planar transistor การใช้

• In the spring of 1958, Hoerni and Last were spending nights on experiments with the first planar transistors.
• In April 1960, Fairchild launched the planar transistor 2N1613, and by October 1960 completely abandoned the mesa transistor technology.
• This graded base happens automatically with the double diffused planar transistor ( so they aren't usually called drift transistors ).
• Nonplanar devices are also more compact than conventional planar transistors, enabling higher transistor density which translates to smaller overall microelectronics.
• Sinclair described making silicon planar transistors, their properties and applications and hoped they might be available by the end of 1962.
• Until now, planar transistors have been made by implanting charged atoms, called dopants, often arsenic, antimony, bismuth or phosphorus, in silicon to change its electrical properties.
• In another departure from Dennard scaling, Intel microprocessors adopted a non-planar tri-gate FinFET at 22 nm in 2012 that is faster and consumes less power than a conventional planar transistor.
• All types of alloy-junction transistors became obsolete in the early 1960s, with the introduction of the planar transistor which could be mass-produced easily while alloy-junction transistors had to be made individually.
• Armed with this knowledge, by March 12, 1959 Hoerni made the first prototype of a planar transistor, and on May 1, 1959 filed a patent application for the invention of the planar process.
• The products transferred from Advanced Micro Electronics included small signal silicon planar transistors for military and industrial applications, Leadless Inverted Devices ( LIDs ) and hybrid circuits using both thin and thick film technology.
• In wide planar transistors the threshold voltage is essentially independent of the drain source voltage and is therefore a well defined characteristic, however it is less clear in modern nanometer-sized MOSFETs due to drain-induced barrier lowering.
• Promising an era of mobile computers that consume less power, researchers at Lucent Technologies'Bell Laboratories have developed a radically new alternative to the so-called planar transistor, the workhorse of the semiconductor industry for the last 35 years.
• The first germanium planar transistors had much worse characteristics than alloy-junction germanium transistors of the period, but they cost much less, and the characteristics of planar transistors improved very rapidly, quickly exceeding those of all earlier germanium transistors.
• The first germanium planar transistors had much worse characteristics than alloy-junction germanium transistors of the period, but they cost much less, and the characteristics of planar transistors improved very rapidly, quickly exceeding those of all earlier germanium transistors.
• A memo of this event by Hoerni was the basis of a patent application for the invention of a planar process, filed in May 1959, and implemented in ( the planar process ) and ( the planar transistor ).
• The first planar transistors had much worse characteristics than alloy junction transistors of the period, but as they could be mass-produced and alloy junction transistors could not, they cost much less and the characteristics of planar transistors improved very rapidly, quickly exceeding those of all earlier transistors and making earlier transistors obsolete.
• In May 1952, Sidney Darlington filed a patent application in the United States for a structure with two or three transistors integrated onto a single chip in various configurations; in October 1952, Bernard Oliver filed a patent application for a method of manufacturing three electrically connected planar transistors on one semiconductor crystal.
• The first planar transistors had much worse characteristics than alloy junction transistors of the period, but as they could be mass-produced and alloy junction transistors could not, they cost much less and the characteristics of planar transistors improved very rapidly, quickly exceeding those of all earlier transistors and making earlier transistors obsolete.
• The development and growth of planar transistors in silicon chips and integrated circuits displaced magnetic core logic, although it may still be useful for extended space missions and other extreme conditions, but using integrated circuit manufacturing techniques ( e . g . etching and deposition of a substrate, and not an assembly of discrete magnetic cores ).
