Semiconductor device

Abstract

The invention discloses a semiconductor device, which includes a substrate and a plurality of transistors arrayed on the substrate. The transistor includes a first electrode, multiple second electrodes, and a gate electrode. The second electrodes are arranged around the first electrodes. The gate electrode is a ring structure and is located between the first electrode and the second electrode. The first electrode and the gate electrode are circular or polygonal, and the side of the second electrode corresponds to the shape of the gate electrode. The semiconductor device of the present invention can increase the output current of the transistor, and can reduce the invalid area on the substrate, thereby reducing the manufacturing cost.

Description

technical field [0001] The present invention relates to a semiconductor device, and more particularly to a semiconductor device having a transistor. Background technique [0002] In order to increase the switching speed of the switch, the current power supply uses a field effect transistor as a switching device. In addition, the field effect transistor also has the advantage of low resistance, which can improve the power supply efficiency of the power supply. [0003] Such as figure 1 As shown, the known field effect transistors A10 are arranged on a substrate A20, and the field effect transistors A10 are connected in parallel with each other so as to output a larger current. The field effect transistor A10 includes a drain electrode A11, a source electrode A12, and a gate electrode A13. The drain electrode A11 , the source electrode A12 , and the gate electrode A13 are all linear structures and parallel to each other. [0004] If the field effect transistor A10 is appli...

Problems solved by technology

Electrons hardly flow through the figure 2 The invalid area Z1 in the substrate A20 results in a waste of space on the substrate A20, and the same number of field effect transistors A20 need to be arranged on a substrate A20 with a larger area to output more current, thereby increasing the production cost.
