Description of the invention: [Technical field to which the invention belongs] The present invention relates to semiconductor processing technology, and more particularly, to an electronic device having improved adhesion quality such as a semiconductor garment and a device for manufacturing an organic layer including adhesion enhancement. Methods. [Prior art] Using the method of mesh uranium, the organic material layer is adhered to the substrate with a low surface energy material layer (such as Tefl (PTFE) AF®) on the surface in a photoresistive form, and Low surface energy materials do not adhere sufficiently to the surface of a substrate. As a result, the quality of lithography is reduced and it is not possible to incorporate low surface energy materials into the layers of a multilayer device. There have been several attempts to increase the adhesion of organic materials such as Niu to various substrates with a recording surface as the top surface. Due to the lack of pre-treatment, organic photoresist materials will not wet low surface energy surfaces and therefore will not coat these surfaces in a manner that facilitates patterning. Although many surface preparation options have been utilized, it has been proven that these conventional procedures cannot achieve the adhesive durability required to complete all necessary processing steps. Some of these procedures have worked, which are short in nature, while for the remaining procedures, it has been observed that the photoresist layer is in the development step or in a solution such as ammonium hydroxide (NH4OH) (1 〇% in water) in the cleaning solution infiltration process from the wafer surface peeled. This hydroxide solution is usually used to clean wafer surfaces before subsequent processing steps such as engraving or deposition. Recently, several attempts have been made regarding pre-treatment options in efforts to modify the surface to promote photoresist adhesion. These options include: dehydration, wire, and 96439.doc 200525794 applications of deep ultraviolet (DUV) anti-reflective coatings for film interlayers, standard HMDS strip primes and vapor prime based Application of organic coupling agents. However, none of these methods can sufficiently improve adhesion. Mully is the industry standard method for preparing silicon wafers for photoresist coating. The method is to use hexamethyldisilazane (HMDS) to vaporly prime the wafer surface. However, in the same way, HME) S is only chemically compatible with silicon and its oxides and does not react with most other materials. On the silicon surface, HMDS is self-gas coated with an organic monolayer that is water-repellent or resistant to other aqueous solutions such as developer or NH4OH. The water repellency of the film on the substrate / photoresist interface maintains sufficient surface energy to allow the photoresist to stick and form a film, but it prevents the photoresist film from coming off during subsequent water treatment (such as development or cleaning). It is known that the contact angle of water on a surface is a good measure of the surface energy and water repellency of the surface. The contact angle of water droplets on a silicon surface with a suitable HMDS primer is usually measured between 65-72. In addition, it has been found that the conventional vapor primer coating lasts only three days until the wafer must be primed again. In addition, in a steam-priming process, the wafer is usually brought to a temperature of 150: 1 for more than 30 minutes. This is not suitable for some temperature sensitive applications, and as mentioned earlier, the use of HMDs vapor primers has no effect on most low surface energy materials such as Teflon or other fluoropolymers. ϋ As mentioned previously, there are other ways to promote the adhesion of organic materials to the wafer surface, and more specifically to the surface of low surface energy materials. One of these methods-a method often used to modify the surface that is slow on the primer on vapor is to apply a second material such as silicon nitride (SiN) or silicon dioxide (Si) to the surface using chemical gas deposition (CVD). 〇)) 's thin layer (< 500A). This material was deposited at 96439.doc 200525794 and the conventional HMDS vaporization (coupling of the top primer provides excellent adhesion of the photoresist layer to the wafer surface. However, this' k layer, which causes additional problems, must then be removed By way of example, it has been found that the removal of materials with dry-type engraving techniques is generally very aggressive and can cause the destruction of fragile wafer layers. Other methods exist to promote photoresistance to wafers Adhesion, such as using oxygen electropolymerization to roughen the surface and add oxygen to the surface before coating the surface with a photoresist. Although this method increases the surface energy in I, a due to the intramolecular ^ ^ Φ ^ t ^ ^ ^ ® (low surface energy functional groups) restored its original low-energy water + when re-moved to the surface, which only produced-a short-lived effect [in addition, 'surface roughness remains not to a degree. In the use of amorphous In the case of Teflon Na, the oxygen system makes the surface of the breasts coarser and promotes adhesion enhancement, but allows photoresist solvents to adhere to Tefion AF®. In addition, it has been proposed to use interfacial activity mixed with photoresist materials Agent to help wet the surface. The method is complicated and the double-layer photoresist coating is required because the wetting by the first coating is usually still incomplete. Generally, 10-15% of the surfactant is required relative to the photoresist 'but the first coating is still used Only 80% of the coverage is produced. Finally, other materials have been used as interfacial adhesion promoters. The focus has been on 'and the use of photoresist developers has been described' to limit the resolution. An object of the invention is to provide a device such as a semiconductor device, a photonic device, a microfluidic device, an acoustic wave device, a stencil, or the like, which includes a material that promotes photoresistance to a low surface energy. 