Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing equipment, specifically to an environmental temperature and humidity control component for a coating and developing machine. Background Technology

[0002] Photoresist coating and developing machines are critical equipment in semiconductor wafer manufacturing. The temperature and humidity environment within their working chamber directly affects the uniformity of photoresist coating and the developing resolution. Existing photoresist coating and developing machines often employ a single sensor and regulating element for temperature and humidity control, with arbitrary placement of these elements. This results in uneven temperature and humidity distribution within the working chamber, with localized temperature and humidity deviations exceeding process requirements (temperature fluctuation ±0.5℃, humidity fluctuation ±2% RH), thereby impacting wafer production quality.

[0003] Furthermore, the existing regulating device has structural design flaws: for example, heating and cooling elements are directly exposed inside the working chamber, making them prone to interference with the wafer; airflow circulation relies on a simple fan without a guiding structure, resulting in numerous airflow dead zones; and the wiring connections between modules are messy and lack protection, making them susceptible to poor contact due to equipment vibration. These structural deficiencies reduce the stability and reliability of the regulating device, making it difficult to meet the requirements of high-precision semiconductor manufacturing. Therefore, it is necessary to optimize the module layout, installation method, and connection structure of the temperature and humidity control components from a structural design perspective, solve the problems existing in the current device, and improve the process stability of the coating and developing machine. Summary of the Invention

[0004] The purpose of this invention is to provide an environmental temperature and humidity control component for a coating and developing machine. This component has the advantages of achieving uniform temperature and humidity control within the working chamber through reasonable structural design and modular assembly, thereby improving control accuracy and device stability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A temperature and humidity control component for a coating and developing machine is characterized by comprising a working chamber, a temperature and humidity detection module, a control module, a temperature control module, a humidity control module, and an airflow circulation module. The working chamber is a hollow rectangular structure with an airflow channel on one side wall, the two ends of which are connected to the interior of the working chamber. The temperature and humidity detection module includes four temperature and humidity sensors, which are fixed to the four corners of the inner wall of the working chamber by bolts. The detection ends of the temperature and humidity sensors face the interior of the working chamber, and the signal output ends extend to the control module via wires. The control module is fixed to the outer wall of the working chamber, and a touch screen is provided on its surface. The control module also includes a controller that is electrically connected to the temperature and humidity sensors, the temperature control module, the humidity control module, and the airflow circulation module via wires.

[0006] Further configuration: The temperature regulation module includes a heating unit and a cooling unit. The heating unit is a U-shaped PTC heating tube, and the cooling unit is a sheet-like semiconductor cooling chip. The cooling unit is fixed in the middle of the airflow channel by screws.

[0007] Further configuration: The humidity control module includes a humidification unit and a dehumidification unit. The humidification unit is an ultrasonic atomizer, whose atomization outlet extends into the airflow channel through a silicone tube. The humidification unit is fixed to the outer wall of the working chamber by a bracket and is located above the airflow channel. The dehumidification unit is a plate-shaped condenser dehumidifier, which is vertically embedded at the outlet of the airflow channel. The drain outlet of the dehumidification unit extends to the outside of the working chamber through a drain pipe.

[0008] Further configuration: The airflow circulation module includes a circulating fan and an airflow guide plate. The circulating fan is fixed to the center of the top of the working chamber by bolts, and its air outlet faces the inside of the working chamber. The airflow guide plate is a circular metal plate, which is fixed directly below the circulating fan by a connecting rod.

[0009] Further configuration: The airflow guide plate is provided with multiple guide holes evenly distributed in a ring array.

[0010] Further configuration: The working cavity also includes an alarm module, which is an audible and visual alarm, fixed to the top of the control module with screws, and the signal input terminal of the alarm module is electrically connected to the controller via a wire.

[0011] Further features: The outer casing of the alarm module is equipped with a warning light and a buzzer.

[0012] In summary, this utility model has the following beneficial effects: The temperature and humidity detection module accurately collects temperature and humidity data within the working chamber, and combined with intelligent control, achieves independent and precise adjustment of temperature and humidity, effectively solving the problem of large temperature and humidity fluctuations in existing photoresist coating and developing machines. This ensures uniform photoresist coating and developing accuracy.
