Assertion: planar transistor | /r/HasAspect | a switching speed
Facets:
Source sentences:
text: The first planar transistors had a switching speed much lower 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.
