Embodiment

[0269] The present invention will be described below by way of various examples. Aspects of the invention are not limited to these examples.

[0270] Synthesis of Polymer 1

[0271] Add 350g PGMEA in the three-necked flask, then add the following MOI-BP (Karenzu MOI-BP, Showa Denko) 32.79g, McHN (Kawasaki Chemical Industry) 20g, DYE-M9A (Osaka Shinyaku) 6.422g, HPMA (Light Ester HOP, Kyoeisha Chemical) 8.16g. They correspond to unit (a), unit (b), unit (c) and unit (d), respectively.

[0272]

[0273] Furthermore, V-601 / oil-soluble azo polymerization initiator (Fujifilm Wako Pure Chemical Industries, Ltd.) was added. Charge nitrogen into the three-necked flask, cover the lid, heat while stirring, and react at 80° C. for 4 hours. Additionally, 3 g of PGME was added and stirred to complete the polymerization. The reaction solution was brought back to room temperature. The reaction solution was added dropwise to 1500 g of hexane to precipitate a polymer. It was filtered...

Description

technical field [0001] The present invention relates to a polymer containing a specific structural unit, and a semiconductor composition containing the polymer. In addition, the present invention relates to a film using the semiconductor composition and a method for manufacturing a device. Background technique [0002] In the manufacturing process of devices such as semiconductors, fine processing is usually performed by photolithography using photoresists. The process of microfabrication is to form a thin photoresist layer on a semiconductor substrate such as a silicon wafer, cover this layer with a mask pattern corresponding to the pattern of the device targeted at this layer, and activate it with ultraviolet light or the like through the mask pattern. This layer is exposed to light, a photoresist pattern is obtained by developing the exposed layer, and the substrate is etched using the obtained photoresist pattern as a protective film, thereby forming fine unevenness cor...
