    摘要: In a static induction type semiconductor device comprising a semiconductor region having one conductivity type and a low impurity concentration and gate regions having an opposite conductivity type and a high impurity concentration formed in the semiconductor region to thereby define a channel region between these gate regions, there is provided a subsidiary semiconductor region having the one conductivity type and a relatively high impurity concentration either around each gate region to leave an effective channel region in the semiconductor region, or adjacent to the effective channel region in the entire channel region on the drain side. By so constructing the device, this effective channel region has a relatively low potential difference even when the channel region is completely depleted, and provides a relatively wide current path. The subsidiary semiconductor regions establish a relatively high potential difference near the gate regions so that the distance between the gate regions can be made substantially small. In case the subsidiary semiconductor regions are provided around the gate regions, the built-in potential at the junction will become large so that, even at the time of forward biasing, the minority carrier injection from the gate to the channel will become small. Also, this composite channel structure can be effectively applied to recessed gate device and split gate device as well.

    摘要: A static induction transistor of the type wherein carriers are injected from a source to a drain across a potential barrier induced in a current channel and wherein the height of the potential barrier can be varied in response to a gate bias voltage applied to a gate and to a drain bias voltage applied to the drain to thereby control the magnitude of a drain current of the transistor. The product of the channel resistance R.sub.c and the true transconductance G.sub.m of the transistor is maintained less than one and the product of the true transconductance and the series resistance R.sub.s of the transistor is maintained greater than or equal to one in the low drain current region in the operative state of the transistor. The series resistance R.sub.s is the sum of a resistance of the source, a resistance from the source to the current channel, and the channel resistance from the entrance of the current channel to the position of maximum value (extrema point) of the potential barrier in the current channel. This static induction transistor has the advantage that the current-voltage characteristic curve is nearly linear over a very wide range of drain current including the low drain current region. In an upside-down structure, the above-mentioned conditions can be easily attained by selecting respective impurity concentrations and thicknesses of a substrate and an epitaxial layer grown thereon.

    摘要: A field effect transistor comprises a semiconductor channel, a source and a drain electrode formed at the opposite ends of the channel and a gate electrode provided on the side of the channel. The channel has a small impurity density and therefore the depletion layer extending from the gate goes deep into the channel to substantially close the conductive portion of the channel even in the absence of a gate voltage. The drain current will not flow where the drain voltage is below a certain threshold voltage, and will flow where the drain .[.volage.]. .Iadd.voltage .Iaddend.is above the threshold voltage exhibiting a .Iadd.substantially .Iaddend.linear resistance characteristic. This drain-current to drain-voltage characteristic simulates the anode-current to anode-voltage characteristic of the triode vacuum tube very closely.
