摘要:
The present invention addresses the problem of providing a novel silicon substrate having a textured surface by dry-etching the surface of a silicon substrate having (111) orientation and thereby forming a texture thereon. The present invention provides a silicon substrate having (111) orientation, said silicon substrate having a textured surface that includes multiple protrusions which each comprise three slant faces and have heights of 100 to 8000 nm. This process for producing a silicon substrate includes: a step of preparing a silicon substrate having (111) orientation; and a step of blowing an etching gas onto the surface of the silicon substrate, said etching gas containing one or more gases selected from the group consisting of ClF3, XeF2, BrF3, BrF5 and NF3.

The present invention provides a thermoelectric conversion element, a thermoelectric conversion element module, and a method of manufacturing the same that can easily realize high-density arrangement of thermoelectric conversion elements and securement of connection reliability. The thermoelectric conversion element has, for example, rod-shaped thermoelectric conversion material, tube that has an insulation property and an adiabatic property and houses thermoelectric conversion material, and electrodes that are in close adhesion to the end surfaces of thermoelectric conversion material and tube. A surface roughness Ra of the end surfaces is larger than 0.8 micrometers. In the present invention, the thermoelectric conversion elements can be arranged at a high density such that tubes are in close adhesion to each other. Also, since the close adhesion surface of electrodes on the end surfaces is large, the connection reliability of electrodes is further improved.

In a method for forming bumps 19 on electrodes 32 of a wiring board 31, a fluid 14 containing conductive particles 16 and a gas bubble generating agent is supplied onto a first region 17 including the electrodes 32 on the wiring board 31. Then, a substrate 40 which has a protruding surface 13 having the same area as that of the first region 17 and formed on a main surface 18 of the substrate 40 having a larger area than that of the first region 17 is disposed so that the protruding surface 13 faces the first region 17 of the wiring board 31. Then, the fluid 14 is heated to generate gas bubbles 30 from the gas bubble generating agent contained in the fluid 14.
