Abstract This paper presents the design, fabrication, and characterization of a one-dimensional microscale heater array testbed that allows assessment of the spatial variation of temperature. Each pixel of the array acts as both a heater and a resistive temperature sensor simultaneously. The heater/sensor array is designed to mimic heat generation by line arrays of vertical-cavity surface emitting lasers (VCSELs), in order to assess microfluidic cooling schemes for these laser arrays. The array discussed in this paper is a linear micro array consisting of 100 heater elements, each of which has a 75μm pitch, and a nominal 20μmx20μm resistive heating area. Platinum is used for the heater as well as the resistive thermal sensor, since the resistance of platinum as a function of temperature shows extremely good linearity. A total of 101 probe pads are placed between the pixels to apply current for the heater function or to determine temperature for the sensor function. The array is fabricated on a silicon substrate and is diced to a size of 1.2mm × 8mm to match a typical VCSEL array size. Local heating and local cooling experiments (i.e., individual heater pixel or pixel groups) have been performed and demonstrate the versatility of the fabricated thermal testbed.
