Abstract:
PROBLEM TO BE SOLVED: To provide a process of atomic layer deposition (ALD) to form a silicon dioxide thin film at low temperature under various conditions. SOLUTION: In one preferred embodiment, for example, a silicon dioxide thin film is deposited on a sensitive or flexible surface, to form part of a solar cell, a magnetic head, a device of an MEMS, an ink-jet device, or another microfluidic device. In another preferred embodiment, there are deposited a shallow trench isolation (STI) structure, a sidewall spacer and a gate passivation layer. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a process and a system for baking in a low pressure impurities to remove from a semiconductor surface before deposition. SOLUTION: Low temperature treatment consumes only a part of a heat history in a short time but has advantage of effectively removing the interfacial oxygen from a semiconductor surface. The process and system are suitable especially for the treatment of a semiconductor surface before epitaxial growth. According to an embodiment, the process is provided for treating a semiconductor substrate in which the substrate is loaded on a substrate supporter in a reaction chamber by the chemical vapor deposition method, and the pressure in the reaction chamber is reduced to a baking pressure of about 1×10 -6 Torr (about 133.32×10 -6 Pa) to 10 Torr (about 1333.22 Pa).

Abstract:
PROBLEM TO BE SOLVED: To provide doping which allows the concentration and uniformity of a deposited dopant to be controlled by blocking some of the available binding sites for a dopant precursor with a blocking reactant and allows the blocking reactant to be introduced prior to introduction of the dopant precursor in an ALD (atomic layer deposition) process or allows the blocking reactant and the dopant precursor to be introduced simultaneously. SOLUTION: A method for doping a substrate surface or an interface between two thin films by the ALD process is provided. The ALD process generally comprises steps of providing a substrate to a reaction space and depositing a dopant on the substrate in a single ALD cycle, in which the substrate is contacted with a first reactant that is a blocking reactant such that the blocking reactant adsorbs in a self-limiting manner on the surface of the substrate.
