How To Reduce Tape-out Costs? How To Reduce Tape-out Costs? Spray photoresist onto MEMS wafers - Cheersonic Taping out is expensive, on the one hand, because there are many processes that need to be verified at the beginning, from a circuit diagram to a chip, to check whether each process step is feasible and whether the circuit has the required performance and functions. The chip tape-out process lasts [...]

Chip Thin Film Deposition A chip is a 3D structure formed by stacking a series of active and passive circuit elements, and thin film deposition is one of the core processes in the front-end manufacturing of the chip. From the cross-section of the chip, the chip is composed of layers of nanoscale components. All active circuit components (such as transistors, memory cells, etc.) are concentrated at the bottom [...]

Ultrasonic Dispersion Syringe System Ultrasonic Dispersion Syringe System - Catalyst Ink Dispersion - Cheersonic We have much experience in spraying PEM. The ultrasonic coating system produce highly durable, uniform coatings of carbon-based catalyst inks onto both fuel cell and electeolysis process for PEM electrolyzers such as Nafion. And we have provide so many ultrasonic spray coating euqipments for universities, institute and some enterprise, especially the automatic equipment. According [...]

Important Instruments In Chip Manufacturing Important Instruments In Chip Manufacturing - Semiconductor Coating - Cheersonic Wet electronic chemicals refer to various electronic chemical materials used in microelectronics and optoelectronic wet processes (mainly including wet etching, cleaning, development, interconnection, etc.). According to the purpose, it can be divided into general chemicals (also known as ultra-clean and high-purity reagents) and functional chemicals (represented by photoresist supporting reagents). Among them, the [...]

The Future Of Automotive Chips The Future Of Automotive Chips - Semiconductor Coating - Cheersonic At first, predicting when the automotive chip shortage will end may seem easy, with analysts estimating pre-pandemic levels by 2021. In other words, the tight semiconductor supply doesn't seem like it should last this long, as everyone expects production to be in line with demand within a few months. But that apparently didn't [...]

Current Situation of Lithography in China Current Situation of Lithography in China - Semiconductor Coating - Cheersonic In the process of chip production, tens of thousands of circuits need to be engraved on a small 7nm chip with optical materials, and this auxiliary optical material is photoresist. In the field of photoresist, materials are mainly divided into four types, namely g-line, i-line, KrF, ArF photoresist. short. The resolution [...]

Photoresist Classification Photoresist Classification - Spray Polyimide Photoresist - Cheersonic Photoresist, also known as photoresist, is a mixed liquid that is sensitive to light. Its components include: photoinitiators (including photosensitizers, photoacid generators), photoresist resins, monomers, solvents and other additives. The photoresist can transfer the required fine pattern from the photomask (mask) to the substrate to be processed through photochemical reaction and photolithography processes such as exposure and development.
