LASER INDUCED FORWARD TRANSFER OF 2D MATERIALS
A system and method for performing is laser induced forward transfer (LIFT) of 2D materials is disclosed. The method includes generating a receiver substrate, generating a donor substrate, wherein the donor substrate comprises a back surface and a front surface, applying a coating to the front surface, wherein the coating includes donor material, aligning the front surface of the donor substrate to be parallel to and facing the receiver substrate, wherein the donor material is disposed adjacent to the target layer, and irradiating the coating through the back surface of the donor substrate with one or more laser pulses produced by a laser to transfer a portion of the donor material to the target layer. The donor material may include Bi.sub.2S.sub.3-xS.sub.x, MoS.sub.2, hexagonal boron nitride (h-BN) or graphene. The method may be used to create touch sensors and other electronic components.
Method of site-specific deposition onto a free-standing carbon article
The system and method includes the suspension of a free-standing carbon article within a reaction chamber, the introduction of the chemical precursor in a reaction environment within the chamber, and heating of the carbon article in the presence of the chemical precursor leading to deposition in a site-specific manner.

A thin film laminate comprises a metal layer consisting of a metal, and a thin film laminated on the surface of the metal layer, wherein a first direction is defined as one direction parallel to the surface of the metal layer, and a second direction is defined as one direction parallel to the surface of the metal layer and crossing the first direction; and the metal layer contains a plurality of first metal grains consisting of the metal and extending in the first direction on the surface of the metal layer, and a plurality of second metal grains consisting of the metal and extending in the second direction on the surface of the metal layer.
Solid precursor feed system for thin film depositions
A dry powder MOCVD vapor source system is disclosed that utilizes a gravimetric powder feeder, a feed rate measurement and feeder control system, an evaporator and a load lock system for continuous operation for thin film production, particularly of REBCO type high temperature superconductor (HTS) tapes.
Heat treatment method including low temperature degassing before flash lamp anneal and heat treatment apparatus thereof
A semiconductor wafer to be treated is heated at a first preheating temperature ranging from 100 to 200° C. while a pressure in a chamber housing the semiconductor wafer is reduced to a pressure lower than an atmospheric pressure. After the semiconductor wafer is preheated to increase the temperature into a second preheating temperature ranging from 500 to 700° C. while the pressure in the chamber is restored to a pressure higher than the reduced pressure, a flash lamp emits a flashlight to a surface of the semiconductor wafer. Heating the semiconductor wafer at the first preheating temperature that is a relatively low temperature enables, for example, the moisture absorbed on the surface of the semiconductor wafer in trace amounts to be desorbed from the surface, and also enables the flash heating treatment to be performed with oxygen derived from such absorption removed as much as possible.
