A SI-CMOS-MEMS PROCESS USING BACK-SIDE GRINDING Y.-J. Fang 1, A. Wung 1, T. Mukherjee 1, and G.K. Fedder 1, 2, 3 1Department of Electrical and Comput er Engineering, Pi ttsburgh, PA, USA 2The Robotics Institute, Pittsburgh, PA, USA 3 Institute for Complex Engineered Systems, Pittsburgh, PA, USA ABSTRACT This paper presents a Si-CMOS-MEMS fabrication
The application of precision grinding for the formation of a silicon diaphragm is investigated. The test structures involved 2-6 mm diam diaphragms with thicknesses in the range of 25-150 μm. When grinding is performed without supporting the diaphragm, bending occurs due to nonuniform removal of the silicon material over the diaphragm region.
As a case study of vertical shaft spring grinder, this paper analyses the process of spring end grinding and establishes geometric model of spring face grinding, then calculates the formula of grinding force by the formula of surface grinding machine with vertical spindle and rotary table. Meanwhile, the paper also analyses the relation of grinding...

With our partners in Asia we provide the following wafer foundry services to semiconductor and MEMS industry from single process to proto-type product to high volume capacity. SOI wafer with uniformity of +/-0.5 µ by grinding and polishing; Ultra uniform SOI wafer with uniformity of +/-0.15 µ by layer transfer;
In MEMS sensors, such as pressure sensor, sensitivity of the sensor is directly related to SOI membrane thickness. High variability of thickness will result in poor device properties. Our proprietary technology allows us to produce ultra uniform SOI wafers through layer

2021-1-16 Temperature levels of 800°C -1100°C accelerate the coating process. Diffusion of oxygen into the surface can form silicon dioxide on a silicon substrate; substrate penetration improves electrical insulation. Unfortunately, coatings thicker than ~100 nanometers can generate additional surface films that restrict use for MEMS applications.

A schematic diagram of EC Grinding is shown in Fig. 5.2.39. Here, metallic wheel acts as cathode and rotates over the anodic workpiece. Both are immersed in electrolytic chamber. This process is specially utilized for producing flat surface with very good surface finish hence it requires very small gap between job and the metallic wheel.
With a 2000 grit grinding process, the stress required to break the die was 50 percent higher than the stress needed to break a die with a (larger) 1200 grit grinding process. Figure 2 shows the method of applying the test force to the die, and Figure 3 shows the difference in the scratches on the wafers using different grits to grind the silicon.
