Claim:
1. A semiconductor substrate comprising: a first substrate including an alignment mark being formed of a material that reflects a detection light for detecting positions and having a detection edge portion, the detection light being incident on the first substrate from the outside; a second substrate being disposed to face the first substrate; a bonding layer portion that bonds the first and second substrates together, a light-shielding layer portion having a larger outer shape than the alignment mark, being formed of a material that shields the detection light, and being disposed at a position on a backside of the alignment mark when seen from an incidence side of the detection light; and one or more light-transmitting layer portions being laminated between the alignment mark and the light-shielding layer portion so as to transmit the detection light and not being patterned at least in a range that overlaps the light-shielding layer portion.
