Description
The present invention relates to a method of forming a resist pattern on a substrate using a photosensitive resin laminate obtained by laminating a photosensitive resin composition that can be developed with an alkaline aqueous solution on a support layer, the photosensitive resin laminate, and the use of the resist pattern. It is about. More specifically, manufacturing of printed wiring boards, manufacturing of flexible printed wiring boards, manufacturing of IC chip mounting lead frames (hereinafter referred to as lead frames), precision machining of metal foil such as metal mask manufacturing, BGA (ball grid array) or CSP Manufacture of semiconductor packages such as (chip size package), manufacture of tape substrates represented by TAB (Tape Automated Bonding) or COF (Chip On Film) The photosensitive resin composition which provides a resist pattern suitable for manufacture of a member, such as an ITO electrode, an address electrode, or an electromagnetic shield in the field of flat panel displays.
The conventional printed wiring board is manufactured by the photolithographic method. The photolithography method applies a photosensitive resin composition onto a substrate, performs pattern exposure, polymerizes and hardens the exposed portion of the photosensitive resin composition, removes the unexposed portion with a developer, forms a resist pattern on the substrate, and performs etching or plating treatment. After forming a conductor pattern, the resist pattern is peeled off from the board | substrate, and the method of forming a conductor pattern on a board | substrate is said.
In said photolithographic method, when apply | coating a photosensitive resin composition on a board | substrate, the method of apply | coating and drying a photoresist solution to a board | substrate, or the layer which consists of a support layer and the photosensitive resin composition (henceforth a "photosensitive resin layer" is also called. ) And the method of laminating | stacking the photosensitive resin laminated body (henceforth a "dry film resist") which laminated | stacked the protective layer sequentially according to necessity on a board | substrate. And in manufacture of a printed wiring board, the latter dry film resist is used in many cases.
The method of manufacturing a printed wiring board using said dry film resist is easily described below.
First, when a dry film resist has a protective layer, for example, a polyethylene film, it peels this from the photosensitive resin layer. Subsequently, using a laminator, a photosensitive resin layer and a support layer are laminated | stacked on a board | substrate, for example, a copper clad laminated board, in order of the board | substrate, the photosensitive resin layer, and a support layer. Subsequently, an exposure part is polymerized and hardened | cured by exposing the photosensitive resin layer to the ultraviolet-ray which contains the i line | wire (365 nm) which an ultrahigh pressure mercury lamp emits through the photomask which has a wiring pattern. The support layer, for example polyethylene terephthalate, is then peeled off. Subsequently, the unexposed part of the photosensitive resin layer is melt | dissolved or disperse | dissolved by the developing solution, for example, the aqueous solution which has weak alkalinity, and a resist pattern is formed on a board | substrate.
There are two methods for producing a metal conductor pattern using the resist pattern on the substrate thus formed, and there are two methods. A method of removing a metal part not covered with a resist by etching and attaching a metal by plating. There is a way to. In particular, in recent years, the former method is widely used in the simplicity of the process.
In the method of removing a metal part by etching, the metal in the hole is not etched by covering the through hole (through hole) of the substrate or the via hole for interlayer connection with a cured resist film. This method is called tenting method. In the etching step, for example, a cupric chloride, ferric chloride or copper ammonia complex solution is used.
With recent miniaturization of wiring intervals in printed wiring boards, high resolution and high tentability are required for dry film resists in order to manufacture narrow pitch patterns at a good production rate. As a method of increasing the resolution, the dry film resist can be increased simply by thinning, while the drag on the physical external force of the film due to the spraying of the developing process and the etching process is weakened. The problem was that the via hole could not be protected (the tentability was not good).
Patent document 1 has the indication of the outstanding photoresist by having many trifunctional monomers in the unsaturated compound in the photosensitive resin composition. However, it only describes the ratio of the trifunctional monomer in an unsaturated compound, and there existed a problem that tentability was not excellent in a certain range. About patent document 1, it mentions later in a comparative example.
Patent Literature 2 discloses an excellent photoresist with a tetrafunctional monomer as an unsaturated compound in the photosensitive resin composition. However, there existed a problem that tent property was not excellent in the direct drawing exposure using these.
Patent Document 3 discloses an excellent photoresist with a trifunctional monomer in an unsaturated compound in the photosensitive resin composition. However, there was a problem that the tentability was not excellent in the direct drawing exposure by the thin film using these.
However, when these polyfunctional monomers are contained in a large amount in the photosensitive resin composition, there also existed a problem that oily aggregates generate | occur | produce at the time of image development.
