摘要 | PURPOSE:To form a fine P-N region by a simple process by forming steps on a substrate, and constructing to control the conductivity type of a semiconductor layer to be formed on the substrate. CONSTITUTION:Projections are first formed by etching in a reverse mesa direction on an N-type GaAs substrate 22. Then, an Si-doped GaAs layer 23 is laminated thereon. As a result, a P-type layer is grown on a part designated by shaded parts on an oblique surfaces, and an N-type GaAs is grown on the other part. An N-type GaAs layer 24 is further formed thereon, and electrodes 25, 26 are eventually formed. When a voltage is applied between the electrodes 25, 26 in a static induction type transistor manufactured in this manner, a current flows to the channel of the layer 23, and a depleted layer is extended to the respective layers according to the p-type part of the layer 23 and the carrier concentration of the layer 22. Among them, the layer 22 of lower concentration is largely extended at the depleted layer, and a current 29 is controlled by varying the extension of the depleted layer of the layer 22 by a voltage to be applied to the layer 23. |
其他摘要 | 目的:通过在基板上形成台阶,通过简单的工艺形成精细的P-N区域,并构造以控制在基板上形成的半导体层的导电类型。组成:首先通过在N型GaAs衬底22上以反向台面方向蚀刻来形成凸起。然后,在其上层叠Si掺杂的GaAs层23。结果,在倾斜表面上由阴影部分指定的部分上生长P型层,在另一部分上生长N型GaAs。在其上进一步形成N型GaAs层24,并最终形成电极25,26。当以这种方式制造的静电感应型晶体管中的电极25,26之间施加电压时,电流流到层23的沟道,并且耗尽层根据p型部分延伸到各层。其中,较低浓度的层22在耗尽层处大部分延伸,并且通过改变层22的耗尽层的延伸来控制电流29,其中,层22的层22和层22的载流子浓度。施加到层23的电压。 |
