Title:
ALUMINUM NITRIDE-BASED SINTERED COMPACT AND SEMICONDUCTOR HOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/221504
Kind Code:
A1
Abstract:
An aluminum nitride-based sintered compact 1 includes: crystalline particles 2 of Mg-containing aluminum nitride; a composite oxide which has a Garnet type crystal structure and contains a rare earth element and Al; and a composite oxynitride that contains Mg and Al. Particles 3 of the composite oxide and particles 4 of the composite oxynitride are scattered between the crystalline particles 2 of the Mg-containing aluminum nitride. The composite oxide may contain Y. The crystalline particles 2 of the Mg-containing aluminum nitride may contain 0.1-1.0 mol% of Mg if the content of all contained metal elements is taken to be 100 mol%. A semiconductor holding device is provided with this aluminum nitride-based sintered compact 1 and an electrode 13 for electrostatic adsorption.
