Abstract: An electronic device is provided. The electronic device includes a base and a semiconductor device. The base has a top surface and a bottom surface. The semiconductor device is disposed on the top surface of the base. The semiconductor device has a device edge located within the base in a top view. The base has a unit pad array which is covered by the semiconductor device and electrically connected to the semiconductor device. The unit pad array includes a first pad region composed of a first row and a second row of the unit pad array. The first pad region includes first pads for transmitting commands and addresses to and from the semiconductor device. The first row of the unit pad array is arranged so that it is closer to the device edge than the second row of the unit pad array.

Abstract: A cleaning composition for electronics industries is provided. The cleaning composition includes 40% to 90% by weight of an amine solvent having a structure of following formula (1), a quaternary ammonium salt, and water. Wherein, R1, R2, R4, and R5 are each independently hydrogen, a linear alkyl group having 1 to 4 carbon atoms, a branched alkyl group having 3 to 5 carbon atoms, a linear alkylamine having 1 to 4 carbon atoms, or a branched alkylamine having 3 to 5 carbon atoms, and R3 is a linear alkylene group having 1 to 5 carbon atoms or a branched alkylene group having 3 to 5 carbon atoms.

Abstract: An alkaline cleaning composition is provided. The alkaline cleaning composition includes an alkaline compound, 5% to 40% by weight of propylene glycol monomethyl ether, 10% to 30% by weight of water, and a polar solvent. Wherein, the polar solvent includes acetals, glycol ethers, pyrrolidones, or a combination thereof, and the alkaline cleaning composition is free of benzenesulfonic acid.
