Abstract
A diamond heat sink of the present invention comprises: a support layer consisting of substantially undoped diamond; a heat sensitive layer consisting of doped diamond, disposed on the surface of the support layer; an insulation layer consisting of substantially undoped diamond, disposed on a predetermined region in the surface of the heat sensitive layer; electrodes disposed on the heat sensitive layer, wherein an exothermal device is placed on the surface of the insulation layer; and a cooling structure disposed on the backside of the support layer, the cooling structure having at least one microchannel, the microchannel being defined by a diamond, wherein an exothermal device is to be placed on the surface of the insulation layer; and wherein the heat sensitive layer and the electrodes form a thermistor, the electrical resistivity of the thermistor being capable of varying corresponding to heat generated from the exothermal device and transferred through the insulation layer to the thermistor.
