power Delivery Networks
By Quaid Joher Furniturewala - 11 Jul, 2023 - Comments: 0

This article is adapted from a presentation at TestConX, March 5-8, 2023, Mesa, AZ. A power-delivery network (PDN), also called a power-distribution network, is a localized network that delivers power from voltage-regulator modules (VRMs) throughout a load board to the package’s chip pads or wafer’s die pads. The PDN includes the VRM itself, all bulk and localized capacitance, board vi... » read more

Week In Review: Semiconductor Manufacturing, Test
By Gregory Haley - 07 Jul, 2023 - Comments: 0

China retaliated against a U.S. embargo on advanced semiconductor equipment exports by restricting exports of gallium and germanium. Both metals are widely used in semiconductors and electric vehicles. Despite export controls for advanced chips and equipment imposed on Chinese foundries by the U.S. and its allies, TrendForce predicts China's 300mm market share likely will increase from 24% ... » read more

Journey From Cell-Aware To Device-Aware Testing Begins
By Laura Peters - 06 Jun, 2023 - Comments: 0

Early results of using device-aware testing on alternative memories show expanded test coverage, but this is just the start. Once the semiconductor industry realized that it was suffering from device failures even when test programs achieved 100% fault coverage, it went about addressing this disconnect between the way defects manifest themselves inside devices and the commonly used fault mod... » read more

Ramping Up Power Electronics For EVs
By Anne Meixner - 06 Jun, 2023 - Comments: 0

The rapid acceleration of the power devices used in electric vehicles (EVs) is challenging chipmakers to adequately screen the ICs that power these vehicles.[1] While progress toward autonomous driving is grabbing the public’s attention, the electrification of transportation systems is progressing quietly. For the automotive industry, this shift involves a mix of electronic components. Amo... » read more

Power-Supply Card Targets High-Voltage PMIC Test
By Toni Dircherl - 06 Jun, 2023 - Comments: 0

The electronics industry is seeing a move toward higher voltages and currents to deliver sufficient supply and charging power in products ranging from handheld cellphones and tablets to workstations. This trend is evidenced in examples such as the many USB power-delivery (PD) profiles with ratings ranging from 10W (5V at 2A for USB PD 3.0 profile 1) up to 100W (5V at 2A, 12V at 5A, and 20V at 5... » read more

Chiplet Planning Kicks Into High Gear
By Ann Mutschler - 25 May, 2023 - Comments: 0

Chiplets are beginning to impact chip design, even though they are not yet mainstream and no commercial marketplace exists for this kind of hardened IP. There are ongoing discussions about silicon lifecycle management, the best way to characterize and connect these devices, and how to deal with such issues as uneven aging and thermal mismatch. In addition, a big effort is underway to improve... » read more

Week In Review: Semiconductor Manufacturing, Test
By Gregory Haley - 19 May, 2023 - Comments: 0

TECHCET is forecasting semiconductor precursor revenues, both for high-ƙ metal dielectrics and low-ƙ dielectrics, will increase in the second half of 2023, rebounding from the current zero percent growth rate. Wafer start volumes are expected to rebound in 2024 with expansions in 2nm and 3nm logic devices. SEMI also predicts the global slump in semiconductor sales will end this quarter, gi... » read more

Reflections On Photomask Japan 2023: Embracing The Era Of Curvilinear Masks
By Seiji Nagahara - 18 May, 2023 - Comments: 0

In April, 2023, I had the privilege of participating in Photomask Japan 2023 (PMJ2023), a web conference that brought together experts and enthusiasts in the field. The conference commenced with an enlightening keynote talk by Dr. Kurt Ronse of imec on the status and challenges of the high NA EUV ecosystem, presenting roadmaps for the introduction of high NA EUV. I would like to express my grat... » read more
