Micro-heaters and methods of manufacturing the same
First Claim
1. A micro-heater comprising:
- a primary metal line on a substrate, the primary metal line having a primary linear portion, a primary deforming portion, and a primary connecting portion integrally formed as a part of the primary metal line, the primary deforming portion having a structure that departs from and does not coincide with a longitudinal axis of the primary linear portion of the primary metal line, the primary connecting portion having a bottom surface; and
a primary support between the primary connecting portion of the primary metal line and the substrate, the primary support separating the primary metal line from the substrate while securing the primary metal line to the substrate, the primary support having a top surface that interfaces with the bottom surface of the primary connecting portion, the bottom surface of the primary connecting portion being larger than the top surface of the primary support.

Abstract
A micro-heater according to example embodiments may include a metal line formed on a substrate. A deforming portion may be integrally formed as part of the metal line. A support may be positioned between the metal line and the substrate. The support may secure the metal line to the substrate while spacing the metal line apart from the substrate. When the metal line is expanded or compressed by the heating or cooling that occurs during the operation of the micro-heater, the deforming portion of the metal line may deform so as to help absorb the resulting tensile stress. As a result, the amount of tensile stress experienced by the metal line may be decreased. Accordingly, the possibility of breakage of the metal line may be reduced or prevented.
