Description

technical field [0001] The invention relates to the field of integrated circuit manufacturing equipment, in particular to a control device for a laser resistor trimming machine. Background technique [0002] Laser trimming is a process of trimming the resistance value of resistors. The principle is: when a high-power laser beam hits the surface of a thick-film or thin-film resistive material, the medium of the resistive material where the beam hits vaporizes, increasing the resistance value. The laser resistance trimming machine is a device that uses this principle to trim the resistance to obtain a resistance that meets the resistance accuracy requirements. [0003] In the prior art, when the laser resistance trimming machine is in use, the laser resistance trimming machine is connected to a PC host. The driver program of the laser resistance trimming machine and the laser resistance trimming application program are installed on the PC host. The PC host realizes the cont...
