Atomic layer etching processes
Atomic layer etching (ALE) processes are disclosed. In some embodiments, the methods comprise at least one etch cycle in which the substrate is alternately and sequentially exposed to a first vapor phase non-metal halide reactant and a second vapor phase halide reactant. In some embodiments both the first and second reactants are chloride reactants. In some embodiments the first reactant is fluorinating gas and the second reactant is a chlorinating gas. In some embodiments a thermal ALE cycle is used in which the substrate is not contacted with a plasma reactant.
METHOD AND APPARATUS FOR FILLING A GAP
According to the invention there is provided a method of filling one or more gaps created during manufacturing of a feature on a substrate by providing a deposition method comprising; introducing a first reactant to the substrate with a first dose, thereby forming no more than about one monolayer by the first reactant; introducing a second reactant to the substrate with a second dose. The first reactant is introduced with a sub saturating first dose reaching only a top area of the surface of the one or more gaps and the second reactant is introduced with a saturating second dose reaching a bottom area of the surface of the one or more gaps. A third reactant may be provided to the substrate in the reaction chamber with a third dose, the third reactant reacting with at least one of the first and second reactant.

The control device includes: a holding unit that holds a table for each of the division regions; a measuring unit that measures the resistance value of each of the heaters embedded in the placing table for each of the division regions; and a controller that estimates a temperature of each of the division regions corresponding to the resistance value of each of the heaters measured by the measuring unit with reference to the table for each of the division regions, and controls an electric power to be supplied to each of the heaters so that the estimated temperature becomes a target temperature.
PATTERN TRANSFER TECHNIQUE AND METHOD OF MANUFACTURING THE SAME
A photo-free lithography process with low cost, high throughput, and high reliability is provided. A template mask is bonded to a production workpiece and comprises a plurality of openings defining a pattern. An etch is performed into the production workpiece, through the plurality of openings, to transfer the pattern of the template mask to the production workpiece. The template mask is de-bonded from the production workpiece. A system for performing the photo-free lithography process is also provided.
Circulating cooling/heating device
A circulating cooling/heating device that is configured to cool and heat a circulating fluid supplied to a chamber in plasma-etching equipment includes: a reservoir configured to store the circulating fluid; a pump configured to circulate the circulating fluid between the reservoir and the chamber; a heat exchanger configured to perform heat exchange between the circulating fluid and a cooling water, the heat exchanger being immersed in the circulating fluid stored in the reservoir; and a heater configured to heat the circulating fluid in the reservoir.
Single platform, multiple cycle spacer deposition and etch
A first portion of a multiple cycle spacer is formed on a sidewall of a patterned feature over a substrate. A spacer layer is deposited on the first portion using a first plasma process. The spacer layer is etched to form a second portion of the multiple cycle spacer on the first portion using a second plasma process. A cycle comprising depositing and etching of the spacer layer is continuously repeated until the multiple cycle spacer is formed.

A gas distribution plate assembly for a processing chamber is provided that in one embodiment includes a body made of a metallic material, a base plate comprising a silicon infiltrated metal matrix composite coupled to the body, and a perforated faceplate comprising a silicon disk coupled to the base plate by a bond layer.
Conductive film and method of making same
A method for making a conductive film includes the steps of: depositing a conductive metal film on a substrate to form a metal-coated substrate; depositing a fiber pattern on the conductive metal film of the metal-coated substrate to form a masked substrate, the fiber pattern defining protected metal and exposed metal of the conductive metal film; removing the exposed metal from the conductive metal film of the masked substrate to form a protected conductive film; and removing the fiber pattern from the protected conductive film to expose the protected metal and provide a metal pattern on the substrate. An annealing step con be employed after depositing the fiber pattern to increase the surface area of contact between the fiber pattern and the conductive metal film.
PLASMA DICING OF SILICON CARBIDE
A method of forming a semiconductor device includes forming an active region in a first side of a silicon carbide substrate, the silicon carbide substrate having a second side opposite the first side and forming a contact pad at the first side. The contact pad is coupled to the active region. The method further includes forming an etch stop layer over the contact pad and plasma dicing the silicon carbide substrate from the second side. The plasma dicing etches through the silicon carbide substrate and stops on the etch stop layer. The diced silicon carbide substrate is held together by the etch stop layer. The diced silicon carbide substrate is attached on a carrier. The diced silicon carbide substrate is separated into silicon carbide dies by cleaving the etch stop layer.