Therefore, also in direct drawing exposure, it was desired that tent property was favorable, that the aggregate at the time of image development is not oily, and there was also little powdery aggregate.
Even when the thickness of the photosensitive resin layer is thin to 3 to 15 µm, the photosensitive resin laminate has a good tentability even when exposed by direct drawing exposure, and no oily aggregates are generated at the time of development, and the powdery aggregates are also less. The purpose is to provide a sieve.

It is preferable to add to the photosensitive resin composition so that the viscosity of the photosensitive resin composition solution apply | coated on a support layer may be 500-4000 mPa at 25 degreeC.
<Resist Pattern Forming Method>
The resist pattern using the photosensitive resin laminated body of this invention can be formed by the process including a lamination process, an exposure process, and a developing process. An example of the specific method is shown below.
As the substrate to be processed, a copper clad laminate is used for the purpose of manufacturing a printed wiring board, and a glass substrate such as a substrate for a plasma display panel, a surface electrolytic display substrate, an organic EL sealing cap, or a through hole is used for the purpose of manufacturing the uneven substrate. The formed silicon wafer and the ceramic base material are mentioned. Plasma display base material is a base material which formed an electrode on glass, apply | coated a dielectric layer, apply | coated the partition glass paste, and sand blasted the partition glass paste part, and formed the partition. The sand-blasted process of these to-be-processed base materials turns into an uneven base material.
First, the lamination process is performed using a laminator. When the photosensitive resin laminated body has a protective layer, after peeling a protective layer, a photosensitive resin layer is heat-compressed and laminated | stacked on the surface of a to-be-processed base material with a laminator. In this case, the photosensitive resin layer may be laminated only on one surface of the substrate surface or may be laminated on both surfaces. The heating temperature at this time is generally 40-160 degreeC. In addition, the adhesion and chemical resistance are improved by performing the heat pressing twice or more. At this time, crimping | bonding may use the two-stage laminator provided with two rolls, and may make it crimp by passing through a roll several times.
Next, an exposure process is performed using an exposure machine. If necessary, the support is peeled off, passed through a photomask, and exposed with actinic light. The exposure amount is determined in accordance with the light source illuminance and the exposure time. You may measure using a photometer.
Moreover, in an exposure process, you may use the direct drawing exposure method. Direct drawing exposure is a system which draws and exposes directly on a board | substrate, without using a photomask. As the light source, for example, a semiconductor laser having a wavelength of 350 to 410 nm or an ultrahigh pressure mercury lamp is used. The drawing pattern is controlled by a computer, and the exposure amount in this case is determined according to the illuminance of the light source and the moving speed of the substrate.
Next, a developing process is performed using a developing apparatus. When a support exists on the photosensitive resin layer after exposure, it removes as needed and then develops and removes an unexposed part using the developing solution of aqueous alkali solution, and obtains a resist image. As the aqueous alkali solution, an aqueous solution of Na 2 CO 3 or K 2 CO 3 is used. They are selected according to the properties of the photosensitive resin layer, and is generally an aqueous solution of Na 2 CO 3 concentration of 0.2 to 2 mass%, 20 ~ 40 ℃. In the alkaline aqueous solution, a small amount of an organic solvent for promoting the surface active agent, the antifoaming agent and the development may be mixed.
Although a resist pattern is obtained by the above-mentioned process, in some cases, the heating process of 100-300 degreeC can also be performed further. By performing this heating process, further chemical-resistant improvement is attained. For heating, hot air, infrared or far-infrared furnaces are used.

In Comparative Example 1, when a polymer having a weight average molecular weight of less than 70,000 was used as the alkali-soluble resin, an oily aggregate was generated at the time of development and a problem occurred.
In the comparative example 2, the ratio of the compound represented by the said General formula (II) in the photosensitive resin composition was less than 30 mass%, and the tent property fell.
In the comparative example 3, the ratio of the compound represented by the said general formula (II) in the photosensitive resin composition is more than 55 mass%, and the ratio of said (a) alkali-soluble resin with respect to the whole amount of photosensitive resin composition is A mass%, When the ratio of the compound (b) having a unsaturated double bond capable of photopolymerization was B mass%, A / B was less than 1.1, resulting in deterioration of the tentability. The comparative example 4 is a follow-up of Unexamined-Japanese-Patent No. 11-119422. In the comparative example 4, since the polyfunctional photopolymerizable unsaturated compound which does not correspond to the compound represented by the said General formula (I) and the compound represented by the said General formula (II) was not used, tent property deteriorates and an oily aggregate is bad. This result was generated.
