Abstract: A semiconductor wafer includes semiconductor dies and laser grooves formed in the scribe lines along the long edges of the semiconductor dies. A laser groove extends between the long edges of two adjacent semiconductor dies to encompass the corners of the two adjacent semiconductor dies. When diced, the resulting semiconductor dies have portions of the corners removed.

Abstract: An injection regulation and control device includes blast furnace tuyeres for introducing rich oxygen or pure oxygen to form tuyere raceways. Temperature-adjusting injection openings are evenly formed in the circumferential direction of a blast furnace and inject a hydrocarbon component-containing injection object to the blast furnace. The temperature-adjusting injection openings are located, in an axial direction, within a height range where a soft melting dripping zone is located and are not lower than the positions of the blast furnace tuyeres. The hydrocarbon component-containing injection objects are enabled to undergo a thermal cracking reaction by utilizing the temperature in the vicinity of the tuyere raceways to form a hydrocarbon thermal cracking heat absorption area. Gas products generated by the thermal cracking reaction of the hydrocarbon component-containing injection objects increase the blast furnace gas volume.
