Silicon wafer breakage is possible during wafer production, handling, and transport. The residual stresses produced on the wafers while they undergo a series of rigorous production steps increase their risk of breakage.

The geometry of fracture associated with the propagation of cracks originating at the edges of (001) oriented, 200 mm diameter silicon wafers has been investigated under two regimes of high...

Oct 1, 2010 · The study shows that the whole wafer strength is largely dependent on its geometry design and damages due to wafer process. In brief, silicon wafer breakage can be controlled. There is a cause for every broken wafer and that cause can be found and corrected.

Jul 11, 2023 · Wafer backgrinding, also known as wafer thinning, plays a vital role in achieving this goal by regulating wafer thickness, which is necessary to manufacture ultra-thin wafers that are used to produce well-proportioned and high-density packaging in compact electronic devices.

Jun 21, 2023 · Silicon wafers are quite fragile and can be easily damaged if mishandled. Any sudden jolt or high vibration can cause the wafer to break or crack. Keep in mind that exposure to extreme temps or high humidity can cause the wafer to expand or contract.

6 days ago · In this article, we will find out how to solve the wafer semiconductor failure. It is illustrated through three parts: what wafer semiconductor failure is, the reason why it occurs and how to solve this problem.

Nov 3, 2015 · Wafer breakage during high temperature processing is a multi-million dollar problem in semiconductor manufacturing lines, the prime cost being in loss of product during the time taken to stop the line, recover the broken wafer, clean and restart the affected tool.

Wafers may break at a tool or weakened wafers may break later. Once attention is given to the main culprits and issues resolved, breakage goes down. A few specific examples will be described. GaAs wafer breakage has been accepted as a norm because of the extreme brittleness of wafers [1-3].

The stress required to break a wafer is greatly reduced if the wafer surface has a stress concentrator such as a preexisting crack. We need to analysis and discover how and why a wafer broke so that future occurrence can

Initial cracks are produced with an indenter at the edge of a conventional Si wafer, which was heated under temperature gradients to produce thermal stress. At temperatures where Si is still in the brittle regime, the strain may accumulate if a microcrack is pinned.
