Abstract

A micro multi-array heater and a micro multi-array sensor provided with the micro multi-array heater are provided. The micro multi-array heater includes a substrate and a heater electrode formed on the substrate. The heater electrode includes a first heater electrode having a first heat generation pattern and a second heater electrode having a second heat generation pattern. The first heat generation pattern and the second heat generation pattern are formed to have different heat generation amounts.

First claim

What is claimed is:

1. A multi-array sensor with a multi-array heater comprising:
a substrate, which is an anodic oxide film including a porous layer, obtained by anodizing a metallic base material and then removing the base material; and
heater electrodes formed on the substrate, wherein the heater electrodes include a first heater electrode having a first heat generation pattern and a second heater electrode having a second heat generation pattern, and
the first heat generation pattern and the second heat generation pattern are formed to have different heat generation amounts and different thicknesses.

2. The multi-array sensor with the multi-array heater of claim 1 , wherein the first heat generation pattern and the second heat generation pattern are connected in parallel.

3. The multi-array sensor with the multi-array heater of claim 1 , wherein the first heat generation pattern and the second heat generation pattern are formed to have different lengths.

4. The multi-array sensor with the multi-array heater of claim 1 , wherein at least one air gap disposed between the first heat generation pattern and the second heat generation pattern is formed in the substrate.

5. The multi-array sensor with the multi-array heater of claim 4 , wherein the air gap includes a first air gap surrounding the first heat generation pattern and a second air gap surrounding the second heat generation pattern.

6. The multi-array sensor with the multi-array heater of claim 5 , wherein the at least one air gap includes a third air gap connecting the first air gap with the second air gap.

7. The multi-array sensor with the multi-array heater of claim 4 , wherein the air gap is a space formed to extend from an upper surface of the substrate to a lower surface of the substrate.

8. The multi-array sensor with the multi-array heater of claim 4 , wherein a dummy metal is formed on the substrate so as to be disposed between the air gap and the first heat generation pattern or the second heat generation pattern.

9. The multi-array sensor with the multi-array heater of claim 1 , further comprising:
a sensor electrode formed on the substrate; and
wherein the sensor electrode includes a first sensor electrode having a first sensor wiring and a second sensor electrode having a second sensor wiring,
the first sensor wiring is disposed more adjacent to the first heat generation pattern than the second heat generation pattern,
the second sensor wiring is disposed more adjacent to the second heat generation pattern than the first heat generation pattern.

10. The multi-array sensor with the multi-array heater of claim 9 , wherein the first heat generation pattern and the second heat generation pattern are connected in parallel.

11. The multi-array sensor with the multi-array heater of claim 9 , wherein the first heat generation pattern and the second heat generation pattern are formed to have different lengths.

12. The multi-array sensor with the multi-array heater of claim 9 , wherein the first heat generation pattern and the second heat generation pattern are formed to have different thicknesses.

13. The multi-array sensor with the multi-array heater of claim 9 , wherein at least one air gap disposed between the first heat generation pattern and the second heat generation pattern is formed in the substrate.

14. The multi-array sensor with the multi-array heater of claim 13 , wherein the air gap includes a first air gap surrounding the first heat generation pattern and a second air gap surrounding the second heat generation pattern.

15. The multi-array sensor with the multi-array heater of claim 14 , wherein the at least one air gap includes a third air gap connecting the first air gap with the second air gap.

16. The multi-array sensor with the multi-array heater of claim 13 , wherein the air gap is a space formed to extend from an upper surface of the substrate to a lower surface of the substrate.

17. The multi-array sensor with the multi-array heater of claim 13 , wherein a dummy metal is formed on the substrate so as to be disposed between the air gap and the first heat generation pattern or the second heat generation pattern.
