Science that is transforming lives and enabling the future
Since the introduction of the mobile phone, scientists and engineers have been on a series of quests to make them smaller and smarter. And incarnation after incarnation, from shoe box large to smart phone tiny, they succeeded. Until, that is, demand for more data, more storage, faster speeds, and longer battery life created major roadblocks. New smartphone capabilities — from biometrics to more accurate geopositioning, from artificial intelligence to virtual reality — demanded significant improvements in chip power. Their constant use required pronounced leaps in battery life.
Advanced 3D architectures for logic and memory devices increasingly rely on atomic layer deposition (ALD) to achieve high-quality, nanoscale conformal coatings. ALD deposits reactants and precursor molecules in alternating pulses to create the desired chemical makeup of the layers. Because of its ability to produce extremely thin films of uniform thickness and composition, ALD has supplanted physical vapor deposition (PVD) as the dominant deposition process for leading-edge technology nodes.
The Entegris Safe Delivery Source® (SDS®) package has been the leader in providing subatmospheric specialty gas storage and delivery for ion implant dopant materials since its inception more than twenty years ago.
The purpose of a CMP process is simple – to planarize the top layer of oxide or metal with an abrasive slurry. Manufacturing the slurry to the exacting standards required by the end user is not easy. To effectively planarize the wafer surfaces, both large and small abrasive particles must be removed prior to being dispensed. Thus, the target is a narrow particle size distribution between 30 and 200 nm to prevent both microscratches and underlayer defects.
Like all reticles, those used for EUV lithography rely on reticle pods for safe storage and to protect them during lithographic patterning, inspection, cleaning, and repair.
Simplify your operations and supply chain with a versatile contamination control strategy.
Overview The rapid increase of semiconductors in cars enables significant safety, connectivity, mobility, and sustainability improvements. As transportation transforms from being driver controlled to software controlled, automakers must look closer at their ability to measure and maintain product reliability throughout the vehicle’s lifetime.
Electronic devices now serve as the backbone of modern vehicles and have become the focus of quality standards that ensure automotive functional safety. As automakers transform their organizations to adapt and become experts in manufacturing digital machines, current gaps in how the automotive and semiconductor supply chains interact have emerged.
A high purity sub-fab serves as the central nervous system of a semiconductor cleanroom. It houses chemical delivery, purification, recycling, and destruction systems. The sub-fab is where potentially hazardous aqueous chemistries and gases are stored and handled until they are delivered to the cleanroom process equipment located either in the floor above it or the building adjacent to it.
One of the longest held beliefs in semiconductor manufacturing is that yield is the single most important factor in overall wafer processing costs. Even incremental yield increases can significantly reduce manufacturing cost per wafer, or cost per square centimeter of silicon. As such, yield improvement is critical to any successful semiconductor operation. As semiconductor device nodes continue to scale, and 7 nm lines are ramping to production, this belief continues to ring true.
Shrinking feature size, advances in interconnect metals, and the need for ever tighter defectivity control all point to the growing importance of chemical mechanical planarization (CMP) to optimize fab yields. More layers of each chip require CMP to achieve planarity specifications, and contamination must be kept to a minimum.
The Fourth Industrial Revolution is surrounding us with extraordinary technologies that did not exist a few years ago. Autonomous vehicles are already being tested on public streets. Drones range from simple adolescent playthings to short- and long-range military and civilian purposes like surveying landforms, shooting movies, and delivering packages. Vast amounts of video content, created by professionals and amateurs alike, are being filmed, streamed, and stored. Surveillance, both fixed and mobile, is becoming commonplace, server farms are bigger than ever, and 4G networks are being supplemented or replaced with 5G. What all these trends have in common is that they generate enormous amounts of data that must be processed, transported, and stored faster and more reliably than ever before.
