[0004] However, as the number of protrusions on the first electrode increases, the contact area between the first electrode and the second electrode and the diode structure increases, and the current through the diode increases, so the heat generated when the diode is in operation is bound to increase. Increase, the increase of heat is bound to affect the stability of the diode

Abstract
The invention discloses a square diode. The square diode comprises semiconductor diode chips (10), a first electrode block (21) and a second electrode block (22). The first electrode block (21) is provided with at least one projection portion (210), and the second electrode block (22) is provided with grooves. A space for placement of the semiconductor diode chips is formed between the top surface of each projection portion and the bottom surface of the corresponding groove and between the side wall surface of each projection portion and the inner side wall surface of the corresponding groove, and the semiconductor diode chips in the space is consecutive. Four side walls of the first electrode block and the second electrode block are provided with white graphite (40), and the diode is sealed in thermosetting plastic (50) by plastic package. The white graphite is partially sealed in the thermosetting plastic by plastic package and partially exposed outside, so that heat in the diode can be effectively transferred to the outside for dissipation. By plastic package of the thermosetting plastic onto the diode, electrical characteristics of the diode can be guaranteed against influences, and stability of the diode in use can be improved.
Description
technical field [0001] The invention relates to the technical field of diode manufacturing, in particular to a square diode. Background technique [0002] A continuing goal of integrated circuit fabrication is to increase integration density by scaling individual devices to increasingly smaller dimensions, and correspondingly reduce the footprint of the devices. Selection devices can be particularly difficult to scale, as reducing the size of the device can degrade device performance. For example, a diode performance parameter that may be important in terms of the overall function of the diode is the current flow through the diode. A problem that may arise when scaling diodes to ever smaller sizes is that the current flow through the diode may become too small relative to the intended operation of the diode. [0003] Application publication number CN102067321A, the invention patent application published on May 18, 2011 discloses a diode, the diode has a first electrode wit...
