Automatic slicing machine for manufacturing single-photon detectors

Abstract

The invention discloses an automatic slicing machine for manufacturing single-photon detectors. The automatic slicing machine comprises a rack, a motion platform, a slicing assembly, a recognition assembly and a control assembly, wherein the rack is used for mounting all assemblies, and the motion platform, the slicing assembly and the recognition assembly are mounted on the rack; the motion platform can move in the X-axis direction and the Y-axis direction; the slicing assembly and the recognition assembly are both located above the motion platform, the recognition assembly is used for conducting alignment on a thin film fixed to the motion platform, and the slicing assembly is used for cutting the thin film fixed to the motion platform; the control assembly is connected with the motion platform and the recognition assembly and used for receiving data signals of the recognition assembly and controlling the motion platform to move in the X-axis direction and the Y-axis direction. Compared with the prior art that alignment needs to be conducted once when cutting and marking are conducted every time, the automatic slicing machine has the advantages that the efficiency in the whole cutting and marking process is greatly improved, the cutting and marking accuracy is also greatly improved, and the application range is wider compared with a slicing machine achieving semi-automatic cutting by setting a cutting interval.

Description

technical field [0001] The invention belongs to the technical field of single-photon detection, and in particular relates to an automatic slicer for preparing single-photon detectors. Background technique [0002] A single photon detector is a device that is extremely sensitive to single quantum substances such as photons. It has a wide range of applications in physics, astronomical photometry, optical time domain reflectometry (OTDR), quantum key distribution system (QKD) and other fields. Since these detectors work in a temperature range below 1K, compared with ordinary semiconductor photon detectors (such as photomultiplier tubes and avalanche photodiodes), they are characterized by their unique high detection sensitivity and low background noise. , low dark count rate and fast signal response speed have become the best among photon detectors. [0003] In recent years, a transition-edge sensor (Transition-Edge Sensors, TES) based on superconducting critical state transi...

Problems solved by technology

Since the silicon substrate has a certain thickness and high hardness, it is difficult to cut directly. In the process of cutting the above-mentioned superconducting film into small pieces, it is generally used to align the cutting position under the microscope and cut manually, which is inefficient and the scribing effect is low. Poor, not easy to align; some first determine the initial cutting position, and then realize semi-automatic cutting by setting the cutting distance, it is difficult to achieve fully automatic cutting
