WebBonded wafer grinding or ultra-thin grinding may cause edge chipping which is one of the critical issues leading to wafer breakage. Chipping may be induced by the rounded profile of the wafer's outer edges. The edge trimming process eliminates the rounded profile of the outer edge ensuring edge strength and chipping decrease. WebOct 6, 2024 · Lithography. Lithography is a crucial step in the chipmaking process, because it determines just how small the transistors on a chip can be. During this stage, the chip wafer is inserted into a lithography machine (that's us!) where it's exposed to deep ultraviolet (DUV) or extreme ultraviolet (EUV) light. This light has a wavelength anywhere …
