Sputtering is a proven technology capable of depositing thin films from a wide variety of materials on to diverse substrate shapes and sizes. The process is repeatable and can be scaled up from small research and development projects, to production batches involving medium to large substrate areas. Read More »

Bi2O3 is used in solid-oxide fuel cells (SOFCs) as well as a raw material is making optical materials. Interest has centered on δ- Bi2O3 as it is principally an ionic conductor. In addition to electrical properties, thermal expansion properties are very important when considering possible applicati Read More »

1). SemiconductorEven though other conductors are employed in more particular applications, silicon is the best and the most used semiconductor due to its extreme mobility both at high temperatures and at room temperature. What makes Silicon an outstanding option in electronic devices is because its Read More »

Aluminum hydroxide is a common compound of aluminum, hydrogen, and oxygen that can be considered either a base, with the formula Al(OH)3, or an acid, with the formula H3 AlO3. The compound is frequently treated as a hydrate—a water-bonded compound—of aluminum oxide and designated variously as hydrat Read More »

Before a semiconductor can be built, silicon must turn into a wafer. This begins with the growth of a silicon ingot. Growing a silicon ingot can take anywhere from one week to one month, depending on many factors, including size, quality, and the specification. Let’s take a deeper look at silicon wa Read More »
