    摘要: Embodiments disclosed include methods of processing substrates, including methods of forming conductive connections to substrates. In one embodiment, a method of processing a substrate includes forming a material to be etched over a first material of a substrate. The material to be etched and the first material are of different compositions. The material to be etched is etched in a dry etch chamber to expose the first material. After the etching, the first material is contacted with a non-oxygen-containing gas in situ within the dry etch chamber effective to form a second material physically contacting onto the first material. The second material comprises a component of the first material and a component of the gas. In one embodiment, the first material is contacted with a gas that may or may not include oxygen in situ within the dry etch chamber effective to form a conductive second material.

    摘要: A method for manufacturing surgical blades from either a crystalline or poly-crystalline material, preferably in the form of a wafer, is disclosed. The method includes preparing the crystalline or poly-crystalline wafers by mounting them and machining trenches into the wafers. The methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw, laser system, ultrasonic machine, and a hot forge press. The wafers are then placed in an etchant solution which isotropically etches the wafers in a uniform manner, such that layers of crystalline or poly-crystalline material are removed uniformly, producing single or double bevel blades. Nearly any angle can be machined into the wafer which remains after etching. The resulting radii of the blade edges is 5-500 nm, which is the same caliber as a diamond edged blade, but manufactured at a fraction of the cost.

    摘要: A plasma processing method for processing a target substrate uses a plasma processing apparatus which includes a vacuum evacuable processing vessel for accommodating the target substrate therein, a first electrode disposed in the processing vessel and connected to a first RF power supply for plasma generation and a second electrode disposed to face the first electrode. The method includes exciting a processing gas containing fluorocarbon in the processing vessel to generate a plasma while applying a negative DC voltage having an absolute value ranging from about 100 V to 1500 V or an RF power of a frequency lower than about 4 MHz to the second electrode. The target layer is etched by the plasma, thus forming recesses on the etching target layer based on the pattern of the resist layer.

    摘要: Etching of nitride and oxide layers with reactant gases is modulated by etching in different process regimes. High etch selectivity to silicon nitride is achieved in an adsorption regime where the partial pressure of the etchant is lower than its vapor pressure. Low etch selectivity to silicon nitride is achieved in a condensation regime where the partial pressure of the etchant is higher than its vapor pressure. By controlling partial pressure of the etchant, very high etch selectivity to silicon nitride may be achieved.

    摘要: A method for making a chrome photo-mask is disclosed. A photo-mask blank is activated with activator on its upper surface for electroless chrome plating Next, the activated photo-mask blank is then immersed in the electroless chrome plating solution for being coated with a thin chrome layer. The electroless chrome plating process will continue until a desired thickness is formed. Preferably, an electro-plating process is employed after the growth of an initial electroless chrome layer. Then, the photo-mask blank with the chrome layer is subject to oxidation for forming an antireflection layer on the chrome layer. After the antireflective layer is successively formed, a resist film is formed on the antireflective layer. The resist film is then patterned in accordance with the predetermined pattern. Next, the antireflective layer and the chromium layer are dry-etched or wet-etched through openings in the patterned resist film. The resist film is subsequently stripped to form the desired photo-mask.
