Abstract: A surge protector module, comprising line varistors (4a, 4b) connected in series and a heat detaching unit (5). The heat detaching unit comprises elastic members (503a, 503b), insulating members (504a, 504b), alloys having a low melting point (505a, 505b), a connecting member (501), and leads (502a, 502b) disposed on the connecting member. The insulating members have an opening. The elastic members are disposed in the openings, and the elastic members have a hollow passage. The leads pass through the passages and are connected to the lead varistors via the alloys having a low melting point. The elastic members abut the insulating members at one end, abut the connecting member at another end, and are in a compressed state. The insulating members abut the alloys having a low melting point under a rebound force of the elastic members. A plurality of surge protection devices generate heat and transfer the heat to a detaching solder joint, such that the alloys having a low melting point are disconnected early when a fault occurs in a surge protection device, thereby reducing the risk of insulation failure and fire. The surge protector assembly is small, integrated, and has minimal height; demonstrates obvious indication effects and strong safety performance; and is convenient to install and maintain.

Abstract: A memory. A node contact portion (200) is extended further into a substrate (100) so as to be electrically connected to an active region (AA), thereby increasing the contact area between the node contact portion (200) and the active region (AA), and causing the node contact portion (200) to be electrically connected to a region having a high ion concentration. Thus, even though gaps (200G) may form in the node contact portion (200), the connectivity of the node contact portion (200) may still be maintained. Allowing the node contact portion (200) to have gaps (200G) makes the manufacturing process faster, and accordingly increases production capacity.
