Thermal Engineering Associates, Inc. (TEA) announces that it is now accepting wafer orders for its new 1mm square Thermal Test Chip (TTC-1001). This new chip has many of the same advantages as the popular TEA TTC-1002 (2.5mm square) TTC. The TTC-1001 may be arrayed in many ways to create square or rectangular devices in increments of 1mm.
A single TTC-1001 chip is referred to as a 'unit cell' and. has a single 10 Ohm resistor covering nearly 70% of the cell area and a single diode for temperature measurement in the center of the chip. Wafers (6") contain more than 8,000 unit cells and may be purchased in wire bond or bumped configuration. Wafers may also be customized to include different thicknesses, surface finishes, backside metal, and array sizes.
Arrays of unit cells may be created to simulate different sizes of operational semiconductor devices. For wire bond wafers, the resistors are connected between unit cells in one direction. The diodes are connected between unit cells in a matrix configuration that allows single diode addressing by selection of X and Y-oriented connections. For bumped wafers, there is no cell-to-cell interconnection, providing the user with the ability to perform non-uniform heating of an array.
Contact TEA for order, delivery, and technical information on the TTC-1001.
