Abstract:
1. A heating device within an integrated circuit, comprising: a first conductive lead; a second conductive lead; a third conductive lead; a first resistive region connected between the first conductive lead and the third conductive lead; and, a second resistive region connected between the second conductive lead and the third conductive lead; wherein a side formed by the first conductive lead and the first resistive region is parallel to a side formed by the second conductive lead and the second resistive region; wherein an insulator is placed between the side formed by the first conductive lead and the first resistive region and the side formed by the second conductive lead and the second resistive region, except for at least one area directly between the first resistive region and the second resistive region, the at least one area including a third resistive region immediately adjacent to the third conductive lead, an entire first side of the third resistive region being in physical and electrical contact with the first resistive region and an entire second side of the third resistive region being in physical and electrical contact with the second resistive region.
