[Industrial Application Field] The present invention relates to a positive photosensitive heat-resistant material having novel positive photosensitive characteristics. [Prior art] Conventionally, as a photosensitive heat-resistant resin, (1) a mixture of polyamic acid and dichromate (Japanese Patent Publication No. 1973-
17374) (2) Photosensitive polyamide synthesized from pyromellitic acid derivatives (Japanese Patent Application Laid-open No. 115541/1982) (3) Mixture of polyamic acid and unsaturated amine (Japanese Patent Application Laid-open No. 145794/1989) (4) ) Reaction product of polyamic acid and unsaturated epoxy (JP-A-55-45746) (5)
Various proposals have been made, such as a mixture of polyamic acid and an amine containing an azide group (Japanese Unexamined Patent Publication No. 58-67724). [Problems to be Solved by the Invention] However, all of the above-mentioned materials have negative photosensitive characteristics. Negative photosensitive resins are those in which a soluble resin is photo-crosslinked to become insolubilized, and developed and patterned using the difference in solubility between the resin and the unexposed area. If the photocrosslinking reaction can occur completely, it is possible to create a good solubility difference between the exposed and unexposed areas, but it is usually difficult to cause this reaction to occur completely. Therefore, in the development process for washing out the unexposed areas, the insufficiently crosslinked parts of the exposed areas are partially washed out, which causes film roughening on the surface. Furthermore, negative photosensitive resins form images by causing a photocrosslinking reaction to insolubilize the resin that dissolves in the developer, and in this development process, the crosslinked areas (exposed areas) are removed. Swelling caused by the developer cannot be avoided. As a result, pattern disturbances and peeling may occur due to this.
This not only reduces the reliability of image formation, but is also extremely disadvantageous in forming high-resolution images. This invention was made to solve these problems, and it is an object of the present invention to obtain a positive photosensitive heat-resistant material that can be patterned with direct light and electron beams, has no pattern disturbance, and has high heat resistance and high resolution. With the goal. [Means for solving the problems] The positive photosensitive heat-resistant material of the present invention has the general formula (In the formula, R 1 is a divalent organic group, R 2 is a tetravalent organic group,

m represents any positive integer. ) Contains the polymer shown below. [Function] Since the photosensitive heat-resistant material of the present invention is a positive type, it does not swell due to developer and has high resolution. Weight change during curing is reduced, so there is no pattern disturbance, and furthermore, it can be imidized by heating. High heat resistance. [Example] The positive photosensitive heat-resistant material of the example of this invention is
It is preferable to contain 20 to 90 parts by weight of the polymer represented by general formula (1) and 10 to 80 parts by weight of the polymer represented by general formula (2).
