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.

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.
摘要翻译：用于处理液体中的晶片基板的本发明的通用基板保持器设置有滑动地插入轴的中心开口中的轴和杆。突出到碗中的轴的端部支撑用于基底的基座，而突出到碗中的杆的端部具有径向臂，其刚性地支撑环形板，销可以穿过基座的开口使得它们可以支撑平台表面上方的基板。环形板支撑以双臂杠杆的形式制成的夹爪，其具有较短的臂和较长的臂。较长的手臂较重，因此在保持架的静止状态下，保持夹爪变为打开位置。当轴开始旋转时，夹爪在离心力的作用下转动到用较短的臂夹持基板的位置。当杆被拉下时，较长臂的端部与基座平台接触并转动到夹紧位置。本发明的衬底保持器允许当衬底的背面不可用于处理液体时，衬底在平台上方的位置和衬底在基底衬底上的位置的夹持和释放。

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： 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.
