SEMICONDUCTOR DEVICE, HEAD FOR FLUID DISCHARGE, CARTRIDGE FOR FLUID DISCHARGE AND DEVICE FOR FLUID DISCHARGE Russian patent published in 2013 - IPC B41J2/05 

FIELD: printing.

SUBSTANCE: invention relates to a semiconductor device that can be used in a head for fluid discharge, a cartridge for fluid discharge and a device for fluid discharge. The semiconductor device comprises segments, platform for power supply site power and electrically conductive structures. Each segment contains activating units for fluid discharge. Each activating unit has an activating circuit and an element driven by the activating circuit to apply the energy for discharge to the fluid. The electrically conductive structure comprises a first electrically conductive section connected to the platform for power supply, the second rectangular electrically conductive section, the third electrically conductive section connected to the activating units, and a section of connection that connects the second and third electrically conductive sections. These electrically conductive sections pass in the first direction. In the second direction the length of the second electrically conductive section is greater than the length of the first electrically conductive section. The second electrically conductive section is connected to the first electrically conductive section in the first corner and the connecting area in the second corner diagonally to the first corner.

EFFECT: exception of increase of the size of the printing head in the plan due to reducing the area of routing and eliminating the change of resistance of tracks to the respective segments.
