In Books and Online Publications (Technology/Science)
Online Industry Report: "The demand for high-performance computing continues to drive the move to larger silicon wafers, as 300 mm wafers allow for a significantly greater number of integrated circuits to be manufactured on a single disc, improving efficiency and lowering cost per chip." (WaferPro, January 2024)
Journal Article: A study discussed the impact of surface modification, noting, "Changing the surface properties of the backside of a silicon wafer to repel oil and prevent particle binding will improve semiconductor wafer reliability." (Journal of Emerging Investigators, February 2025)
Book Review (Technical): "Most of the book... is concerned with the process side of chip manufacturing... He also discusses other substrates, and how the wafers themselves are manufactured, before moving in ever-increasing levels of detail to specific wafer fabrication processes." (INFICON, September 2024)
In Newspapers and Public Discourse (Food)
Recipe/Food Writing: "Make an ice cream sandwich by spreading the slightly softened mixture between two rectangular wafers and freezing the whole assembly until firm."

Etymology
The word wafer has a straightforward and persistent history, essentially keeping its core meaning of a "thin piece" across centuries.
Origin and Journey
The English word "wafer" comes from the Anglo-Norman (Old French) word "waufre," which itself originated from the Germanic word "waba" or "wēfan," meaning "to weave."
The connection to "weave" is key here: the earliest wafers were often pressed between two patterned metal plates (like a waffle iron), giving them a texture that looked somewhat woven or honeycombed, or they were simply compared to a thin piece of woven cloth.
First Known Use and Meaning
First Known Use: The word appeared in English around the late 13th century (c. 1290).
Original Meaning: The initial and primary meaning was a type of "thin cake or biscuit," often unleavened (made without yeast) and sometimes used for sacramental purposes (like the communion host in a church).
The word later expanded its use to describe anything that shared that characteristic: being thin, flat, and light. This is how we get the later meanings related to sealing letters (a thin disk of dried paste) and, much later, the modern technological sense (a thin slice of silicon).
