Problems solved by technology

[0003] Generally, a positive type photoresist whose solubility to an alkaline developing solution is increased by exposing the resist pattern is often used, but the positive type photoresist has the following problems: Naphthoquinone diazide sulfonic acid used as a photosensitive agent produces sulfonic acid, which corrodes the metal wiring
[0010] However, in both of these patent documents 1 and 2, there is a problem that since the terminal of the obtained organopolysiloxane compound has a condensable functional group, it may change over time.

Abstract

The present invention provides an organopolysiloxane compound and an active energy ray curable composition containing the same, particularly organopolysiloxane compound which is excellent in crack resistance, has a small change in hardness over time, and can be cured by an alkali development, and an active energy ray-curable composition which contains the organopolysiloxane compound and which canbe used as a negative resist material. The organopolysiloxane compound includes structural units shown as formulae (I) to (III), wherein the ratio of the total number of alkoxy and hydroxyl groups directly bonded to silicon atoms to the number of the silicon atoms is 0.3 or less; R1 and R4 represent a hydrogen atom, a methyl group, an ethyl group, a n-propyl group or an isopropyl group; R2 and R5represent a divalent hydrocarbon group having 1 to 10 carbon atoms; R3 represents a hydrogen atom or a methyl group; and R6 represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a phenyl group, a (meth)acryloxypropyl group or a glycidoxypropyl group; n represents an integer satisfying 0 <= n <= 2; and m represents an integer satisfying 0 <= m <= 2.

Description

technical field [0001] The present invention relates to an organopolysiloxane compound and an active energy ray-curable composition containing the same, and more specifically, to an organopolysiloxane compound having an alkali-soluble site and an active energy ray-curable composition containing the same. Background technique [0002] With the increase in integration and speed of LSIs, it is necessary to reduce the size of resist patterns in the manufacturing process of semiconductor devices. [0003] Generally, a positive type photoresist whose solubility to an alkaline developing solution is increased by exposing the resist pattern is often used, but the positive type photoresist has the following problems: Naphthoquinonediazidesulfonic acid used as a photosensitive agent produces sulfonic acid, which corrodes metal wiring. [0004] On the other hand, such a problem does not occur in a negative photoresist that uses a mixture of a photocurable resin and an alkali-soluble r...
