Metrigraphics Blog Why Additive Beats Subtractive in Ultra-Miniature Circuits

Sputtering and photolithography vs. chemical etching―the advantages are clear.Device makers have a choice of whether to specify an additive or subtractive process for fabricating the micron-scale circuits used in their products. Knowing the basic differences between the two is important because choosing the right one can make a big difference in the whether a circuit will perform as required.
