Wafer Manufacturing

Ink marking is a key process for die sorting of IC wafer manufacturing. Intensive production of wafer is urging the inkers for more rapid and more stable ink marking performance on surface of defective wafer dies safely. In this paper, a non-contact jetting dispenser is introduced to the wafer die marking. After presenting the mathematical description of dynamic fluid for 2-phase flow, numerical simulations are launched to reveal the characteristics of droplet generation and key factors are discussed. A jetting dispenser is developed and experimental results are analyzed. According to the simulative results and the dotting performance shown in experiments, the non-contact jetting dispenser is capable for wafer die marking in dotting efficiency and stability.

The study focuses on the dynamic model of the three-linear spool flow regulator for various solutions of the spool geometry, and for two variants of mathematical description of hydraulic damping devices. The paper describes the process of small deflection linearization of the obtained mathematical models. As a result of Laplace transformation of the mathematical models, we obtained a block diagram of the spool flow regulator operation. By using Nyquist criterion, we analyzed the spool flow regulator stability. As a result, we draw conclusions on the spool flow regulator stability, and on the various types of damping devices affecting it

Solution Conductivity

A dynamic model of an underwater electric discharge is presented. The method is based on a mathematical description of the dependence of the solution conductivity on its thickness during the formation of a vapor-gas bubble. The time dependences of the current and the voltage drop across the cell were calculated using expressions relating the current and voltage to the resistance (conductivity) of the solution and taking into account the periodicity of the processes. The presented model makes it possible to accurately describe the dynamic characteristics of underwater discharges based on the physicochemical properties of the solution, which makes it possible to predict the behavior of the discharge when using solutions with specified properties.
