  • Publication number: 20240136175
    Abstract: The present invention relates to an auxiliary precursor, a thin film precursor composition, a method of forming a thin film using the thin film precursor composition, and a semiconductor substrate fabricated using the method. The present invention provides the thin film precursor composition including a thin film precursor compound and a compound having a predetermined structure that exhibits reaction stability as the auxiliary precursor. By using the thin film precursor composition in a thin film deposition process, side reactions may be suppressed, and thin film growth rate may be appropriately controlled. In addition, since process by-products are removed from a thin film, even when a thin film is formed on a substrate having a complicated structure, step coverage and the thickness uniformity and resistivity characteristics of the thin film may be greatly improved.

  • Patent number: 9627201
    Abstract: In a method of forming holes, a plurality of guide patterns physically spaced apart from each other is formed on an object layer. The guide pattern has a ring shape and includes a first opening therein. A self-aligned layer is formed on the object layer and the guide patterns to fill the first opening. Preliminary holes are formed by removing portions of the self-aligned layer which are self-assembled in the first opening and between the guide patterns neighboring each other. The object layer is partially etched through the preliminary holes.

  • Patent number: 8986554
    Abstract: A method of forming patterns includes forming a photoresist film on a substrate. The photoresist film is exposed with a first dose of light to form a first area and a second area in the photoresist film. A first hole and a second hole are formed by removing the first area and the second area with a first developer. The photoresist film is re-exposed with a second dose of the light to form a third area in the photoresist film between the first hole and the second hole. A third hole is formed between the first hole and the second hole by removing the third area with a second developer.

  • Patent number: 8946089
    Abstract: Methods of forming contact holes include forming a first guide pattern over an etching target layer. The first guide pattern has first openings each extending in a first direction and each first opening arranged in a direction perpendicular to the first direction. A first BCP structure is formed in each first opening. The first BCP structure includes first material layers in the first direction at a first pitch in each of the first openings, and second material layers filling a remaining portion of each first opening. First holes are formed by removing the first material layers. A second guide pattern is formed over the first guide pattern and the second material layers, and the above processes are performed on the second guide pattern to form second holes. Portions of the etching target layer overlapped by the first holes or the second holes are removed to form a desired pattern.

  • Patent number: 8900468
    Abstract: A method includes forming a hydrophilic guide layer, a DBARC layer and a photoresist film. A portion of the photoresist film and DBARC layer is exposed to form exposed and unexposed portions. The unexposed photoresist film is removed to form a photoresist pattern including the exposed photoresist film portion. A neutral layer is formed on the photoresist pattern. The photoresist pattern and the DBARC layer of the exposed portion are removed to form first opening portions exposing the guide layer. A block copolymer layer includes a block copolymer having first and second polymer blocks coated on the neutral layer while filling the first opening portions. The block copolymer layer is microphase separated to form a pattern layer including first and second patterns. A pattern including one polymer block is removed to form a pattern mask. The object layer is etched to form a pattern including second opening portions.

  • Publication number: 20130288482
    Abstract: In a method of forming a pattern, a photoresist pattern is formed on a substrate including an etching target layer. A surface treatment is performed on the photoresist pattern to form a guide pattern having a higher heat-resistance than the photoresist pattern. A material layer including a block copolymer including at least two polymer blocks is coated on a portion of the substrate exposed by the guide pattern. A micro-phase separation is performed on the material layer to form a minute pattern layer including different polymer blocks arranged alternately. At least one polymer block is removed from the minute pattern layer to form a minute pattern mask. The etching target layer is etched by using the minute pattern mask to form a pattern. Minute patterns may be formed utilizing a less complex process that those employed during conventional processes of forming a minute pattern.

  • Patent number: 6466042
    Abstract: A wafer probe card for a probing test of an integrated circuit chip on a silicon wafer is disclosed. As the wafer probe card is made of a silicon wafer and manufactured by a general wafer fabrication process, the wafer probe card having a desired silicon micro tip has the same physical characteristics as that of the silicon IC chip. Accordingly, when probing test of a semiconductor IC chip by connecting the silicon micro tip to a pad, all the chips on the wafer can be tested at the same time to thereby simplify and automate the process of the probing test.

  • Patent number: 5876509
    Abstract: A cleaning solution of a semiconductor device is composed of aqueous ammonia (NH.sub.4 OH), methanol (CH.sub.3 OH), hydrofluoric acid (HF) and deionized water (DI--H.sub.2 O), the volume ratio of NH.sub.4 OH to CH.sub.3 OH to DI--H.sub.2 O being 1:1-50:0.1-50, and the volume of HF being 1-10,000 ppm with respect to the mixture solution of NH.sub.4 OH, CH.sub.3 OH and DI--H.sub.2 O. The cleaning solution can be manufactured by simply mixing the respective compositions. The cleaning solution can strip polymers and particles within a short time, without etching or damaging the cleaned metal layers. Since the cleaning process of a semiconductor device is simplified, the processing cost is reduced and the yield and reliability are improved.
