Core Viewpoint - The article provides an in-depth analysis of photoresists, focusing on their types, compositions, and the processes involved in their application in semiconductor manufacturing. Group 1: Types of Photoresists - Positive photoresists undergo a decomposition reaction upon exposure to light, resulting in high resolution and good contrast, but they have lower adhesion and higher costs [3][8]. - Negative photoresists form a cross-linked structure upon exposure, which enhances adhesion and etch resistance, but can lead to deformation during development [3][37]. Group 2: Composition of Positive Photoresists - The main component of positive photoresists is phenolic resin, which is soluble in alkaline developers and can be easily cross-linked through thermal reactions [12][35]. - The average molecular weight of the resin typically ranges from 1000 to 3000 g/mole, consisting of 8 to 25 repeating units [17]. Group 3: Development Process - The development process for positive photoresists involves using alkaline developers, which are often based on sodium hydroxide or potassium hydroxide solutions [94]. - The choice of developer is crucial, as it must be compatible with the photoresist to ensure effective development without residue [102][106]. Group 4: Process Conditions - Recommended process conditions for applying photoresists include specific spin speeds and baking temperatures to achieve desired film thickness and uniformity [62][73]. - The article emphasizes the importance of controlling environmental factors such as humidity and temperature during the photoresist application process to avoid defects [78][113]. Group 5: Sensitivity to Environmental Factors - Positive photoresists are particularly sensitive to humidity, which can affect their performance during the development process [25][36]. - The article discusses the impact of temperature on the development rate, highlighting the need for precise control to avoid underdevelopment or overdevelopment [113][116]. Group 6: Conclusion - The article concludes that understanding the properties and processes of photoresists is essential for optimizing semiconductor manufacturing and achieving high-quality results [1][10].
