Company patents
GUDENG PRECISION INDUSTRIAL CO., LTD.
GUDENG PRECISION INDUSTRIAL CO, LTD. demonstrates a primary focus on semiconductor technologies, with "Semiconductor Manufacturing Process" accounting for 55.7% of its portfolio and "Photolithography" for 29.9%, showing a consistent, albeit fluctuating, commitment to these core areas, with Photolithography patents growing by 25.0% so far in 2026. Surprisingly, despite its semiconductor dominance, the company also shows a significant, albeit volatile, interest in "Containers & Packaging," which surged by 900.0% in 2024 before declining by 40.0% in 2025 and 66.7% so far in 2026, suggesting a brief but intense diversification or a strategic pivot that has since shifted.

Systems and methods for automated substrate transport, precise positioning, temperature regulation, and chamber environment management to ensure process stability, uniformity, and yield in semiconductor manufacturing.
Methods for temporarily attaching a wafer or substrate to a carrier for thinning, dicing, or other processing, followed by controlled debonding, often using light-sensitive resins, temporary adhesives, or roughened interfaces.
Methods and equipment for applying photoresist uniformly onto wafers, forming patterns through various exposure techniques (e.g., direct imaging, multi-exposure), and integrating patterned layers into semiconductor structures or packaging.
Specialized cleaning techniques and apparatus designed for removing microscopic contaminants, residues, or films from sensitive substrates, such as semiconductor wafers or flat panel displays, often involving chemical, mechanical, or plasma-based methods.
Locking mechanisms specifically designed for automotive applications, recreational vehicles, or unique door types like bi-fold, sliding, or container doors, often incorporating specific safety, noise reduction, or operational features.
Components, processes, and methods specifically designed for Extreme Ultraviolet (EUV) lithography, including light sources, reflective optics, masks, pellicles, and contamination control mechanisms.
Techniques and apparatus for electrically testing semiconductor devices, integrated circuits, or wafers during manufacturing or post-assembly, including built-in self-test (BIST) and contact reliability assessment.
Mechanical lock designs and components focused on resisting picking, unauthorized manipulation, forced entry, or other technical unlocking methods, often through complex internal mechanisms or robust materials.
Minimally invasive medical devices, typically flexible tubes, inserted into body lumens to deliver substances, remove obstructions, or perform localized treatments like ablation, dialysis, or drainage.
Innovations in the design, materials, and manufacturing of lithography masks, including reflective masks, programmable masks, and defect mitigation strategies, to enable finer feature patterning and process control.
Technologies for removing contaminants from critical surfaces of sensors, vehicle parts, or industrial components, often involving automated or semi-automated processes. This can include physical, acoustic, or fluid-based methods to maintain functionality.
Containers or packaging components featuring active mechanisms for controlled release, preparation, or delivery of their contents, such as liquids, bulk materials, volatile compounds, or single-serve portions.
Locks integrating electronic components for remote control, wireless communication, internet connectivity, and digital credential management, often including features for user identification and access monitoring.
