Patent number: 8906452Abstract: An improved technique achieves a uniform photoresist film on a wafer by controlling the volatility of the solvent in a photoresist solution during the bake process step. Because film formation takes place in the bake rather than the spin steps of the process, the improved technique involves using less viscous and therefore less costly and easier to use resists to cast relatively thick photoresist films. Such control is achieved in an enclosed chamber into which a carrier gas is introduced; the carrier gas mixes with gaseous solvent to create a saturating atmosphere in which the rate of evaporation of solvent decreases. This enables the heating of the wafer without the reduction of solvent in the film so that the photoresist can self-level. When the film has self-leveled, the solvent is then baked off as usual.Type: GrantFiled: May 24, 2012Date of Patent: December 9, 2014Inventor: Gary Hillman

Patent number: 8603923Abstract: This invention relates to a dipping solution used in a process for producing a siliceous film. The present invention provides a dipping solution and a siliceous film-production process employing the solution. The dipping solution enables to form a homogeneous siliceous film even in concave portions of a substrate having concave portions and convex portions. The substrate is coated with a polysilazane composition, and then dipped in the solution before fire. The dipping solution comprises hydrogen peroxide, a foam-deposit inhibitor, and a solvent.Type: GrantFiled: June 18, 2013Date of Patent: December 10, 2013Inventor: Masanobu Hayashi

Patent number: 8580340Abstract: After a solvent is discharged onto a substrate in a period from a time point t0 to a time point t1, rotation of the substrate is started at a time point t2. A resist liquid is discharged onto a center portion of a target surface of the substrate at a time point t3. A rotation speed of the substrate starts to decrease at a time point t4, and attains a first speed after a certain period of time. The discharge of the resist liquid is stopped at a time point t5. The rotation of the substrate is accelerated in a period from a time point t6 to a time point t7, and the rotation speed of the substrate attains a second speed at the time point t7. The rotation of the substrate is decelerated in a period from the time point t7 to a time point t8, and the rotation speed of the substrate attains a third speed at the time point t8.Type: GrantFiled: October 6, 2010Date of Patent: November 12, 2013Assignee: Sokudo Co., Ltd.Inventors: Masanori Imamura, Akihiro Hisai, Hidetoshi Sagawa

Publication number: 20130295777Abstract: A substrate is rotated at a first rotation number (first step). The rotation of the substrate is decelerated to 1500 rpm that is a second rotation number and the substrate is rotated at the second rotation number for 0.5 seconds (second step). The rotation of the substrate is further decelerated to a third rotation number and the substrate is rotated at the third rotation number (third step). The rotation of the substrate is accelerated to a fourth rotation number and the substrate is rotated at the fourth rotation number (fourth step). A resist solution is continuously supplied to a center portion of the substrate from a middle of the first step to a middle of the third step.Type: ApplicationFiled: July 3, 2013Publication date: November 7, 2013Inventors: Katsunori ICHINO, Koji TAKAYANAGI, Tomohiro NODA

Patent number: 8574674Abstract: A substrate is first rotated at a first rotation speed, and a resist solution is applied. Rotation of the substrate is decelerated to a second rotation speed lower than the first rotation speed so that the substrate is rotated at the low speed to smooth the resist solution on the substrate. Rotation of the substrate is then accelerated to a third rotation speed higher than the second rotation speed, and a solvent for the coating solution and/or a dry gas are/is supplied to the resist solution on the substrate. The solvent gas is supplied to a portion of the resist solution on the substrate thicker than a set thickness, and the dry gas is supplied to a portion of the coating solution on the substrate thinner than the set thickness. This thins the thicker portion of the resist solution and thickens the thinner portion to uniform the resist solution.Type: GrantFiled: December 20, 2011Date of Patent: November 5, 2013Assignee: Tokyo Electron LimitedInventor: Takashi Tanaka

Publication number: 20130288485Abstract: A method of forming a dielectric layer is described. The method first deposits an initially-flowable layer on a substrate. The initially-flowable layer is then densified by exposing the substrate to a high-density plasma (HDP). Essentially no additional material is deposited on the initially-flowable layer, in embodiments, but the impact of the accelerated ionic species serves to condense the layer and increase the etch tolerance of the processed layer.Type: ApplicationFiled: March 11, 2013Publication date: October 31, 2013Applicant: Applied Materials, Inc.Inventors: Jingmei Liang, Sukwon Hong, Jun Tae Choi

Publication number: 20130260574Abstract: In a substrate processing apparatus, with an internal space of a chamber brought into a reduced pressure atmosphere, a first processing liquid is supplied onto an upper surface of a substrate while the substrate is rotated, and the first processing liquid is thereby quickly spread from a center portion toward a peripheral portion on the upper surface of the substrate. It is thereby possible to coat the upper surface of the substrate with the first processing liquid in a shorter time as compared with under normal pressure. Further, by sucking the first processing liquid from the vicinity of an edge of the substrate, it is possible to coat the upper surface of the substrate with the first processing liquid in a still shorter time. As a result, it is possible to shorten the time required for the processing of the substrate.Type: ApplicationFiled: March 28, 2013Publication date: October 3, 2013Applicant: DAINIPPON SCREEN MFG.
