Teaching Rationale And Relationship
Lectures provides the core material weekly problem solving sessions in semester 1 give students the opportunity to query material taught each week. Face-to-face lectures can be replaced with online synchronous sessions supported by non-synchronous videos if the public health situation requires it.
Practical clean room sessions in semester 2 provide an opportunity to gain experience of clean room processes used in chip fabrication and the techniques used in the characterisation of electronic devices. Taught lecture material covering chip fabrication processes provide the theory for the practical work.
Assessment Methods
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The coursework provides the opportunity for the student to demonstrate their knowledge and skills developed from the electronic device (semester 1) lecture course material. The exam in semester 2 assesses the student knowledge of device fabrication, while the formative oral assessment in semester 2 ensures the student has engaged and acquired key knowledge from the practical device fabrication and characterisation experience.
