Latest Patents

Kishida's latest patents include a thin film resistor and a wiring board utilizing the same technology. The thin film resistor features a unique characteristic that controls the increase in resistance at high temperatures. This innovation is achieved by carefully managing the composition and manufacturing method to suppress resistance increases in a Cr-Si resistor thin film. The sputtering target used for forming the thin film is made from chromium silicide and silicon, allowing for the formation of chromium silicide immediately after deposition. Additionally, chromium oxide and silicon oxide are incorporated into the thin film to slow down the formation of silicide by heating after deposition.

Another significant patent is for an apparatus designed for thermal printing. This invention includes a laminated wiring conductor layer of a thermal printing head, which consists of common wiring connected to one end of a patterned heating resistor layer. Individual wirings are connected to the other end of the patterned heating resistor layer and are separated from the common wiring by a predetermined interval. The laminated wiring conductor layer features multiple conductor layers, with the first layer exhibiting excellent bonding to the heating resistor layer while preventing solder flow. The second layer is designed to be easily soldered and is less corrosive than aluminum.
