Engineering notes for equipment decisions
Checklists, decision frameworks and evaluation methods from real equipment projects — written for the engineers who have to defend the decision afterwards.
12 inputs to define before starting a Si DRIE project
Most DRIE projects that stall share one root cause: the application was never fully defined. Here are the twelve inputs to pin down first.

A single beautiful cross-section photo proves very little. What a meaningful DRIE demo looks like, and the criteria to agree in writing before processing starts.

Batch thermal processing remains the quiet backbone of power and sensor fabs. A framework for the vertical-vs-horizontal decision, and the evaluation data that actually settles it.
