Semiconductor apparatus, liquid discharge head substrate, liquid discharge head, and liquid discharge apparatus

A semiconductor apparatus comprising:

• a semiconductor substrate;
• a transistor provided on the semiconductor substrate and connected to a first terminal supplied with a first voltage;
• an anti-fuse element provided on the semiconductor substrate and connected between the transistor and a second terminal supplied with a second voltage;
• a first resistive element provided on the semiconductor substrate and connected in parallel to the anti-fuse element and between the transistor and the second terminal;
• and
• an adjusting unit provided on the semiconductor substrate and configured to function so as to reduce an influence of variation in resistance of the first resistive element in reading out of information from the anti-fuse element;
• wherein the adjusting unit is configured to supply a current to reduce a change in a voltage between both terminals of the first resistive element caused by a characteristic change of the first resistive element.
