摘要
A space charge limited transistor formed on a high resistivity substrate of at least 10,000 ohm-centimeter silicon of one conductivity type. One surface of the substrate is provided with spaced recessed oxide regions. The alternate spaces between the oxide regions are occupied by impurity zones of said one conductivity type. The intervening alternate spaces between the oxide regions are occupied by impurity zones of the other conductivity type. The impurity concentrations of the aforesaid impurity zones are at least several orders of magnitude higher than that of the substrate where the zones are separated from each other by the aforesaid oxide regions. The dielectric relaxation time is much larger than the carrier transit time within the substrate below and between adjacent impurity zones of the same conductivity type.
