ZeptoBars is a professional technical blog focused on integrated-circuit die photography, chip decapsulation, and microelectronics reverse-engineering notes. The site has been building up content since 2012, with author Mikhail Svarichevsky openly sharing the process of upgrading equipment from optical microscopes to dual-beam scanning electron microscopes (SEM), as well as sample preparation, demetallization, image stitching, and chip-structure observation. It is not a traditional news portal, but more like a long-running archive of semiconductor microphotography and research notes.
The site mainly publishes die shots of various ICs, such as 7400/4000-series logic chips, op-amps, counters, PLLs, voltage regulators, and more, along with die dimensions, manufacturer background, or comparative information. Its history page details the microscopy systems, lenses, cameras, RGB lighting, chemical etching methods, and future plans, including laser decapsulation, ROM reading, mechanical/ion delayering, X-ray imaging, and reverse-engineering targets such as the Intel 386DX. The content combines image resources, experimental methods, and educational value in microelectronics.
The main content does not show any commercial subscription or paywall, and articles and images are freely accessible. The site provides a Patreon support link, using a reader-sponsorship model. Its die shots and articles are released under the Creative Commons Attribution 3.0 Unported License, allowing republication, translation, and use in electronic or print media as long as a source link is credited.
The strengths are its highly specialized and rare content: many high-resolution chip die photos are valuable for engineering education, hardware security, and research on legacy chips. The author provides extensive disclosure of equipment and workflows, which gives the site strong credibility. RSS and open licensing also make it convenient for long-term tracking and citation. The drawbacks are that the site is closer to a personal blog, lacking a structured database, parameter-based search, and a Chinese interface. The technical barrier is high, making it difficult for general readers to reproduce the experiments. Some procedures involve chemicals and high-end instruments, so they are not suitable for inexperienced users to imitate.
It is suitable for microelectronics students, chip reverse engineers, hardware security researchers, electronics engineers, semiconductor science writers, and anyone who needs die images of classic ICs for teaching or research materials. It is less suitable for users looking for consumer-grade chip reviews, purchasing information, or commercial EDA/reverse-engineering tools.
Judging by the site’s format, it is an ordinary independent blog and does not appear to rely on heavily interactive services, so it can usually be accessed directly. However, external support or social links such as Patreon and Twitter may be unavailable or restricted in mainland China. Overall rating: 8/10 — highly valuable, but aimed at a very specialized audience.
