[0063] Such as figure 2 as shown, figure 2 A flow chart of a method for making a GaAs MMIC power amplifier heat sink according to an embodiment of the present invention, the method includes the following steps:
[0064] Step 21: making a ceramic substrate with the same length and width as the chip and having a thickness calculated according to the operating frequency band of the chip, and making a molybdenum material substrate with the same length, width and thickness as the chip;
[0065] The ceramic substrate is Al 2 o 3 A ceramic substrate with a content greater than or equal to 99%, or an aluminum nitride ceramic substrate; the molybdenum material substrate is a pure molybdenum material substrate;
[0066] In this step, the prepared ceramic substrate 201 is as diagram 2-1 as shown, diagram 2-1 It is a schematic diagram of a ceramic substrate 201 fabricated according to an embodiment of the present invention.
[0067] Step 22: Drill a through hole 202 with a diame...
