Methods of manufacturing semiconductor devices
A method of manufacturing a semiconductor device includes forming a three-dimensional (3D) structure on a substrate, forming an adsorption control layer to cover an upper portion of the 3D structure, and forming a material layer on the adsorption control layer and on a lower portion of the 3D structure that is not covered by the adsorption control layer, wherein a minimum thickness of the material layer on the adsorption control layer is less than a maximum thickness of the material layer on the lower portion of the 3D structure.
Forming III nitride alloys
A method for forming a semiconductor device involves selecting a substrate on which a wurtzite III-nitride alloy layer will be formed, and a piezoelectric polarization and an effective piezoelectric coefficient for the wurtzite III-nitride alloy layer. It is determined whether there is a wurtzite III-nitride alloy composition satisfying the selected effective piezoelectric coefficient. It is also determined whether there is a thickness for a layer formed from the wurtzite III-nitride alloy composition satisfying the selected piezoelectric polarization based on the selected substrate and the selected effective piezoelectric coefficient. Responsive to the determination that there is a wurtzite III-nitride alloy composition having a lattice constant satisfying the selected effective piezoelectric coefficient and a thickness for the layer formed from the wurtzite III-nitride alloy composition satisfying the selected piezoelectric polarization, the wurtzite III-nitride alloy layer is formed on the substrate having the wurtzite III-nitride alloy composition satisfying the selected effective piezoelectric coefficient and having the thickness satisfying the selected piezoelectric polarization.
LAMINATE FILM AND ELECTRODE SUBSTRATE FILM, AND METHOD OF MANUFACTURING THE SAME
[Object] Provided are a laminate film and an electrode substrate film with excellent etching quality, in which a circuit pattern formed by etching processing is less visible under highly bright illumination, and a method of manufacturing the same.
[Solving Means] A laminate film includes a transparent substrate 60 formed of a resin film and a layered film provided on at least one surface of the transparent substrate. The layered film includes metal absorption layers 61 and 63 as a first layer and metal layers (62, 65), (64, 66) as a second layer, counted from the transparent substrate side. The metal absorption layers are formed by a reactive sputtering method which uses a metal target made of Ni alone or an alloy containing two or more elements selected from Ni, Ti, Al, V, W, Ta, Si, Cr, Ag, Mo, and Cu, and a reactive gas containing oxygen. The reactive gas contains hydrogen.
Mechanism for FinFET well doping
The embodiments of mechanisms for doping wells of finFET devices described in this disclosure utilize depositing doped films to dope well regions. The mechanisms enable maintaining low dopant concentration in the channel regions next to the doped well regions. As a result, transistor performance can be greatly improved. The mechanisms involve depositing doped films prior to forming isolation structures for transistors. The dopants in the doped films are used to dope the well regions near fins. The isolation structures are filled with a flowable dielectric material, which is converted to silicon oxide with the usage of microwave anneal. The microwave anneal enables conversion of the flowable dielectric material to silicon oxide without causing dopant diffusion. Additional well implants may be performed to form deep wells. Microwave anneal(s) may be used to anneal defects in the substrate and fins.
