"A new microelectronics technique called Solid Logic Technology, or SLT, is utilized in the new family of IBM/360 computers. This new technology provides a hybrid, integrated circuit module which combines discrete, glass-encapsulated silicon transistors and diodes with stencil-screened land patterns and precision passive components."
