Description

本発明は、レジスト塗布基板の熱処理方に関する。
The present invention relates to a resist coating heat treatment how the substrate.

フォトレジストを露光する処理後に、現像する処理を行うレジストパターンを形成するフォトプロセス法の技術は、様々な分野で用いられている。   A technique of a photo process method for forming a resist pattern for performing a developing process after a process of exposing a photoresist is used in various fields.

特に電子産業界においては、半導体装置の集積回路を形成したり、液晶パネル装置のパネル画素を形成する際に使用されている。   Particularly in the electronic industry, it is used when forming an integrated circuit of a semiconductor device or forming a panel pixel of a liquid crystal panel device.

近年では、半導体装置産業においては、その集積度が進むにつれ、回路線幅が微細となり、配線密度が増加となり、現像処理での品質管理もいっそう厳しい品質精度を要求されている。   In recent years, in the semiconductor device industry, as the degree of integration has progressed, the circuit line width has become finer, the wiring density has increased, and stricter quality control is required for quality control in development processing.

一方、露光処理後、現像処理の前処理として、PEB(Post Exposure
Bake、露光後焼きしめ)と呼ばれる熱処理があり、その処理を経て,現像処理が行われる。
On the other hand, after exposure processing, as pre-processing for development processing, PEB (Post Exposure)
There is a heat treatment called “Bake, post-exposure baking”, and after that processing, development processing is performed.

従来の現像処理においては、露光処理後のレジストの表面に直接に親水性の現像液を噴射する場合、現像液のレジストに対する濡れ性が低いことに起因して、レジスト溶解性の不具合による現像不良を引き起こす恐れがあり、親水性の現像液を付与する量の制御及び方法に問題がある(特許文献1、2参照)。   In conventional development processing, when a hydrophilic developer is sprayed directly onto the resist surface after exposure processing, poor development due to poor resist solubility due to low wettability of the developer to the resist. There is a problem in the control and method of the amount of hydrophilic developer applied (see Patent Documents 1 and 2).

その対策として、界面活性剤を添加した現像液を用いており、その場合には、レジストの断面形状、微小な点欠陥の現像制御が困難となる問題がある(特許文献3参照)。   As a countermeasure, a developer added with a surfactant is used. In this case, there is a problem that it becomes difficult to control the development of the resist cross-sectional shape and minute point defects (see Patent Document 3).
