Article summary

Sam Zeloof has successfully created a homemade integrated circuit with over 1000 transistors in his garage lab, using a polysilicon gate process. This achievement is a significant improvement over his previous attempts, which used a metal gate process. The new process allows for lower threshold voltage and better performance. Zeloof's work demonstrates the possibility of creating complex semiconductor devices outside of a traditional industrial setting.

What commenters say

• The softness or fuzziness of chip components is due to the limitations of photolithography and other manufacturing processes, which can cause rounded structures and imperfect edges.
• The use of ion beams, deposition, and lithography in chip manufacturing can lead to rounded structures and other imperfections.
• Modern chip manufacturing techniques have improved significantly since the 1990s, allowing for sharper edges and more precise control over component shapes.
• The process of making chips is inherently limited by the resolution of the machines used to expose the polymer resist, leading to imperfections and softness in the final product.
• The development of cleanroom-free, modularized fab technologies like MinimalFab could potentially make it easier for individuals and small organizations to create custom chips.
• The availability of such technologies could enable the creation of fully custom IP, testing, bonding, and packaging, similar to PCB services today.
• The performance of MinimalFab is likely to be limited by its feature size and wafer size, which may not be comparable to industrial-scale chip manufacturing.
• The potential applications of MinimalFab and similar technologies include the creation of custom CPUs, MEMS devices, and other complex semiconductor devices.
