or choline aqueous solution is used, especially during semiconductor manufacturing. Furthermore, as a developing solution with improved process tolerance, a method using an aqueous solution of methyltriethanolammonium hydroxide is known (Japanese Patent Application Laid-open No. 74432/1983). Furthermore, a method using an aqueous solution of dialkoxy γ-alkyl ammonium hydroxide as a developer with improved stability of choline is also known (Japanese Patent Laid-Open No. 143019/1983).

ない問題が生ずる。By the way, when forming fine resist patterns such as those for VLSI, conventional methods cause a phenomenon in which the resist that should originally be removed by the developer remains in the exposed area without being removed, so-called "scum". An undesirable problem arises.

LSIの構成素子間の特性ばらつきを減少でき、LSI
の性能向上とコスト低減につながる。Furthermore, VLSI includes processes that require strict dimensional control, such as gate processes, and accuracy and reproducibility of resist pattern dimensions are important. In other words, the use of reduction projection exposure equipment (steppers) has become commonplace in VLSIs, and this reduction projection exposure method is affected by standing waves, reducing dimensional accuracy. Characteristic variations between LSI components can be reduced, and LSI
This leads to improved performance and reduced costs.

自動現像機で現像する。A positive photoresist is applied to a silicon wafer using a spin coater or the like, and then prebaked using a direct contact hot plate to obtain a solvent-free coating film. Next, exposure is performed by a stepper through a reticle on which a desired mask pattern has been drawn. The reticle consists of lines and spaces that consist mainly of specially designed punched patterns (the back grout is the unexposed area and the resist film remains), and lines and spaces that mainly consist of the left pattern (the bank ground remains). Use a reticle with a pattern (the resist film is removed in the exposed area). Next, the exposed wafer is developed using an automatic developer using the developer of the present invention.

い。The portions solubilized by exposure are selectively dissolved and removed, resulting in a positive image in which the mask pattern is faithfully reduced. The obtained image was scanned using a scanning electron microscope (SEM).
In addition, the extraction sensitivity (the exposure amount when the space part of the punching pattern reaches the mask dimension considering the reduction rate) and the remaining sensitivity (the line part of the remaining pattern takes into account the reduction rate) Measure the exposure amount (when the mask size is reached). The quality of dimensional controllability is determined by taking the difference between the leaving sensitivity and the punching sensitivity. The smaller this difference is, the better the dimensional controllability is.
