Introduction of Zirconia Ceramics

Introduction of Zirconia Ceramics Zirconia ceramic is white, yellow or gray when it contains impurities, generally contains HfO2, and is not easy to separate. There are three crystalline states of pure ZrO2 under normal pressure. The production of zirconia ceramics requires the preparation of powders with high purity, good dispersion properties, ultra-fine particles and narrow particle size distribution. There are many preparation methods for zirconia ultra-fine powder. The purification of zirconia mainly includes chlorination and thermal decomposition, alkali metal oxidative decomposition method, [...]

What is Piezoelectric Ceramics

What is Piezoelectric Ceramics Piezoelectric ceramics refer to polycrystals formed by mixing oxides (zirconia, lead oxide, titanium oxide, etc.) after high-temperature sintering and solid-phase reaction, and making them have piezoelectric effect through DC high-voltage polarization treatment. A general term for ferroelectric ceramics, it is a functional ceramic material that can convert mechanical energy and electrical energy into each other. Piezoelectric ceramics are a class of electronic ceramic materials with piezoelectric properties. The main difference from typical piezoelectric quartz crystals that do [...]

What is sapphire

What is sapphire Sapphire is a precious gemstone, a variety of the mineral corundum, consisting of aluminium oxide (α-Al2O3) with trace amounts of elements such as iron, titanium, chromium, vanadium, or magnesium.The name sapphire is derived from the Latin “saphirus” and the Greek “sapheiros”, both of which mean blue. It is typically blue, but natural “fancy” sapphires also occur in yellow, purple, orange, and green colors; “parti sapphires” show two or more colors. Red corundum stones also occur, but are called [...]

A simple understanding of semiconductor silicon wafers

A simple understanding of semiconductor silicon wafers      一， Introduction to Semiconductor Wafers The research of semiconductor originated from the research of solid state physics and electronic science. In 1938, Shaw’s paper “Rectification at the Metal-Semiconductor Interface” was the first to link the fundamental research of solid state physics with the performance of semiconductor components. At the end of 1947, the first transistor was born at Bell Labs. Early research on solid-state physics was based on germanium crystals as transistors, but [...]

Processing flow of single crystal silicon ingots in the semiconductor industry

Processing flow of single crystal silicon ingots in the semiconductor industry In the single-crystal silicon wafer preparation stage, the silicon single-crystal ingots need to be processed into raw silicon wafers or barewa-fers with high surface accuracy and surface quality to prepare for planarization for lithography and other processes in the first half of the IC process. Ultra-smooth and damage-free substrate surface are required here. For silicon wafers with a diameter of ≤200mm, the traditional silicon wafer processing process is: single crystal growth → [...]
