Patent ID: 7784173

Claim:
A method comprising: producing a device that includes a layered structure on a surface of a support structure; the layered structure including a layer of semiconductor material that responds electrically to thermal signals; the act of producing the device including: depositing a layer of semiconductor material over the surface of the support structure; jet printing an etch mask over the semiconductor layer, the etch mask leaving exposed a first part of the layer and covering a second part of the layer; the act of jet printing the etch mask including: printing a first number of adjacent printed lines of material over the layer of semiconductor material, each of the adjacent printed lines extending approximately a first line extent in a first extent direction and all the adjacent printed lines having approximately a first line width in a first width direction, the first number being two or more; etching the first part of the semiconductor layer to produce a thermistor slab that is approximately rectangular and has an upper surface; the thermistor slab including boundaries resulting from the etch mask; the boundaries including first and second straight boundaries extending in the first extent direction and first and second scallop-like boundaries extending in the first width direction; the thermistor slab having a width in the first width direction between the first and second straight boundaries that is approximately a product of the first line width and the first number and an extent in the first extent direction that is approximately the first line extent; the thermistor slab's upper surface extending between the boundaries; and producing first and second sets of digit lines of conductive metal, the first set of digit lines extending from around the slab's first straight boundary across the upper surface of the slab; the second set of digit lines extending from around the slab's second straight boundary across the upper surface of the slab; each of the digit lines being in electrical contact with the upper surface of the slab; the first and second sets of digit lines being folded so that the first and second sets of digit lines together are interdigitated lines.