96439.doc 200525794 The enhanced adhesion or low-surface energy material of the adhesive to the enhanced interface material of a substrate. Another object of the present invention is to provide a device that includes a surface material that promotes enhanced adhesion The removal of the barrier layer and the surface layer after 4 does not damage the surface of the material below. Another object of the present invention is to provide a device including-promoting enhanced adhesion and allowing- The interface material of the photoresist layer of the low surface energy layer is coupled by using the method of Xiao Yixian. The other object of the present invention is to provide a method for manufacturing a device, which includes the following steps: providing a method for promoting photoresistance to a low level. Enhanced adhesion of surface energy material or enhanced adhesion interface material of low surface energy material to a substrate. [Summary of the Invention] These and other needs have been generally met by providing a device and a method of manufacturing the device, the The device includes a substrate, a low-surface energy material layer, and an amorphous carbon layer deposited on the substrate and adjacent to the low-surface energy material layer. A method of manufacturing the device includes the following steps: providing a substrate having a surface, A low surface energy material layer is deposited on the substrate, and an amorphous carbon layer is deposited on the substrate surface but adjacent to the low surface energy material layer. The amorphous carbon layer is formed using standard plasma enhanced chemical gas deposition technology (PECvD) or by money deposits. [Embodiment] In this description, according to different drawings illustrating the present invention, similar numbers are used to mark similar elements. In addition, a semiconductor device was described in the description of the preferred embodiment, but the disclosure still foresees the term, device, 96439.doc 200525794 dagger device, photonic device, microfluidic device, acoustic wave Device, embossed fork, or the like. Therefore, Fig. 1 illustrates, in a simplified sectional view, a first step of a method of manufacturing a device (i.e., a semiconductor device) according to the present invention. Illustrated in Figure 1 is a semiconductor device, generally referred to 10, which includes the provision of a substrate 12 as a first step. In this particular embodiment, the substrate 12 is described as being formed of a Shi Xi or silicon dioxide material. More specifically, the substrate 12 is described as being formed of Shi Xi. It should be understood from this that it is foreseen that the substrate 12 is made of a Group VIII material. It includes materials such as GaAs, InGaAs, InA1 As, or any similar material, or any other materials commonly used as semiconductor substrates, but not limited to silicon and stone-containing materials. Materials, certain metals and metal oxides. The substrate 12 has deposited a low surface energy material layer 14 on the upper surface 13. The low surface energy material layer 14 is typically formed of Teflon AF®, but is also disclosed as an alternative to amorphous or semi-crystalline fluoropolymers, parylene, polysiloxane-based materials such as D0w diphenylfluorene cyclobutene BCB), which includes a polysiloxane component (polydimethylsiloxane) into its structure) or the like. In this particular embodiment, the low surface energy material layer 14 is provided on the surface Η of the substrate 12 to provide the surface 13 with inherent characteristics unique to the low surface energy material, such as water repellency, inertness, low adhesion / high releasability ( low stick / high releasability), high resistance, and to protect the surface 12 from abrasion, contamination, or other foreign matter issues. It has been found that the low surface energy material layer 14 is generally difficult to wet, and as a result, nothing is stuck or coated thereon. This prevents the use of low surface energy materials in many potentially beneficial situations, such as low dielectric (10w_k) materials, non-stick photomask coatings, MEMS devices, microfluidics, for step flash compression Photolithography 96439.doc -10- 200525794 (SFIL) technology patterned layer or similar. To increase wettability and adhesion, an amorphous carbon layer 16 is deposited on the uppermost surface 15 of the low surface energy material layer 14. It has been revealed that the amorphous carbon layer 16 is formed of an amorphous carbon material deposited on the surface 15 of the low surface energy material layer 14 using a typical semiconductor deposition technique. More specifically, the amorphous carbon layer 16 is deposited on the surface 15 of the low-surface energy material layer µ using plasma enhanced chemical gas deposition (PECVD) or gold deposits. It should be understood that when plasma enhanced chemical gas deposition (pECVD) is used to deposit the amorphous carbon layer 16, it may contain other elements such as hydrogen, nitrogen, or oxygen. The amorphous carbon layer 16 provides enhanced adhesion between the substrate 12 and a photoresist (currently discussed). The carbon layer 16 is disclosed as being formed of a thin layer of amorphous carbon. In this preferred embodiment, the amorphous carbon layer 16 is deposited using standard PECvD technology well known in the industry or by sputtering to a thickness of less than 100 A and preferably 30 to 70 a. The deposition of this amorphous carbon layer 16 results in an improved adhesion durability of the subsequently deposited photoresist to the low surface energy material layer 14, which allows the low surface energy material 14 to be treated using conventional photoresist and etch-in processing techniques. See Figures 2 and 3 in the tea. Next, the wafers are stacked (generally labeled 丨 0) Ί organic photoresist stack 20. The organic photoresist stack 20 may be composed of one or more