摘要:
A microelectronic topography includes a dielectric layer (DL) with a surface higher than an adjacent bulk metal feature (BMF) and further includes a barrier layer (BL) upon the BMF and extending higher than the DL. Another microelectronic topography includes a BL with a metal-oxide layer having a metal element concentration which is disproportionate relative to concentrations of the element within metal alloy layers on either side of the metal-oxide layer. A method includes forming a BL upon a BMF such that portions of a first DL adjacent to the BMF are exposed, selectively depositing a second DL upon the BL, cleaning the topography thereafter, and blanket depositing a third DL upon the cleaned topography. Another method includes polishing a microelectronic topography such that a metallization layer is coplanar with a DL and further includes spraying a deionized water based fluid upon the polished topography to remove debris from the DL.

An apparatus for processing microelectronic topographies, a method of use of such an apparatus, and a method for passivating hardware of microelectronic processing chambers are provided. The apparatus includes a substrate holder configured to support a microelectronic topography and a rotatable case with sidewalls arranged on opposing sides of the substrate holder. The method of using such an apparatus includes positioning a microelectronic topography upon a substrate holder of a processing chamber, exposing the microelectronic topography to a fluid within the processing chamber, and rotating a case of the processing chamber. The rotation is sufficient to affect movement of the fluid relative to the surface of the microelectronic topography. A method for passivating hardware of a microelectronic processing chamber includes exposing the hardware to an organic compound and subsequently exposing the hardware to an agent configured to form polar bonds with the organic compound.
摘要:
The method of the invention comprises accumulating experimental data or obtaining existing data with regard to the optimal time-temperature relationship of the deposition process on various film-formation stages for various materials, forming nuclei of a selected material on the surface of the treated object in the first stage under first temperature-controlled conditions for the formation of nuclei of said selected material, converting the nuclei of the aforementioned selected material into island-structured deposited layer of said material by causing lateral growth of the nuclei under second temperature-controlled conditions; converting the island-structure layer into a continuously interconnected cluster structure by causing further lateral growth of said island-structured deposited layer under third temperature-controlled conditions; forming a first continuous film of said material under fourth temperature controlled conditions which provides said first continuous film with predetermined properties; and then completing the formation of a final coating film by growing at least one subsequent continuous film of said material under fifth temperature-controlled conditions until a film of a predetermined thickness is obtained. The fifth temperature-controlled conditions may be characterized by a pulse-mode or step-like variations of temperature in time with rapid cooling or heating for obtaining high degree of crystallinity or for increase in the rate of deposition. The method of the invention could be realized with the use of the electroless deposition apparatus with instantaneous cooling or heating of the object, e.g., a semiconductor substrate, in a deposition chamber.
摘要:
A universal substrate holder of the invention for treating wafer substrates in liquids is provided with a shaft and a rod slidingly inserted into the central opening of the shaft. The end of the shaft that protrudes into the bowl supports a base platform for the substrate, while the end of the rod that protrudes into the bowl has radial arms that rigidly support an annular plate with pins that can pass through the opening of the base platform so that they can support the substrate above the surface of the platform. The annular plate supports clamping jaws made in the form of two-arm levers with shorter arms and longer arms. The longer arms are heavier and therefore in the stationary state of the holder keep the jaws turned into an open position. When the shaft begins to rotate, the jaws are turned under the effect of centrifugal forces into positions of clamping the substrate with the shorter arms. When the rod is pulled down, the ends of the longer arms come into contact with the base platform and are turned into the clamping position. The substrate holder of the invention allows clamping and releasing of the substrate in positions of the substrate above the platform and in a position of the substrate on the base substrate, when the backside of the substrate is inaccessible to the process liquid.
摘要:
A substrate holder has a disk-like body with a central recess having diameter smaller than the diameter of the substrate placed onto the upper surface of the holder. The substrate can be clamped in place by the clamps of the edge-grip mechanism or placed into a seat without the use of clamps. In both cases, the substrate forms a partial wall that confines the heating/cooling recess or chamber. The aforementioned recess is filled with a cooling or heating liquid (depending on the mode of metal deposition) selectively supplied from a liquid heating or cooling system. In order to ensure in the working chamber above the substrate a pressure slightly higher than the pressure in the cooling/heating recess, the working chamber is first filled with the working solution under the atmospheric pressure, and then the recess is filled with a heating or cooling liquid with simultaneous increase of pressure in the working chamber to a level slightly exceeding the pressure in the recess. The substrate holder of the invention provides direct heat/cool-exchange between the heating/cooling medium and the substrate and allows instantaneous change of temperature of the heating/cooling liquid.
摘要:
An apparatus is provided having a closable chamber that can be sealed and is capable of withstanding an increased pressure and high temperature. The chamber has several inlet ports for the supply of various process liquids, such as deposition solutions, DI water for rinsing, etc., and a port for the supply of a gas under pressure. The apparatus also includes a solution heater and a control system for controlling temperature and pressure in the chamber. Uniform deposition is achieved by carrying out the deposition process under pressure and under temperature slightly below the boiling point of the solution. The solution can be supplied from above via a shower head formed in the cover, or through the bottom of the chamber. Rinsing or other auxiliary solutions are supplied via a radially moveable chemical dispensing arm that can be arranged above the substrate parallel thereto.
摘要:
A method is provided which includes forming a metal layer and converting at least a portion of the metal layer to a hydrated metal oxide layer. Another method is provided which includes selectively depositing a dielectric layer upon another dielectric layer and selectively depositing a metal layer adjacent to the dielectric layer. Consequently, a microelectronic topography is formed which includes a metal feature and an adjacent dielectric portion comprising lower and upper layers of hydrophilic and hydrophobic material, respectively. A topography including a metal feature having a single layer with at least four elements lining a lower surface and sidewalls of the metal feature is also provided herein. The fluid/s used to form such a single layer may be analyzed by test equipment configured to measure the concentration of all four elements. In some cases, the composition of the fluid/s may be adjusted based upon the analysis.

摘要:
Methods and systems are provided which are adapted to process a microelectronic topography, particularly in association with an electroless deposition process. In general, the methods may include loading the topography into a chamber, closing the chamber to form an enclosed area, and supplying fluids to the enclosed area. In some embodiments, the fluids may fill the enclosed area. In addition or alternatively, a second enclosed area may be formed about the topography. As such, the provided system may be adapted to form different enclosed areas about a substrate holder. In some cases, the method may include agitating a solution to minimize the accumulation of bubbles upon a wafer during an electroless deposition process. As such, the system provided herein may include a means for agitating a solution in some embodiments. Such a means for agitation may be distinct from the inlet/s used to supply the solution to the chamber.
