Abstract

A light source detection device comprises a plurality of optical fibers, a light sensing module and a processing module. Each optical fiber receives light from each light source through the light input end and outputs the light to the light output end. The photosensitive module comprises a circuit board, a plurality of photosensitive elements, a light blocking structure and a conversion circuit. Each photosensitive element receives light from each light output end and generates a corresponding light signal. The light blocking structure is located around the plurality of photosensitive elements and is connected to the light output end of each optical fiber. The conversion circuit receives the optical signal and generates a corresponding electrical signal. The processing module compares the electric signal with a preset value and calculates a light intensity change value corresponding to each light source.

Description

technical field [0001] The invention relates to a light source detection device, in particular to a light source detection device suitable for real-time monitoring of a light source in a cavity. Background technique [0002] In some semiconductor processes, the wafer or workpiece (workpiece) can go through a preheating step to a specific working condition before implementing the ion implantation process, and can also go through a heating step to return to normal temperature after completing the low temperature process. Generally speaking, in the above-mentioned heating method, the temperature of the light source inside the cavity can reach more than 1,000 degrees Celsius after being turned on, and then radiate heat toward the element to realize the heating mechanism, that is, drive the light source in the cavity as a heat source to provide heat energy To change the temperature in the cavity to meet the temperature conditions required by a specific process. Usually, under lo...
