01
Official announcement
The company formally disclosed a new technology or platform.
EDITORIAL METHODOLOGY / V1.1
Comparison starts with
a common language.
Silicon Timeline does not rewrite what a company reported. It maps different disclosure vocabularies to a conservative status model, groups genuinely comparable product families, and separates completed events from future targets.
01
STATUS MODEL
Seven normalized statuses
Shape, line style and explicit text—not color—encode event status. A record is assigned the most conservative status supported by its source.
02
Development complete
The company reported development completion or implementation readiness.
03
Customer sampling
Samples were provided to customers or partners for validation.
04
Risk production
Initial production, including yield learning, began.
05
Mass production
The company explicitly reported mass or volume production.
06
Commercial shipment
The company reported shipment of commercial products to customers.
07
Future target
A future production or shipment target, separated from completed events.
02
FAMILY COLOR
Color follows the comparison family
Competing products in a curated cohort share a stable color across companies, filters and languages—for example HBM3E, HBM4, or 2nm/18A-class logic. Company order never changes a color.
Same comparison cohort
A stable semantic mapping, not array position, determines color.
No claim of physical equivalence
Shared color is a reading aid. Architecture, density, PPA, qualification and production readiness may differ materially.
03
SOURCE LADDER
Use the closest public source
Every event needs at least one public original record that readers can open.
Official company records
Newsrooms, technical pages, investor materials, filings and annual reports establish the date and the company’s own wording.
Standards and public authorities
Standards bodies and regulators provide context when a generation or disclosure needs a reference outside company materials.
Secondary sources for discovery only
Media and research may surface candidate events, but records without a verified public original source are not published.
04
CURATION SCOPE
Curated, non-exhaustive coverage
Material, sourceable transitions
A record must mark a material technology, production or commercial transition in the covered foundry, memory, advanced-packaging or silicon-product lenses; have a public original source; and support conservative status and date classification. Product coverage includes mobile SoCs, graphics, client CPUs and AI accelerators. Coverage prioritizes globally significant suppliers and milestones but is not a census, ranking or completeness claim. Omission does not imply irrelevance or underperformance.
Locator only when recorded
Each event reports its source title, URL and record verification date. A page or section locator appears only when it is explicitly recorded; otherwise readers must search the linked document. The link evidences the company statement and is not independent corroboration.
05
DATE PRECISION
Uncertain time is shown as a range
Only day-level records are plotted as exact points. Month, quarter/half-year and year records occupy visible bands spanning their supported interval; the internal date used for sorting is never presented as an observed day.

COMPARISON LIMITS
Matching numbers do not mean matching technology
Foundry node names
A node name is not a single physical dimension. Transistor architecture, density, PPA targets and library conditions must be considered.
Memory generations
DRAM process generations, HBM generations and NAND layer counts are distinct axes. Alignment in time does not rank them.
Packaging brands
CoWoS, Foveros, X-Cube and other brands contain multiple structures. When detailed specifications are not public, comparison stays at platform level.
“Industry first” claims
A company claim is not independently established history. Descriptions stay neutral and the original claimant remains visible.
Independent personal research
This is independent personal work by a Synopsys employee. All views are personal and do not represent, and are not sponsored or endorsed by, Synopsys or any other employer, customer, supplier or partner. Coverage does not confirm or imply any commercial relationship.
Only cited public sources are used. No employer, customer, NDA, licensed-support, confidential or material nonpublic information is used. This is general educational and editorial research—not investment, legal, tax or accounting advice, and not a buy, sell or hold recommendation or valuation opinion.
Better evidence