organic photoresist layers, which organic photoresist layers include materials that are sensitive to light and / or electron beams. As shown in FIG. 2, the organic photoresist stack “= becomes a standard single-layer photoresist, including the photoresist layer 22. As shown in FIG. 3, an organic photoresist stack 20 is formed as a multilayer photoresist, such as a standard double layer = Resistance, including photoresist layers 22 and 24. It should be understood that depending on the desired pattern, "form a photoresist stack 20 to include a positive photoresistor or -negative photoresist, and form a single photoresist stack with the shape 96439.doc 200525794 Or multilayer photoresist stacking has nothing to do. Do not "connect" the wafer stack 10 (more specifically, the photoresist stack 20) using a standard H method such as electron beam, light or the like, and then use it-suitable wet chemistry The developer does not show the image, and during the development process, the area% of the stack 20 is removed to form a pattern. Then, the fully developed wafer stack is etched in an oxygen plasma for a minute, and, ′, is exposed in the patterning step and is part of the non-Japanese reverse layer 16 provided by the subsequent etching step. Next, the stack_minute is etched in oxygen to remove a portion of the low surface energy material layer 14. Next, if necessary, wet the pile $ 10 times in a 10% iNH4OH solution, usually for a knife buckle. Prior to the subsequent steps (ie, etching, metallization or the like), wetting of the stack 10 in a NH4OH solution is provided to clean the exposed surface 13 of the substrate 12 for measuring adhesive strength and durability. The standard is a 10 minute soak in 1 + 0% ammonium hydroxide (NH4OH) aqueous solution at room temperature. In this infiltrated cell, the photoresist feature should not have any even minimal lift-offs or undercuts, usually smaller than submicron. The amorphous carbon layer 16 is typically deposited for about 15 seconds and it is easily removed by a low or zero bias oxygen plasma. As shown in FIG. 6, following the next desired step, the organic photoresist stack 20 and the amorphous carbon layer 16 are removed. This removal step can be performed by techniques including wet chemical dissolution or oxygen plasma ashing, or a combination thereof. As disclosed herein, a sample of a wafer patterned using a stone reverse layer and a single or double photoresist stack was developed for one minute and immersed in a 10% ammonium hydroxide solution for 10 minutes. A detailed examination of the patterned photoresist using a scanning electron 96439.doc -12- 200525794 sub-microscope (SEM) revealed that the photoresist was inseparable and its outline did not show any signs of delamination or undercutting. As a result, it was concluded that the inclusion of the amorphous carbon layer 16 produced the surface 15 of the low-surface energy material layer 14 which was very suitable for the organic photoresist stack 20 adhesion. This reveals that it is foreseen that the carbon layer 16 is formed of amorphous carbon deposited on the surface 15 of the low surface energy material layer 14 with a thickness of less than 200 a, but it should be understood that the layer 16 may have a range of 30a to 10%. , 〇〇〇a thickness. In the preferred embodiment, the carbon layer 16 is formed at a thickness between 30-70A. Two types of amorphous carbon suitable for use in making the carbon layer 16 are disclosed. More specifically, a carbon material (PLC) for a kind of polymer of the carbon layer 16 and a diamond-like carbon material (DLC) are disclosed. In a preferred embodiment, the polymer-like carbon material is described as being ~ 60% polymerized, containing an assessable amount of hydrogen, having a low density value of ~ 0.9 g / cc, and ~ 2.0 Gpa. Hardness value and optical constant data of 11 ~ ι · 7 and k 0 · 02 at 633 11111. Diamond-like carbon materials are described as ~ aggregated, containing appreciable amounts of other elements, such as nitrogen and hydrogen and may even contain oxygen, with a higher density value of ~ 0.9 g / cc, hardness of ~ 8.0 Gpa Value and optically constant data of η ~ 1.9 and k ~ 0.20 at 633 nm. Although specific carbon films that fall between the PLC and DLC specifications have not been tested, it is best to make them operate equally in this application. By changing the surface energy of the low surface energy material layer 14, the amorphous carbon layer 16 provides enhanced adhesion of the photoresist stack 20 to the surface 15 of the low surface energy material layer 14, making it possible to provide more Strong compatibility and at the same time repellent water or aqueous mixture. In an alternative embodiment, as shown in FIGS. 7 and 8, an amorphous carbon layer 16 is formed on the uppermost surface of the substrate 12, and a lower 96439.doc -13- is formed on the uppermost surface of the amorphous carbon layer 16. 200525794 Surface Energy Material Layer 14.

In order to promote the adhesion of the low surface energy material 14 'to the substrate 12, an amorphous carbon layer 16 is deposited on and adjacent to the substrate 12 before the low surface energy material 14 is deposited. This type of application should be beneficial for patterned layers of low dielectric materials, non-stick photomask coatings, MEMS devices, microfluidics, and SFIL devices. As shown in FIGS. 7 and 8, a substrate 12 is provided and formed using materials similar to those disclosed for the substrate 12 in FIG. Next, an amorphous carbon layer 16 is deposited on the substrate 12 'and adjacent to the uppermost surface 13 of the substrate 12. The amorphous carbon layer i6 is not formed of a material similar to that disclosed for the amorphous carbon layer 16 in Figs. 1-6, and it provides an enhancement of the low surface energy material 14, on the substrate 12, Sticky. The low surface energy material layer 14 is formed of Teflon AF® in this particular embodiment, but it is foreseen that it may be formed of other low surface energy material layers as described with respect to FIGS.
