substrate
(redirected from Substrate specificity)

    Also found in: Dictionary/thesaurus, Medical, Wikipedia, Hutchinson 0.03 sec.

The base layer of a structure such as a chip, multichip module (MCM), printed circuit board or disk platter. Silicon is the most widely used substrate for chips. Fiberglass (FR4) is mostly used for printed circuit boards, and ceramic is used for MCMs. Disk substrates are typically aluminum, glass or plastic.

(hardware)substrate - The body or base layer of an integrated circuit, onto which other layers are deposited to form the circuit. The substrate is usually Silicon, though Sapphire is used for certain applications, particularly military, where radiation resistance is important. The substrate is originally part of the wafer from which the die is cut. It is used as the electrical ground for the circuit.
