Dumb question. Remember that whatever shape you create has to be one that you can cut out of a wafer. The wafer is a foot across and has many, many tiny copies of your chip etched into the surface. You then use a saw to slice it up into individual devices. Concave shapes are therefore contraindicated.
- ffhhj 4y agoSaw or laser?
- duskwuff 4y agoCan be either, but saws are more common. The process is referred to as "wafer dicing".
- croo 4y agoNothing about processor core layout is easily understandable and to have the insight you just gave needs experience with the actual process. Therefore this question by its nature is not dumb. Don't preface answers with "dumb question". It kills curiosity.
- db48x 4y agoI would say that this is the easiest part of layout to understand; it is a gross physical requirement that anyone who has cut a piece of paper with scissors can reason about, rather than an electrical or signal processing problem.
