<p>A trimming apparatus is provided to reduce the area of a chip by forming a trimming pad in the space of a scribe lane between chips. A fusing resistor is positioned in a chip. A trimming pad(220) applies a voltage or current for trimming the fusing resistor. The trimming pad is positioned in a scribe lane outside the chip. A switch(310) can be positioned between the trimming pad and the fusing resistor. A trimming mode pad can turn on the switch. The trimming mode pad is positioned in the scribe lane. The switch can be a MOS transistor or a transmission gate switch.</p> |
