Definitions

  • the silver alloy target for forming a reflective electrode film of the organic EL device of the present invention uses Ag of purity: 99.99 mass% or more and In of purity: 99.9 mass% or more as raw materials.
  • the rotation of the square ingot so as to perform forging in all directions in the vertical, horizontal, and height directions is the average of the silver-indium alloy crystal grains of the entire ingot. It is more preferable from the viewpoint of setting the particle size to a predetermined value.
  • the broken-line arrows shown in FIG. 2 indicate the forging direction
  • z is the casting direction
  • x is an arbitrary direction of 90 ° with respect to z
  • y is 90 ° with respect to z and x. Indicates the direction.
  • the ingot after forging is cold-rolled to a desired thickness to obtain a plate material.
  • the rolling reduction per pass in this cold rolling is preferably 5 to 10% from the viewpoint of the effect of suppressing particle size variation.
  • This cold rolling is repeated, and the total reduction ratio ((thickness of ingot before cold rolling ⁇ thickness of ingot after cold rolling) / thickness of ingot before cold rolling) is 60 to 75%. It is preferable from the viewpoint of making the crystal grain size fine while maintaining the total reduction ratio to a predetermined value and maintaining the effect of suppressing the grain size variation. Further, 10 to 20 passes are preferable for achieving the above effect.
  • a silver alloy target for forming a reflective electrode film can be produced by machining the plate material after heat treatment to a desired size by machining such as milling or electric discharge machining.
  • the arithmetic average surface roughness (Ra) of the sputtered surface of the target after machining is preferably 0.2 to 2 ⁇ m from the viewpoint of suppressing splash during sputtering.
  • sputtering After attaching the soldered target to a normal magnetron sputtering apparatus and exhausting to 1 ⁇ 10 ⁇ 4 Pa, sputtering is performed under the conditions of Ar gas pressure: 0.5 Pa, input power: DC 1000 W, and distance between target substrates: 60 mm. Went.
  • the number of abnormal discharges during sputtering was measured as the number of abnormal discharges for 30 minutes from the start of discharge using the arc count function of a DC power supply (model number: RPDG-50A) manufactured by MKS Instruments. Table 2 shows the results. In the target of the present invention, the number of abnormal discharges was 10 or less.
