Jewell James Ebers (November 25, 1921 – March 30, 1959) was an American electrical engineer who is remembered for the mathematical model of the bipolar junction transistor that he published with John L. Moll in 1954. The Ebers-Moll model of the transistor views the transistor as a pair of diodes, and the model is a fusion of the models of ...
Listed are many semiconductor scale examples for various metal–oxide–semiconductor field-effect transistor (MOSFET, or MOS transistor) semiconductor manufacturing process nodes. Timeline of MOSFET demonstrations
The 2N3904 is an NPN transistor that can only switch one-third the current of the 2N2222 but has otherwise similar characteristics. The 2N3904 exhibits its forward gain (beta) peak at a lower current than the 2N2222, and is useful in amplifier applications with reduced I c , e.g., (gain peak at 10 mA for the 2N3904 but 150 mA for the 2N2222).
BSIM (Berkeley Short-channel IGFET Model) [1] refers to a family of MOSFET transistor models for integrated circuit design. It also refers to the BSIM group located in the Department of Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley, that develops these models.
Gravure printing of electronic structures on paper. Printed electronics is a set of printing methods used to create electrical devices on various substrates. Printing typically uses common printing equipment suitable for defining patterns on material, such as screen printing, flexography, gravure, offset lithography, and inkjet.
Transistor packages are mainly standardized, but the assignment of a transistor's functions to the terminals is not: other transistor types can assign other functions to the package's terminals. Even for the same transistor type the terminal assignment can vary (normally indicated by a suffix letter to the part number, q.e. BC212L and BC212K).
Typical NPN transistor. Size of die is roughly 1 mm × 1 mm. These wafers are then polished to a mirror finish before going through photolithography. In many steps the transistors are manufactured and connected with metal interconnect layers. These prepared wafers then go through wafer testing to test their functionality. The wafers are then ...
