1. Molding Technology for Ultra-Thin Ceramic Sheets Our company employs a doctor blade method for the coating process of green sheets. We mix carefully selected ceramic raw materials and resin materials, and by molding sheets using the doctor blade method, we produce green sheets with stable thickness and strength. With high-precision gap management of the blade, we are able to achieve green sheets as thin as 20 micrometers. (We are also developing coating technology for layers as thin as 5 micrometers.)

basic information

Ultra-thin zirconia ceramics substrate technology This is a sample of an ultra-thin substrate with a thickness of 50 µm made from zirconia ceramics. Due to its ultra-thinness (50 µm), the underlying layer is visible. Because of the high toughness of the zirconia material, it is possible to "bend" even though it is a ceramics substrate.
