The thickness of the wafer is an important indicator of component availability. Wafers are used in the production of integrated circuits and as substrates for microelectronic equipment. Various types of wafers have various applications, and for each application, a specific wafer diameter needs to be followed. Alfa Chemistry provides customers with accurate wafer thickness testing services to meet customer application requirements. The test items can accurately measure the thickness uniformity and tolerance of each wafer. You can rest assured of our test report.
Alfa Chemistry uses capacitive sensing technology to measure wafer thickness. The wafer is located between the two probes. The distance between the probes is accurately known, and the gap between the wafer and the probes is derived from the capacitance at each measurement point.
Alfa Chemistry uses a non-contact capacitive scanner to measure the thickness and shape of rotating wafers. Compared with laser interference, capacitive sensing technology has low cost, but good stability, high precision and resolution.
Alfa Chemistry has high-precision and advanced testing instruments, which can provide accurate test results. Our testing instruments include, but are not limited to, the following:
