Control in Semiconductor Wafer Manufacturing

Control of pressure, temperature, and flow is ubiquitous. Robotics (wafer handling) is omnipresent in the fab. The semiconductor manufacturing process flow, when highly simplified, can be divided into two primary cycles of transistor and interconnect fabrication. The transistor cycle is the basis of the most advanced chips, see Figure 2. With

Semiconductor fabrication analysis

Wafer Cleaning A recurrent step in the fabrication of an integrated circuit is to clean and prepare the silicon wafer for a subsequent process step. Complete cleaning of semiconductor surfaces requires that particulates, organic films, and adsorbed metal ions be removed. Most cleaning procedures are based on immersion in liquid baths

The Process of Die Preparation in Wafer Manufacturing

Wafer mounting is the process of mounting a wafer on a plastic tape that is connected to a ring. This step aims to provide support to assist the processing of the wafer from wafer sawing to die to attach. Wafer mounting is done before the wafers are cut into individual dies. During wafer mounting, the wafer frame and the wafer are attached to a ...

CMOS Fabrication : Process Steps And Twin tub Process

In early 1960’s the semiconductor manufacturing process was initiated from Texas and in 1963 CMOS or complementary metal oxide semiconductor was patented by Frank Wanlass. Integrated circuits are manufactured by utilizing the semiconductor device fabrication process. These ICs are major components of every electrical and electronic devices which we use in our daily life.
