In semiconductor manufacturing, a mask is sometimes called a reticle. [1] [2] In photolithography, several masks are used in turn, each one reproducing a layer of the completed design, and together known as a mask set. A curvilinear photomask has patterns with curves, which is a departure from conventional photomasks which only have patterns ...
Soldermask is a printed circuit board (PCB) manufacturing process that uses a chemical or thermosetting resin to coat a thin film on a circuit board, which can effectively form a layer of reliable protection to avoid unwanted short-circuiting and leakage of the circuit board, and to improve the reliability and electrical performance of the ...
Photolithography (also known as optical lithography) is a process used in the manufacturing of integrated circuits. It involves using light to transfer a pattern onto a substrate, typically a silicon wafer. The process begins with a photosensitive material, called a photoresist, being applied to the substrate.
The HDI layers are built on both sides of the traditional PCB one by one with microvias. The SBU process consists of several steps: layer lamination, via formation, via metallization, and via filling. There are multiple choices of materials and/or technologies for each step. [3] Microvias can be filled with different materials and processes: [4 ...
In electronics and photonics design, tape-out or tapeout is the final stage of the design process for integrated circuits or printed circuit boards before they are sent for manufacturing. The tapeout is specifically the point at which the graphic for the photomask of the circuit is sent to the fabrication facility. The name originates from the ...
