[0001] The present invention relates to a photocurable composition, and in particular to a photocurable composition suitable for forming a photocurable layer for inkjet compatible planarization. [Background technology]

[0002] Inkjet adaptive planarization (IAP) is a process of planarizing the surface of a substrate, e.g., a wafer containing electrical circuitry, by jetting droplets of a photocurable composition onto the surface of the substrate and directly contacting the applied liquid with a planar superstrate to form a planar liquid layer. The planar liquid layer is typically cured by exposure to UV light, and after removal of the superstrate, a planar polymer surface is obtained that can be subjected to subsequent processing steps, e.g., baking, etching, and / or further deposition steps.

[0054] The substrate and solidified layer may be subjected to additional processing, such as an etching process, to transfer an image corresponding to the pattern of one or both of the solidified layer and / or the patterned layer underlying the solidified layer to the substrate. The substrate may be further subjected to known steps and processes for device (article) manufacturing, including, for example, curing, oxidation, layering, deposition, doping, planarization, etching, formable material removal, dicing, bonding, and packaging.

[0055] The photocurable layer may be used as an interlayer insulating film in semiconductor devices such as LSI, system LSI, DRAM, SDRAM, RDRAM, and D-RDRAM, or as a resist film used in the semiconductor manufacturing process.

[0056] As further demonstrated in the examples, monomers corresponding to the chemical structure of formula (1) or (2) can have the advantages of high carbon content, low vapor pressure, and low viscosity, thereby making them suitable for inclusion in photocurable compositions compatible with IAP or NIL processing. The photocurable compositions can be used to form photocurable layers with only minor loss of monomer due to evaporation, resulting in photocurable layers with uniform structure, high etching resistance, and high thermal stability. Working Example

[0057] The following non-limiting examples illustrate the concepts described herein.

[0058] Example 1

[0059] Comparison of properties of first polymer examples

[0060] Table 1 includes representative monomers (11-17) that all conform to the structures of formulas (1) and (2), along with their calculated carbon content and calculated vapor pressure. It can be seen that the carbon content of the listed monomers 11-17 is greater than about 86%. When the two phenyl groups are directly bonded, the carbon content is greater than 92%.

[0061] Furthermore, the calculated vapor pressures for monomers 11-17 are below 0.0005 mmHg.

[0062] In contrast, benzyl acrylate (BA) and divinyl benzole (DVB), typical monomers for use in resist compositions in IAP and NIL processes, do not have this combination of high carbon content and low vapor pressure. Both DVB and BA have much higher vapor pressures, and BA has a much lower carbon content.

[0063] [Table 1]

[0064] photocurable composition

[0065] A series of photocurable compositions were prepared containing various amounts of monomers as shown in Table 1. The components of the polymerizable materials are outlined in Tables 2 and 3.

[0066] [Table 2]

[0067] [Table 3]

[0068] All photocurable compositions contained 1 wt% surfactant and 2 wt% photoinitiator next to the polymerizable material. Diacrylate A was m-xylylene diacrylate, diacrylate C was 5-ethenyl-1,3-phenyl acrylate, and triacrylate B was trimethylolpropane triacrylate.

[0069] From Tables 2 and 3, it can be seen that the presence of small amounts of monomers described herein as "at least one first polymerizable monomer" conforming to the general structure of Formula (1) or Formula (2) can result in an increase in the calculated carbon content of the polymerizable material of 2 percent or more. The carbon content of the polymerizable material was calculated based on the known molecular weight and amount of monomer of the polymerizable material. Furthermore, it was observed that the addition of monomers conforming to Formulas (1) and (2) does not adversely affect the viscosity, and does not result in an undesirable increase in viscosity above 50 mPa·s at 23° C.

[0070] It may further be observed that photocured layers made from the photocurable compositions may have increased thermal decomposition temperatures as compared to photocured layers formed from respective photocurable compositions that do not include one of the monomers 11-17 listed in Table 1.

[0071] The photocured layers were prepared by adding the respective resist composition between two glass slides, which had a distance of 300 microns from each other. The resist between the glass slides was photocured by applying 2.4 J of radiation energy. The photocured layers were analyzed by thermal analysis (TGA). TGA was performed using a LINSEIS STA PT1000 instrument (Linseis Messgeraete GmbH, Germany). All measurements were performed under nitrogen at a rate of 5 liters / h. The samples (approximately 25 mg per test) were heated at a rate of 20 °C / min and the weight loss was continuously recorded.

[0072] The TGA curves of some representative photocurable layer (S16, S17, and S18) and comparative photocurable layer C1 materials are shown in FIG. 1. It can be seen that all of the analyzed materials shown had decomposition temperatures above 350° C., except for C1. Furthermore, it can be seen that the addition of small amounts of the disclosed biphenyl-monomers can increase the thermal decomposition temperature of the materials. For example, a 10 wt % amount of monomer 16 (sample S16) can increase the thermal decomposition temperature of the respective composition C1 (containing only diacrylate-A) by about 30° C.

[0073] As used herein, thermal degradation temperature refers to the initial degradation temperature T(X), which is the temperature in the TGA curve where the deviation of the curve from a nearly linear plateau shape is first observed immediately prior to a rapid loss in mass of the sample, i.e., degradation.

[0074] Viscosity measurement

[0075] The viscosities of samples C1-C4 and S16-S18 were measured using a Brookfield DV-11+Pro viscometer with spindle #18. For each viscosity measurement, 6-7 ml of sample was taken, added to the sample chamber, and allowed to equilibrate for 15-20 minutes until the target temperature of 23°C was reached. Viscosity was measured at a speed of 135 rpm with spindle #18. For each sample, measurements were repeated three times and the average value was calculated.

[0076] The viscosities of samples S1 to S13 were calculated according to the following formula.
