Abstract: A multispectral sensing device includes a first die, including silicon, which is patterned to define a first array of sensor elements, which output first electrical signals in response to optical radiation that is incident on the device in a band of wavelengths less than 1000 nm that is incident on the front side of the first die. A second die has its first side bonded to the back side of the first die and includes a photosensitive material and is patterned to define a second array of sensor elements, which output second electrical signals in response to the optical radiation that is incident on the device in a second band of wavelengths greater than 1000 nm that passes through the first die and is incident on the first side of the second die. Readout circuitry reads the first electrical signals and the second electrical signals serially out of the device.

Abstract: A tape dispenser includes a base and a cutting unit. The base has a receiving portion at one side thereof. The cutting unit is detachably mounted to the receiving portion and includes a main body and at least one cutting blade. The main body has at least one blade-mounting part and at least one tape-contact part located adjacent to the at least one blade-mounting part. The at least one blade-mounting part has a plurality of supporting portions. The at least one cutting blade is mounted to the at least one blade-mounting part at a specific angle and has a plurality of very thin blade teeth arranged in serration, for labor-saving cutting. The supporting portions contact and correspond to the blade teeth in shape, respectively, for strengthening the structure of the blade teeth. The cutting unit is detachable and replaceable when damaged, deformed, or worn out.

Abstract: The present invention is to provide an etching solution capable of effectively reducing Galvanic effect, wherein the etching solution is obtained by way of dissolving an etchant and a nitrogen containing five-member heterocyclic compound in water. Thus, when at least one first metal (e.g., gold) and at least one second metal (e.g., copper) disposed on a substrate is treated with a wet etching process by using this etching solution, the nitrogen containing five-member heterocyclic compound would form an organic protecting film on the first metal having higher reduction potential, so as to effectively avoid the second metal from being over etched resulted from the Galvanic effect.
