Abstract
Description
The present invention relates to a support pin assembly, and more particularly, to a support pin assembly for a baking apparatus that supports a wafer substrate in a baking process during semiconductor manufacturing.
Photolithography is a technique for transferring a shadow produced by irradiating light onto a mask substrate having a circuit pattern formed thereon and transferring the shadow onto a wafer, and is a process for forming a pattern designed on a wafer in a semiconductor manufacturing process.
Materials used in semiconductor devices are not exposed to light, and their characteristics are not changed. In order to transfer the circuit design of the mask master plate to the wafer through an exposure process, a medium is required. The medium is called a photoresist (PR). A photoresist refers to a material that receives light of a specific wavelength and can selectively remove a light-receiving portion and a non-light-receiving portion during a subsequent development process by using a property that the solubility of the developer is changed.
Photolithography processes include coating, soft bake, exposure and post exposure, development, and hard bake processes.
Here, the soft bake process is performed at a low temperature to remove the organic solvent remaining in the photoresist after the coating process, to prevent the exposure facility and the mask contamination due to the residual solvent, and to maintain the photoresist reaction characteristic constant. By heating to about 110 ° C, the solvent is removed and the density of the photosensitizer is increased to reduce the sensitivity to environmental changes.
After the soft bake process, the wafer and the mask are precisely aligned and the exposure process proceeds. After the exposure, the wafer is baked again. The post exposure bake (PEB) is a very important process for pattern formation through the diffusion of the photoresist. In particular, in the case of ArF PR using 193 nm wavelength, a chemical amplified resist (CAR) is often used. In this case, since the chemical amplification reaction occurs through the PEB process, the influence of the PEB temperature on the sensitivity of the photosensitizer very big.
When the development is complete, remove the developer and finally perform a hard bake as necessary. First, the photosensitive agent is thoroughly rinsed with DI water to remove the remaining photosensitive agent, followed by drying. Then, the photosensitive agent is baked at a temperature slightly higher than the glass transition temperature of the photosensitive agent so that the photosensitive agent is not deformed.
Korean Patent Publication No. 2002-0080593 discloses a "baking apparatus for semiconductor device manufacturing" in connection with the baking process for manufacturing such a semiconductor, and specifically, it is installed at each corner inside the chamber for performing the baking process A heater that heats the inside of the chamber, a temperature sensor that is installed at each corner of the chamber to detect the temperature inside the chamber, and a power supply to the heater by analyzing the temperature inside the chamber by the temperature sensing signal of the temperature sensor And three tapered pins for supporting the wafer in the lower part of the chamber. In this baking apparatus, the wafer is heated by convection of air by providing a heater at each corner inside the cubic chamber, Uneven heating of the wafer, which can occur when a bake plate is used, The risk of contamination of the image and the operator due to the contact failure of the bake plate and wafer on the baking process, discloses that it is possible to prevent that.

In this way, in the baking process, a support pin, which is generally pointed upward and supports the wafer substrate, is usually made of carbon, and wear and particles are generated at the top end portion and the bottom fixing portion, There is a problem that the wafer substrate is damaged and defective.
Particularly, when a shock occurs due to malfunction of the manufacturing apparatus during the baking process, the sharp upper end of the support pin applies a strong impact to the wafer substrate, thereby causing a problem that the substrate is broken or damaged. There has been a problem that the pin is deformed, leaving a mark on the wafer substrate.
