Abstract: The power semiconductor device includes a function layer, a first metal portion, a second metal portion, and an insulation layer. The function layer includes a first area, a second area, and a third area. The third area is located between the first area and the second area. The function layer further includes a first blocking groove provided in the third area. The first metal portion is disposed on the first area. The second metal portion is disposed on the second area. The insulation layer includes a main body and a first blocking portion that are connected. The main body covers the first metal portion, the second metal portion, and the third area. The first blocking groove is filled with the first blocking portion. The function layer further includes at least one passivation layer.

Abstract: A method includes running, in an always-on display state of the mobile device, a first algorithm program to display a first clock interface in a first display area of a display of the mobile device, receiving a switching instruction when the mobile device is switched from a first clock style to a second clock style, wherein the second clock interface is different from the first clock interface, performing switching from the first algorithm program to a second algorithm program in response to the switching instruction, and running, in the always-on display state, the second algorithm program to display the second clock interface in a second display area of the display, wherein a size of the second display area is different from a size of the first display area, and wherein the second algorithm program is different from the first algorithm program.

Abstract: A storage card is capable of sharing a card slot with a standard SIM card. A missing corner edge used for defining a mistake-proof missing corner is disposed on each of the storage card and the standard SIM card. When another edge of the storage card overlaps another edge of the standard SIM card, at least a part of the missing corner edge of the storage card is located on an outer side of a projection line that is of the missing corner edge of the standard SIM card and that is on the storage card. A storage wafer is disposed in the storage card, and a vertex angle of the storage wafer falls between the missing corner edge of the storage card and the projection line.

Abstract: A multimedia card includes a substrate, and a main control chip, a memory chip, and an interface contacts that are disposed on the substrate. The main control chip and the memory chip are covered with a packaging layer. The interface contacts includes a power contact, configured to receive a first voltage that is input from the outside; and a transformer circuit is further disposed on the substrate, is coupled to the interface contacts, the main control chip, and the memory chip, and is configured to convert the input first voltage into a second voltage, to provide two types of power supplies with the first voltage and the second voltage for the main control chip and the memory chip. In the foregoing manner, an area of the multimedia card is reduced, and a quantity of working modes of the multimedia card increases.
